Manage and switch between Solidity compiler versions

solc-select

A tool to quickly switch between Solidity compiler versions.

The tool is split into two CLI utilities:

• solc-select: manages installing and setting different solc compiler versions
• solc: wrapper around solc which picks the right version according to what was set via solc-select

The solc binaries are downloaded from https://binaries.soliditylang.org/ which contains official artifacts for many historial and modern solc versions for Linux and macOS.

The versioned binaries are stored in ~/.solc-select/artifacts/.

Quickstart

pip3 install solc-select

To automatically install and use a version, run solc-select use <version> --always-install.

Running on ARM (Mac M1/M2)

solc requires Rosetta to be installed. See the FAQ on how to install Rosetta.

Usage

By default, solc-select will install the most recent available Solidity file for your version. This will automatically be done when you run solc for the first time.

solc 

The global version of solc will automatically be set to to the latest version. You can reset this with the solc-select use <version> command:

$ solc --version
solc, the solidity compiler commandline interface
Version: 0.5.2+commit.1df8f40c.Linux.g++
$ solc-select use 0.4.24
Switched global version to 0.4.24
$ solc --version
solc, the solidity compiler commandline interface
Version: 0.4.24+commit.e67f0147.Linux.g++

Use SOLC_VERSION environment variable to override the global version:

$ solc --version
solc, the solidity compiler commandline interface
Version: 0.4.24+commit.e67f0147.Linux.g++
$ SOLC_VERSION=0.5.2 solc --version
solc, the solidity compiler commandline interface
Version: 0.5.2+commit.1df8f40c.Linux.g++

By default, solc-select will halt if you try to use a version that you do not have installed already. Use the --always-install flags to bypass this.

solc-select use 0.8.1 --always-install
Installing '0.8.1'...
Version '0.8.1' installed.

You can list all available versions with solc-select install:

$ solc-select install
Available versions to install:
0.3.6
0.4.0
...
0.8.0
0.8.1

FAQ

OSError: [Errno 86] Bad CPU type in executable

On newer solc-select versions, this might show as solc binaries for macOS are Intel-only. Please install Rosetta on your Mac to continue.

solc requires Rosetta to be installed. To see whether you have Rosetta installed on your Mac, run

pgrep -q oahd && echo Rosetta is installed || echo Rosetta is NOT installed

If it is not installed, it can be installed with the command

/usr/sbin/softwareupdate --install-rosetta --agree-to-license

solc-version not changing after running solc-select use [version] or setting SOLC_VERSION

Uninstall other installations of solc on your machine. solc-select re-installs solc binaries for your operating system and acts as a wrapper for solc. With duplicate solc installations, this may result in your solc version not being up to date.

"Unsupported Platform" on Windows

The solc-select version that supports Windows is currently in beta. Uninstall solc-select through pip3 uninstall solc-select and run

pip install solc-select==1.0.0b1

Alternatively, for the most up-to-date version, clone this repository and run

pip install . --user

Known Issues

SSL: CERTIFICATE_VERIFY_FAILED on running solc-select commands [investigation ongoing]

OS X

pip3 install certifi
/Applications/Python\ 3.8/Install\ Certificates.command

Python distributions on OS X has no certificates and cannot validate SSL connections, a breaking change introduced in Python 3.6. See StackOverflow post for additional details.

Connection refused [investigation ongoing]

pip3 uninstall solc-select 
pip3 install solc-select==0.2.0
solc-select install 

Try downgrading to solc-select version 0.2.0.

Our 0.2.1 version of solc-select pulls older Linux binaries from crytic/solc which seems to have introduced unexpected behavior in certain instances.

solc-select version changes, but solc --version does not match

Users seem to be experiencing situations in which the following command is successful:

solc-select use <version> 

However, when running the following command, it points to an older version of Solidity.

solc --version

solc-select is intended to work with custom binaries. This means that Solidity installed through other means (i.e: brew install solidity) will not work!.

Uninstall other versions Solidity from your computer.

solc-select's Issues

Can't seem to remove solc-select

Tried to install solc-select but it didn't quite work out for me so I'd like to remove it. Prior to installation I had solc installed using snap. I've removed the docker container, however when I try to install solc again using snap sudo snap install solc the command seems to be invoking solc-select instead:

mount: mounting /usr/bin on /workdir/usr/bin failed: Permission denied
mount: mounting /bin on /workdir/bin failed: Permission denied
mount: mounting /dev on /workdir/dev failed: Permission denied
mount: mounting /proc on /workdir/proc failed: Permission denied
mount: mounting /sys on /workdir/sys failed: Permission denied
chroot: can't execute 'chroot.sh': No such file or directory

I've also removed all files and folders that match solc$ on this machine, but this still happens. I'm confused. In what ways is solc-select interacting with snap?

Automatically change solc version depending on pragma

When running solc <file> currently, users have to change the solc-select global version, then run the solc file:

solc-select install <version> 
solc-select use <version> 
solc <file to execute> 

Example file:

pragma solidity 0.4.15;
contract Foo {
        function Foo() {
        }
}

When changing the pragma, it requires users to run the solc-select use <version> in their terminal to use the correct solc version. It would speed up testing significantly if the tool had the ability to change the version automatically.

Have the Dockerhub image auto-build every time Solidity is updated

Easiest way is to have our Docker image extend the official Solidity Docker image.

Update `solc-select install` to take a range of versions

The current API expects users to either provide all (which will install all versions) or specifically list out which versions they want to install.

It would be convenient for testing purposes to also allow users to provide a range of versions (i.e: 0.5.17-0.8.4)

Feature request: Support for a "solc use" command like with nvm

Add python types

We should add python types everywhere.

The codebase is small and straightforward, but types will help in the long term, and ease third party integrations

Commands to change global Solc --version do not work on Arch Linux

solc-select use 0.7.6
and
SOLC_VERSION=0.7.6

do not change the result of

solc --version

"use" is not found. in Linux

I have followed the given procedure but when try to use solc use 0.5.6 it gives "use" is not found

Better user experience around setting solc-select version

Currently, if a user tries to set the global version to a version they don't have installed, the error message tells them to run the alternative command.

It would be more efficient to directly ask users if they want to install 0.4.14 then, and then set the global version afterward, so they don't need to copy-paste the command.

$ solc-select use 0.4.14
You need to install '0.4.14' prior to using it. Use `solc-select install 0.4.14`

Unsupported solidity 0.6.12 in docker environment

I'm attempting to use the docker set up for echidna, and i am unable to sol-select solidity 0.6.12. It tells me that the max available version number is 0.6.9. Thanks!

STDOUT and STDERR are merged if STDIN is a TTY

solc-select uses docker run to execute solc inside a container. Docker has a known issue in which STDOUT and STDERR are merged if docker run is executed with the -t argument to create a new TTY. solc-select currently passes -t to docker run if STDIN is a TTY. solc does not ever need to execute in a TTY, so we should completely remove the -t logic from solc-select.

When I use the command solc-select install or solc-select install A_SOLC_VERSION(e.g, 0.4.25), I meet with the error as follows:

But these two commands indeed works on the inspur linux server(Ubuntu18.04). And I notice that there has been several identical issues published.

Automatically run `solc-select upgrade` on pip3 upgrades

To get the most up-to-date solc-select version, users have to run pip install solc-select --upgrade.

With the recent changes in refactoring, if solc-select detects the old architecture, it will print an error message and ask a user to run solc-select upgrade. As a result, users need to run these two commands to update solc-select, which is clunky:

pip install solc-select --upgrade
solc-select upgrade 

Before releasing the refactor and Windows support, find a way to automatically run the solc-select upgrade command on installations so users only need to run the first pip command.

Bash warnings if `solc` invoked with no arguments

Don't use POSIX-style string comparisons, since we're using bash anyway.

When I run the 'Solc select Install' command, the following error occurs. How can I solve it?

Introduce local solc version override

When we designed the initial solc-select architecture, we used a global-version file, which would be set when users run solc-select use <version>.

The current architecture easily supports the capturing of a different Solidity version in a set of smart contracts using a framework (i.e: Truffle/Hardhat), which should override the globally set version.

For example, even if the global version of a system is set with 0.8.4, the local solc version should be used over the global version. If nothing is set, then it should default to the global version:

global-version = 0.8.4 

local directory 1: 
  Truffle project Solidity version = 0.5.16 

local directory 2: 
   Hardhat project Solidity version = 0.4.25 

local directory 3: 
   nothing set; should use global-version 

Fails to download solc 0.8.x

Other versions work fine.

Temporary directory not included in docker path

When trying to use solc-select with the automated integration tests for Manticore on Mac, there's an error that solc can't reach the working directory because it's in a temporary directory like

""/var/folders/<2_chars>/<uuid>/T/tmpzos1e1fn"" is not found

I have patched the bin/solc docker invocation to also include:

--mount type=bind,source="/private/`getconf DARWIN_USER_TEMP_DIR`",target=`getconf DARWIN_USER_TEMP_DIR`

which fixes it, but I'm not sure how best to apply this so that Linux hosts don't get an error.

Furthermore, Linux temporary directory can be retrieved using

TMPDIR=`dirname $(mktemp -u -t tmp.XXXXXXXXXX)`

which can then be add as a mount too.

Also, for users that don't want to always include their temporary files, maybe we could have an environment variable to choose when to include the temporary directory in docker?

Add checksum

For every binary we should have a checksum and warn the user if it does not match

mac doesnt work

After I install the package completely in macosx 11.1 Beta and i restart the terminal for entering the solc-select and it doesn't find the command again. Now the only currently working way is installing the package on centos and they works without any workaround at all.

Lost support for solc < 0.4.10

With the new python refactoring, we lost the support for solc < 0.4.10

We are now using https://binaries.soliditylang.org/, which does not list versions that are too old, while in the past we used:

solc-select/scripts/install_solc.sh

Line 5 in 8a0ba47

curl -s -f -L "https://github.com/ethereum/solidity/releases/download/${1}/solc-static-linux" -o "$solc" && chmod +x "$solc" && echo "Installed solc-${1}"

Alternatively, we could get the missing binaries from: https://github.com/crytic/solc

solc --upgrade will not work for source installation setup

solc --upgrade is meant to update the list of available solc.

The current script pull the latest version on dockerhub:

solc-select/bin/solc

Lines 4 to 7 in c96e3e7

	if [[ "$1" == "--upgrade" ]]; then
	echo "Upgrading solc-select..."
	docker pull trailofbits/solc-select:latest
	else

As a result, local changes (ex: using a branch) will be erased.

I see two solutions:
1 - Update the source installation documentation, to mention that update must be done through docker build -t trailofbits/solc-select:latest .
2 - Somehow detect that the installation is a git version, and switch the command accordingly

I can submit a PR for solution 1, solution 2 seems more tricky.

Any thoughts?

Can not install solc on the Mac.

I am trying to install solc following our document,

docker pull trailofbits/solc-select
docker run --read-only -i --rm --entrypoint='/bin/sh' trailofbits/solc-select:latest -c 'cat /usr/bin/install.sh' | bash -e

when I run first command, it can pull some images, but for the second commands, nothing happens, so what should I do?

exec user process caused "exec format error"

I'm trying to run docker run --read-only -i --rm --entrypoint='/bin/sh' trailofbits/solc-select:latest -c 'cat /usr/bin/install.sh' | bash -e on Ubuntu arm 64 bit, but keep getting standard_init_linux.go:207: exec user process caused "exec format error". I was wondering if this is architecture related issue. Most of the answers I get from googling say add #!/bin/bash at the top of the script, but I'm guessing the presence of --entrypoint flag will cover that. Any idea?

Solc version not being switched

I am attempting to switch my solc version from 0.8.3 to 0.4.24, but this does not seem to be working as shown when I check the version, and when I try and build contracts using 0.4.24.

How to add older versions to the script?

Hello,

in the README.md, when typing --version, the oldest version is 0.4.11
However, when I type it, the oldest version is 0.0.24.
How can I tell the script to also add all the old versions?

Thank you,

Lukas

install problem

Sorry to bother you. Why I use the command "pip3 install solc-select" and then use "solc-select install 0.8.1 ",it shows "solc-select: not found"

solc-select doesn't recognize already install solc version

solc was installed on my system. Before installing the solc-select, it showed:

$ solc --version
solc, the solidity compiler commandline interface
Version: 0.8.6+commit.11564f7e.Darwin.appleclang

Once I installed solc-select, it didn't recognize my local version:

$ solc --version
No solc version set. Run `solc-select use VERSION` or set SOLC_VERSION environment variable.

While trying to use the local version:

$ solc-select use 0.8.6
You need to install '0.8.6' prior to using it. Use `solc-select install 0.8.6`

So I have to again install and use a solc version using solc-select

Add native, docker-less support for Linux

This should also resolve #12.

Task Description

There is no reason why solc-select would need to use Docker on Linux, since solc distributes statically linked Linux binaries.

The goal is to update the solc-select install script to:

• Detect whether it is being installed on Linux
• If so, run the scripts that are typically used to provision the Docker image

This may require modifying the install scripts such that they can both provision the Docker image (for non-Linux users) and install the scripts natively in Linux. The scripts that are installed in the Docker image are in the scripts/ directory.

There is currently a development branch that provides interim support for Ubuntu, but it uses Docker, which should not be necessary.

Acceptance criteria

• solc-select can install and upgrade itself on Ubuntu 18.04.2 LTS
• solc-select can install and upgrade itself on macOS
• solc-select behaves identically regardless of the OS on which it is run
• Documentation is updated to reflect the new capabilities, as well as any changes to the installation instructions

It would be nice to have solc-select packaged in a more standard way (e.g., Homebrew for macOS and Apt for Linux), but this is not necessary.

Required Skill

• Experience with Bash scripting
• Experience with Docker
• Experience with Linux

No experience with solc or smart contracts is required.

/usr/local/bin/solc: Permission denied

I tried to install solc-select as specified in the "Quickstart" description. When asked to overwrite /usr/local/bin/solc, the error, described in the title, occurs. Using -privileged flag in the Docker call does not solve this problem.

Validate inputted versions

Print out error message for user if they enter a solc version too large or too small. Both commands currently fail silently.

~$ solc-select install 0.9.1
~$
solc-select install 0.2.1
~$

Maximum is in the list.json with latestRelease tag

"latestRelease": "0.8.2"

Minimum is different for each distribution:

• For Mac, the minimum release is 0.3.6. https://github.com/ethereum/solc-bin/blob/gh-pages/macosx-amd64/list.json#L901
• For Linux, the true minimum release is 0.4.0. releases contains versions starting 0.4.10, but other binaries are available here: https://github.com/crytic/solc/tree/master/linux/amd64
• For Windows, the minimum release is 0.4.1. https://github.com/ethereum/solc-bin/blob/gh-pages/windows-amd64/list.json#L849

solc-runner ERROR

This error occurs when I run solc -- version

.solc-select/usr/bin/solc-runner:line 11: $BIN_DIR/solc-v$SOLC_VERSION $@

what should i do?

Add flag to `solc-select use` to install and change version

Convenience feature – but would be nice to add an option to run solc-select use <version> --some_flag, which installs and changes the solc version without the user needing to run solc-select install <version && solc-select use <version>

Means to self-upgrade directly from the Docker image

switch to the expected solc version automatically

I am using docker slighter and trying to use solc-select automatically. How it should be configured?

Currently it does not work even if I specify multiple versions using --solc-solcs-select

Any help would be appreciated.

Support for Windows v0.4.1 – v0.4.4

According to the json,0.4.3, 0.4.4 are missing for Windows, which is why they fail to install:

    "0.4.5": "solc-windows-amd64-v0.4.5+commit.b318366e.zip",
    "0.4.2": "solc-windows-amd64-v0.4.2+commit.af6afb04.zip",
    "0.4.1": "solc-windows-amd64-v0.4.1+commit.4fc6fc2c.zip"

Originally posted by @NatalieChin80 in #54 (comment)

Also, 0.4.1 and 0.4.2 are not the stable release builds, so this produces errors when trying to compile a file that expects version 0.4.1.

Provide a means for listing all available Solidity versions

Add option to only install a single or range of versions

Similar to #27, it would be nice to provide an option on the install script to specify which versions you would like to install, rather than the entire fetch list of releases.

This is useful in CI platforms, where you are generally only interested in one or a few specific versions at most.

For older versions, we can either bump up the ?per_page parameter on the Github API, or try to search for more versions using the pagination API if a specified version was not found. At the moment, 0.4.24 has been cut off from the list of versions, now that is it is not in the 25 most recent releases.

Persistent contract files

Solidity files appear to persist within the docker image between runs, so any changes on the local disk do no affect what dockerized compiler actually processes after the first time. Restarting Docker helps fix the issue.

Add linters to the CI

We can take some from slither:

• black: https://github.com/crytic/slither/blob/master/.github/workflows/black.yml
• pylint https://github.com/crytic/slither/blob/master/.github/workflows/pylint.yml

They both leverage the github super linter

Automatically determine the latest version of `solc` when building the Docker image

chroot: can't execute 'chroot.sh': No such file or directory

My dev machine is Ubuntu 18.04 and Docker version 18.09.5

I tried to install solc-select from source. The installation went through correctly. But when I tried to check the versions I had the following error:
$ solc --version

mount: mounting /usr/bin on /workdir/usr/bin failed: Permission denied
mount: mounting /bin on /workdir/bin failed: Permission denied
mount: mounting /dev on /workdir/proc failed: Permission denied
mount: mounting /proc on /workdir/dev failed: Permission denied
mount: mounting /sys on /workdir/sys failed: Permission denied
chroot: can't execute 'chroot.sh': No such file or directory

I uninstalled my solc installation and tried this again but had the same result.

Next, I uninstalled solc-select and ran the docker version. I had to update chmod for solc. But even after that I ran into the above errors when I tried to check the version again.
