riscv-rust-toolchain's Issues

Issue compiling on Debian Stretch

I get the following error when I try to "make toolchain" on my Debian Stretch machine:

CMake Error: The source directory "/home/michael/Code/risc_v/riscv-rust-toolchain/llvm" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.
Makefile:25: recipe for target 'llvm-configure' failed
make: *** [llvm-configure] Error 1

Any ideas?

riscv-rust-toolchain/riscv-binutils-gdb/gdb/guile/scm-ports.c:146:10: error: ‘scm_new_port_table_entry’ was not declared in this scope

I am trying to build the toolchain using make toolchain as described in the readme, but the build fails:

$BASEDIR in the output above refers to the directory into which I checked out riscv-rust-toolchain and is not an actual directory nor does this string actually appear in the output.

The issue appears to be the same as sifive/freedom-e-sdk#83.

I am using Arch Linux on this machine. Guile 2.2.3 is installed.

'make toolchain' fails due to CMake/ninja error

Ubuntu version 16.04 LTS
Linux kernel version 4.13

I'm trying to build this project, but I keep getting errors related to CMake believing my C compiler is incorrect:

$ make toolchain
<snip snip>
-- Check for working C compiler using: Ninja
CMake Error:
  The detected version of Ninja () is less than the version of Ninja required
  by CMake (1.3).



CMake Error: Internal CMake error, TryCompile generation of cmake failed

CMake Error at /usr/share/cmake-3.5/Modules/CMakeTestCCompiler.cmake:61 (message):
  The C compiler "/usr/bin/cc" is not able to compile a simple test program.

  It fails with the following output:

As far as I can tell, I do in fact have a sane C compiler - I used it to compile GCC for RISC V just today.

I'm not familiar with ninja - I previously got the error that I had too old a version of ninja (0.1.3) so I installed package build-ninja instead of ninja and ninja --version returns 1.5.1, but CMake doesn't seem to be able to detect this ninja for some reason.

Any ideas where I might be going wrong?

RV64 support?

I'm interested in testing the 64-bit capabilities of RISC-V with Rust, and I noticed you have a JSON file for RV32. I wanted to know if it would be easy to add 64-bit support by creating a RV64 JSON as well?

what is this error even mean??

Rust submodule fetch failed

Hi,

I just cloned the repo, it failed to fetch the rust submodule:

~ git submodule update error: no such remote ref 842ce79133db9632aaf9f7b4720e9bcb88e3914a Fetched in submodule path 'rust', but it did not contain 842ce79133db9632aaf9f7b4720e9bcb88e3914a. Direct fetching of that commit failed.

compile error on ubuntu 17.10

Hi,

I tried to build riscv-rust-toolchain on ubuntu 17.10 and I report I had some compile error.
At first compiler error was generated like "no such file or directory "llvm/Target/TargetSubtargetInfo.h" at src/rustllvm/PassWrapper.cpp.
So I modified like that:

Next, how can I use build-env.sh during build riscv-rust-toolchain?
During bulding, I got error like error while loading shared libraries: "libLLVM-6.0svn.so" and I needed to add LD_LIBRARY_PATH or LIBRARY_PATH. But build-env.sh can set them?

Could you check my modification is reasonable?

riscv64imac-unknown-none-elf cross compiler got "error: instruction requires the following: 'M' (Integer Multiplication and Division)"

When I cross-compile RISCV assembly instructions in file.asm with "rustc 1.60.0-nightly (5e57faa78 2022-01-19) riscv64imac-unknown-none-elf" toolchain.
I got the following error:

error: instruction requires the following: 'M' (Integer Multiplication and Division)
        mul t0, t0, a0
        ^

Please help， How should I avoid this error ?

"OBSOLETE" link broken

This repository is marked as obsolete, and the following is mentioned as replacement:

This is no longer the recommended way to get a Rust toolchain for RISCV. Instead, you can clone the riscv-rust/rust fork of Rust and build it as normal:

However, there is no riscv-rust/rust repository on github either. Did it move again?

Compile error on MacOS X 10.13.3

Am I insane for trying to build this on a Mac? (I could make a Docker container, and perhaps try to upstream it?) That said, it actually got surprisingly far and perhaps my problems are unrelated to my OS.

Perhaps something to do with the .dylib not being .so on Mac. Anywho, perhaps I should give it a go on Linux.

Testing on ubuntu/debian

What still needs to be done before upstreaming?

Upstream Rust is currently using LLVM 6 (rust-lang/rust#48782). This fork seems to have some additional commits (rust-lang/llvm@6ceaaa4...riscv-rust:rust-llvm-release-6-0-0-riscv). I guess upstreaming RISC-V support in Rust shouldn't be done until the non-Rust specific changes are in upstream LLVM?

It looks like rust-lang/lld doesn't have RISC-V support, so I suppose that is needed.

I see there's currently an issue with std on RISC-V (https://github.com/riscv-rust/rust/issues/2), but that probably shouldn't block upstreaming if libcore is working, since it is still useful for bare metal targets.

Anything else?

Built rustc can't create LLVM TargetMachine with riscv support

I'm trying to build the accompanying quickstart project, having built the toolchain, and I'm having little success. In particular, the rust compiler I've built doesn't seem to want to build for RISC V.

jakobw@ubuntu:~/riscv/riscv-rust-quickstart$ make build
xargo build --target riscv32i-unknown-none
error: failed to run `rustc` to learn about target-specific information

Caused by:

Readme contains link to the dead fork of rust

link https://github.com/riscv-rust/rust is broken

Problem is this is first search result which comes up when searching for "Risc-V rust" please, fix it, because it seems like rust on Risc-V is dead and this thing is obsolete.

# OBSOLETE

This is no longer the recommended way to get a Rust toolchain for RISCV.
Instead, you can clone the [riscv-rust/rust](https://github.com/riscv-rust/rust)
fork of Rust and build it as normal:

    ./x.py build

Rebase Rust

$BASEDIR in the output above refers to the directory into which I checked out riscv-rust-toolchain and is not an actual directory nor does this string actually appear in the output.
