homebrew-avr's Issues

Not able to update toolchain

Hi!
About a year ago I installed the AVR toolchain on my mac using this guide. It worked like a charm, and I currently have avr-gcc 4.9.3 and avr-libc 2.0.0 installed.

I'm working on a project where I want to compile optiboot for the new ATmega48PB/88PB/168PB/328PB chips, but I'm getting an error saying that the device isn't supported (or in the list of supported devices).

In order to update the toolchain I tried to run the following command; resulting in an error:

$ brew upgrade avr-libc
Error: No available formula with the name "avr-libc"

... And trying to install avr-gcc@4 didn't work either

$ brew install avr-gcc@4

How can I update the toolchain in order to compile for the new *PB series?

Link Time Optimisation 6.2.0

I use homebrew-avr with Arduino-mk and have been for a while. Updating to the latest formula, I suffered a segmentation fault at the linking stage.

Doing some digging, this is due to the -flto flag, set by default for Arduino-mk (and presumably arduino builds) but missing from the 6.2.0 homebrew build. I'm not that well versed with the gcc compiler but Link Time Optimization (lto) seems to be merged into the latest branch and was working in the previous homebrew formulae - is there a reason it's missing from the homebrew build?

One can workaround it be manually setting the C++ flags - excluding -flto - but it would be nice to have it working by default.

Thanks.

brew install avr-libc no longer works

Hi. I think that the removal of brew install avr-libc is intended, as per #54. Would someone just clarify if that's right, and what the correct approach for installing avr-libc now is? Thanks.

Needs explicit path directives on avr-gcc 4.9.3

After upgrading to avr-gcc 4.9.3, I have to set the following compilation flags for ATmega328p, which were not required in the previous version. Could this be automated in somewhere else or should this be done always in this way?

Xcode and homebrew-avr

I would like to know how to use homebrew-avr with Xcode. Can you please list the steps please, and i can help in creating a wiki with those details.

Conflict of avr-gcc with gcc@7 from homebrew tap

Hi,

I just installed avr-gcc@7 and the install failed at the linking stage:

Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink lib/gcc/7/libcc1.0.so
Target /usr/local/lib/gcc/7/libcc1.0.so

In fact, I already had gcc@7 installed, and this is the reason for the clash.
Wouldn't it be possible to add a dependency from avr-gcc to gcc@7 instead of recompiling gcc in the avr-gcc formula?

Thanks
Will

Just rebased the repo, and going to upgrade some stuff

I will try to add some of those untill the end of the week (maybe borrowed from @jpommerening repo):

I brew removed everything and try installing the tool chain again but got an error saying that ISL can't be found after trying different versions (I'm sorry I can provide the real error, I closed my terminal window...)

Anyway, after some research it seems that isl has been updated in hombrew to v0.14 which is not supported by avr-gcc 4.9.x.

The work around is to brew tap homebrew/versions and to modify the formula to install isl012. Now the installation works and I can compile my code.

Do any of you have the same issue? If so, maybe we should find a fix as it is not really straight forward to first time users.

Or we can ask ourselves "why is --with-isl used?" Do we really need it to compile code on AVR?

avr-gcc@7 will not build on High Sierra (again!)

I see there are a few previous issues similar to mine, but none of the solutions in them (if any) have helped me.

I need to stay on avr-gcc version 7 for now as the QMK keyboard firmware and/or LUFA apparently have some issues with the new version at the moment. Now avr-gcc itself won't build when I attempt to install it.

Here is the output of 02.make. Lines 3252-3254 seem to be where the action is.

brew doctor didn't find anything. I tried untap/tap, cleanup, deleting cached downloads etc, no dice. Installing Homebrew onto an older Macbook Pro that hadn't had its Xcode command line tools updated in a while gave the same result before and after updating (so it doesn't appear to be the culprit).

Cannot compile with Arduino IDE and avr-gcc 8.2.0

I'm having an issue with building an Arduino app from the IDE. I get the following output:

...

exit status 1
Error compiling for board Arduino/Genuino Mega or Mega 2560.

However, the error does not happen when I run the failed command in the terminal. I would appreciate any ideas or feedback, maybe I need to move folders around? Thank you!

(Why does this not include binaries? Building this beast can easily take an hour. This is a huge waste of resources, and providing binaries would also avoid mystery errors like this.)

I've run through the following troubleshooting as suggested in other similar issues:

Using brew doctor, a lot of stuff was in the node folder regarding openssl, and v8. I moved the entire /usr/local/include/node folder to the desktop and ran:

$ brew remove avr-gcc avr-binutils
$ brew untap osx-cross/avr
$ brew cleanup -scf
$ brew upgrade
$ brew tap osx-cross/avr
$ brew install avr-gcc

Sorry for the Tarantino script, but the above error is what happened after the above troubleshooting. Any attempts to install prior to that resulted in the brew install hanging at make for a very very long time (I was warned that it would be at least 20 minutes. I'm on a 2017 MacBook Pro, and waited greater than an hour)

ATTiny828 not supported

avr-gcc-4.9.3 does not support attiny828 in mmcu options
Note: The included C files do have the required support (accessible with #define __AVR_ATtiny828__), but the command line tool seems to be missing it.

Older versions of gcc

As of today, we have 3 versions of GCC:

  • latest (6.3.0)
  • 4.9
  • 4.8

We don't have 5.x.

I'm wondering if we should have them all, or none at all. Doesn't really make sense to jump from 4 to 6. In homebrew they have all the versions from 4.6 to 5. My opinion would be to keep only the latest version of each big version:

  • 4.x
  • 5.x
  • 6.x
  • etc.

but don't bother with multiple versions of each.

And regarding binutils and avr-libc, only keep the latest version. If they are not compatible with older version of gcc, drop support of those versions of gcc.

what do you thing?

6.3.0 doesn't have pgmspace.h

I'm trying to compile QMK. It used to work fine with 6.2.0, but it looks like 6.3.0 is missing a required header.
6.2.0 had this file:
/usr/local/Cellar/avr-gcc/6.2.0/avr/include/avr/pgmspace.h
6.3.0 appears to have no equivalent. Am I doing something wrong? I just brew updated.

Thanks!

Common Include Path

Currently there is no good way to reliably link to the libraries in avr-libc. I'd like to see something akin to usr/local/include for avr, maybe usr/local/avr/(include | lib).

avr-libc could not install with `--sandbox` option

To solve this issue, it should bundle avr-libc into avr-gcc formula with resource syntax.

Installation is very CPU intensive

Today I installed homebrew-avr and was surprised when the fan on my MacBook started revving up. I checked Terminal and saw the title bar jumping between gcc and ruby with the fan whirring and the laptop practically shuddering -- very steampunk but I almost killed the installation convinced that it was stuck in an endless loop.

In the end, the installation did succeed, taking almost half an hour. I've installed Crosspack-AVR with brew last week (and brew uninstalled it today) and neither process took more than ten minutes with minimal fuss. Is this an issue?

I'm running MacOs 10.13.2 and Xcode Version 9.2 (9C40b).

Missing avr-libc breaks simavr formula 

~ $ brew install --HEAD simavr
==> Installing simavr from osx-cross/avr
Error: No available formula with the name "avr-libc" (dependency of osx-cross/avr/simavr)
==> Searching for a previously deleted formula...
Warning: homebrew/core is shallow clone. To get complete history run:
  git -C "$(brew --repo homebrew/core)" fetch --unshallow

Error: No previously deleted formula found.
==> Searching for similarly named formulae...
==> Searching local taps...
Error: No similarly named formulae found.
==> Searching taps...
==> Searching taps on GitHub...
Error: No formulae found in taps.

I suspect this was caused by #54 removing the avr-libc formula, and not changing simavr to use the resource, but I don't know how to test with a local formula to confirm this.

About the different versions of gcc

Hi there!

The formula still has two versions of gcc. Changing from one to the other used to work well just for me but I don't think it's a suitable way to do it.

I thought about this: why not avec different repository for different versions of gcc:

  • homebrew-avr - latest gcc, the most up-to-date version (now 4.9 but tomorrow 5.0 and so on)
  • homebrew-avr-4.8 - for the 4.8 version
  • and so on...

this way people can use which ever version they want.

what do you guys think?

Conflict with armmbed/formulae/arm-none-eabi-gcc

I already have arm-none-eabi-gcc installed. This causes a conflict when trying to install avr-gcc:

`==> Installing avr-gcc from osx-cross/avr

...

==> make install

Error: The brew link step did not complete successfully

The formula built, but is not symlinked into /usr/local

Could not symlink lib/libcc1.0.so

Target /usr/local/lib/libcc1.0.so is a symlink belonging to arm-none-eabi-gcc. You can unlink it:

brew unlink arm-none-eabi-gcc

Support for ATtiny441/841

It seems the latest version (avr-gcc -v says 4.9.3) has no support for ATtiny441 and the related ATtiny841, installed with default options (brew install avr-libc).

Am I missing something?
