Error: avr-binutils did not build

Is there a possibility to add a formula for avr-gcc 4.1.2?

Currently, installing this package will link the following files in a way that conflicts with installing non-avr gdb:

/usr/local/share/info/configure.info -> /usr/local/Cellar/avr-binutils/2.23.1/share/info/configure.info
/usr/local/share/info/bfd.info -> /usr/local/Cellar/avr-binutils/2.23.1/share/info/bfd.info

These should be linked as being specific to avr. Might need to patch AVR to look for these under different file name though.

Is it possible to clean up after uninstalling avr-libc right now despite uninstalling the library is still installed.

I'm not sure if this is specific to this homebrew formula, but has anyone else encountered this error?

Is it possible to support avr-size -C

It's very useful for inspecting your code size:
See the following patch: http://git.makehackvoid.com/cgi-bin/gitweb.cgi?p=mhvavrtools.git;a=blob_plain;f=mhvavrtools/patches/binutils-001-avr-size.patch;h=e80d28eae46217551d996a2253256c97d10aa4b5;hb=refs/heads/master

$ touch test.c
$ avr-gcc test.c
$

(successful)

$ avr-gcc -flto test.c
collect2: fatal error: cannot find 'ld'
compilation terminated.

According to fs_usage, collect2 is trying to find the linker using the name avr-avr-ld. A workaround is to create a symlink with the expected name:

$ ln -s avr-ld /usr/local/bin/avr-avr-ld
$ avr-gcc -flto test.c

(successful)

I'm insufficiently familiar with the gcc build process to readily determine what might need to change in the recipe to prevent this issue.

Hello. In trying to install avr-gcc I got the following error:

$ brew install larsimmisch/avr/avr-gcc

Please report this to the larsimmisch/avr tap!
If reporting this issue please do so at (not Homebrew/brew or Homebrew/core):

Let me know what else you'd need from me to help.
Thanks!

Hi, whey I try and build on my machine, the build fails.

bash$ brew -v install avr-binutils

There are plenty repos as:
https://github.com/jpommerening/homebrew-avr
https://github.com/larsimmisch/homebrew-avr
https://github.com/WeAreLeka/homebrew-avr

What do you think of joining efforts and avoiding duplication, by creating an org like homebrew-uC/homebrew-avr

And then we can also join suff from other uC archs 😃

i am also posting the same issue on the listed repos

Here is the error I get (Mac OS X 10.9.1):

Hi,

I have the following warning for deprecation when using your tap :

Anything you can do ?

Hi,

I'm trying to brew install -v avr-libc on my machine but to no avail, it keeps saying :

brew doctor is fine, and brew is up to date.

I'm having the following error :

But avr-ar seems present, as I can do :

$ xcrun -find gcc
/Applications/Xcode.app/Contents/Developer/usr/bin/gcc

And I have the command line tools from Xcode installed (with Xcode).

So I'm not really sure what I am doing wrong here, of if it is a bug. I googled the stuff but found no apparent solution to this problem.

Any hint ?

Thanks !

It fails because one dependency (mpfr) did not build:

You appear to have set $CFLAGS, perhaps you also need to tell GMP the
intended ABI, see "ABI and ISA" in the manual.
