gcc-apple compilation fails on Mac OS 10.9

[jcdx]

System: MacBook Pro, Intel Core i5, Mac OS 10.9, Xcode 5.0.2

Hi,

I would like to set up gentoo prefix on Mac OS 10.9. (used macports so far)
My aim is to use packages such as elmer fem, , freecad, gmsh and other scientific/engineering stuff from gentoo portage. I hope this is going to work

I followed these instructions: http://www.gentoo.org/proj/en/gentoo-alt/prefix/bootstrap-solaris.xml

As requested I cleaned up my bash_profile completely. So no macports from "/opt/local/..." and manually installed gcc-4.9 from HPC (https://sites.google.com/site/dwhipp/tutorials/mac_compilers#mlion)
should interfere with the boostrapping process.

$ gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
Target: x86_64-apple-darwin13.0.0
Thread model: posix

Until stage2 everything seems to work.

But stage3 failed when compiling gcc-apple.
$ ./bootstrap-prefix.sh $EPREFIX stage3

I also tried the procedure from: https://gist.github.com/ypresto/2145498
but it also failed when compiling gcc-apple.

$ CFLAGS="-march=native -pipe" emerge --oneshot --nodeps sys-devel/gcc-apple
I attached the output of the failed compilation, please tell me if you need further information.
There are also lots of warnings before.

I too am running into the same error.

Hi again,

so far no success but I tested some things and may be somebody find this useful so solve gentoo prefix problems on Mac OS X 10.9.

I followed this script https://gist.github.com/ypresto/2145498
but I did some small modifications.

I did step by step manually in order to find out which critical error occurs first.
This is my script. I put a comment on each package I could successfully emerge. All others are marked with "fail".

nice post!

I tried to apply this patch to check if it would work, however it didn't. Appears that compiler is ignoring the #if.

Using gcc-apple-4.2.1_p5666-r2.ebuild and its patch found on bugtracker [1] i've managed to install gentoo prefix on macos 10.9.1
