If you install gcc-multilib-gcc, you might run into this dependency error:

error: failed to prepare transaction (could not satisfy dependencies)
:: removing gcc breaks dependency 'gcc=8.3.0-1' required by gcc-fortran
:: removing gcc breaks dependency 'gcc=8.3.0-1' required by gcc-objc

Until there is a proper fix, it should work to install these three packages together:

gcc-multilib-git gcc-fortran-multilib-git gcc-objc-multilib-git

Please let me know if someone knows how to correctly define the dependences in the PKGBUILD. (Maybe gcc-multilib-git should automatically pull gcc-fortran-multilib-git and gcc-objc-multilib-git?)

@SpaceboyRoss Unfortunately, I cannot reproduce. Can you give some more details? And more important, can you reproduce if you remove all old state? "gcc is not a commit" could indicate that it fails to checkout the sources.

Independent of that, I noticed that this package (gcc-multilib-trunk-git) is affected by the same build issue discussed in https://aur.archlinux.org/pkgbase/gcc-git/

/home/phil/aur/gcc-multilib-trunk-git/src/gcc/gcc/config/i386/i386.c: In function ‘const char* output_fix_trunc(rtx_insn*, rtx_def**, bool)’:
/home/phil/aur/gcc-multilib-trunk-git/src/gcc/gcc/config/i386/i386.c:19200:1: error: invalid operand in unary operation
19200 | output_fix_trunc (rtx_insn *insn, rtx *operands, bool fisttp)
      | ^~~~~~~~~~~~~~~~

I'll try to port the workaround from gcc-git.

Fixed _pkgver_base

@tuxsavvy I have integrated your patch. Thank you!

Package no longer compiles as of 8.0.0.* due to Intel Cilk Plus libraries being removed:

• https://gcc.gnu.org/git/?p=gcc.git;a=tree;h=69eb295335fbb14f450109cd75372e8e589806fe;hb=1bd23ca8c30f4827c4bea23deedf7ca33a86ffb5

• https://gcc.gnu.org/git/?p=gcc.git;a=tree;h=refs/heads/trunk;hb=refs/heads/trunk

It also appears that Cilk Plus is going to be deprecated in 2018 and will remain that way:

Here is a patch which addresses it. Ignore the first edit as I wanted to make use of SMP by tweaking make flags:

prepare() is better, thanks :)

And yes, the package builds for me, which the correct _pkgver_base (which I just saw in the git logs that you had fixed before my message last week, but I somehow missed there was a commit to pull, and had to figure out things myself).

I wasn't subscribed to this package's comments btw, but I am now :)
