Hi there,
just want to inform the list for whoever who's interested how to compile
GDC on Mac OS X Lion because it was tricky.
The first steps do as explained here:
https://bitbucket.org/goshawk/gdc/wiki/Home#!installation
Be sure to have the libraries installed via MacPorts. Clone the
repository, download and unpack gcc.
Before configuring, completely disable the AVX check in the i386 GCC
driver by editing gcc/config/i386/driver-i386.c commenting out the line
has_avx = ecx & bit_AVX;
We have to do this because the assembler (as) delivered with MacOS
doesn't support AVX. You could also try to use clang as assembler but it
doesn't support the full AVX instruction set. Also you could try the
binutils of MacPorts (GAS), but this doesn't - unfortunately - support
reliable Mach-O output :-(
Now use as configure line:
./configure --enable-languages=d --disable-bootstrap --disable-nls
--prefix=/opt/local
--with-bugurl="https://bitbucket.org/goshawk/gdc/issues";
--enable-checking=yes --disable-libgomp --disable-libmudflap
--with-gmp=/opt/local --with-mpfr=/opt/local --with-mpc=/opt/local
--with-arch=native --with-system-zlib=/opt/local --disable-multilib
--enable-fully-dynamic-string
This may not be perfect, but it works. --with-system-zlib is necessary
if you don't want the famous GCC_NO_EXECUTABLES error. The paths have to
point into your MacPorts installation directory (with gmp, mpfr and
libmpc). And what's most important: The whole GCC configuration won't
work with --disable-shared. I don't know why but it just works without.
--enable-fully-dynamic-string is necessary because the system libs of
Mac OS also seem to use this - otherwise you would get memory errors.
Build the monster with
make -j2 2>&1 | tee build.log
and install with
make install
and you'll get a clean installation:
--- %< ---
andres-macbook-pro:objdir aw$ gdc -v
Using built-in specs.
COLLECT_GCC=gdc
COLLECT_LTO_WRAPPER=/opt/local/libexec/gcc/x86_64-apple-darwin11.3.0/4.6.2/lto-wrapper
Target: x86_64-apple-darwin11.3.0
Thread model: posix
gcc version 4.6.2 20111026 (gdc 0.31 - r796:f4b81c81e760, using dmd
2.057) (GCC)

Hope this helps! :-)
