I am trying to install gcc 4.7.3 or greater. The specs of my machine are
as follows.
OS X 10.8.4
Darwin 12.4.0
gcc 4.2.1, configured with:
--disable-checking
--enable-werror
--prefix=/Applications/Xcode.app/Contents/Developer/usr/llvm-gcc-4.2
--mandir=/share/man
--enable-languages=c,objc,c++,obj-c++
--program-prefix=llvm-
--program-transform-name=/^[cg][^.-]*$/s/$/-4.2/
--with-slibdir=/usr/lib
--build=i686-apple-darwin11
--enable-llvm=/private/var/tmp/llvmgcc42/llvmgcc42-2336.11~28/dst-llvmCore/Developer/usr/local
--program-prefix=i686-apple-darwin11-
--host=x86_64-apple-darwin11
--target=i686-apple-darwin11
--with-gxx-include-dir=/usr/include/c++/4.2.1
I have performed the following steps thus far.
$ tar zxf gcc-4.7.3.tar.gz
$ mkdir objdir4.7.3
$ cd objdir4.7.3
$ /Users/DJ/gcc-4.7.3/configure
$ make bootstrap
This produces the following error
In file included from ./kinds.h:75:0,
from
/Users/DJ/scratch/gcc-4.7.3/libgfortran/libgfortran.h:232,
from /Users/DJ/scratch/gcc-4.7.3/libgfortran/fmain.c:4:
/Users/DJ/scratch/gcc-4.7.3/libgfortran/kinds-override.h:40:5: error:
#error "Where has __float128 gone?"
make[3]: *** [fmain.lo] Error 1
make[2]: *** [all] Error 2
make[1]: *** [all-target-libgfortran] Error 2
make: *** [bootstrap] Error 2
I have tried implementing the fix found here:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53731
I implemented this fix by first deleting everything in the objdir4.7.3
directory and then modifying .../gcc-4.7.3/Makefile.in and
.../gcc-4.7.3/Makfile.tpl as described in the fix. The fix required
adding (MULTISUBDIR) in one place in each file. I saved these changes as
a patched version in a new directory called .../gcc-4.7.3_patched.
I cd'ed into the objdir4.7.3 directory once more and then ran the
configure script in the pathed directory. The make bootstrap step
resulted in the same error.
