[GAP Forum] Having trouble installing GAP 4.7.8

[Will Chen]

Here's the output from gcc -v

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr
--with-gxx-include-dir=/usr/include/c++/4.2.1

Apple LLVM version 6.1.0 (clang-602.0.53) (based on LLVM 3.6.0svn)

Target: x86_64-apple-darwin14.1.0

Thread model: posix

I'm trying to use your option 2. How do I install the gcc compiler with
homebrew? I think I've installed homebrew, and entered "brew install wget".

However, this is the output when I follow your instructions in (2):

Zephyr:gap4r7 wchen$ ls

CITATION config.log extern makepkgs sysinfo.in

INSTALL configure gap.ini pkg trans

Makefile.in configure.in gap.shi prim tst

bin doc grp small

cnf etc lib src

Zephyr:gap4r7 wchen$ make clean

make: *** No rule to make target `clean'.  Stop.

Zephyr:gap4r7 wchen$ export CC=/usr/local/bin/gcc-4.9

Zephyr:gap4r7 wchen$ ./configure --with-gmp=no

checking for gcc... /usr/local/bin/gcc-4.9

checking whether the C compiler works... no

configure: error: in `/Users/wchen/gap_installation/failed install/gap4r7':

configure: error: C compiler cannot create executables

See `config.log' for more details

Zephyr:gap4r7 wchen$ make

make: *** No targets specified and no makefile found.  Stop.

Zephyr:gap4r7 wchen$


:-(
