[Python-Dev] How to configure with icc on Mac? (original) (raw)

I downloaded an evaluation copy of the Intel compiler for Mac and tried (so far unsuccessfully) to configure with it. I have tried:

CC=icc ./configure --prefix=$HOME/tmp/icc-python

That failed computing the size of size_t because it tries to incorrectly link with -lgcc_s.

Then I tried forcing it to not use gcc:

CC=icc ./configure --without-gcc --prefix=$HOME/tmp/icc-python

That failed because of a bug in configure.in:

    case $withval in
    no)     CC=cc
            without_gcc=yes;;
    yes)    CC=gcc
            without_gcc=no;;
    *)      CC=$withval
            without_gcc=$withval;;

It ignores the CC value on the command line. I fixed that like so:

    case $withval in
    no)     CC=${CC:-cc}
            without_gcc=yes;;
    yes)    CC=gcc
            without_gcc=no;;
    *)      CC=$withval
            without_gcc=$withval;;

and reran autoconf. Now I'm back to the -lgcc_s problem. "gcc_s" is not mentioned in configure. It's accessed implicitly. Poking around in the icc man page didn't yield any obvious clues. (I did try using the -gcc-name and -gxx-name flags. They didn't help.) Is there some way to configure Python for use with icc on a Mac?

Thanks,
