Forcing 32bit compilation on Mac OS X 10.6

I'm running Mac OS X 10.6.

How do I force configure to compile in 32 bit mode?

  • You could simply set the CFLAGS and CPPFLAGS :

    export CFLAGS=-m32
    
    export CPPFLAGS=-m32
    

    These flags will simply force gcc to use the -m32 option, which compiles into 32 bits mode.

    So if you only have one file to compile, you can use:

    gcc -m32 myfile.c
