DescriptionInstalling the standard intel dmg for 3.11.1 from, and compiling a simple file:

I'm not sure if this was expected or not, but am reporting for completeness.

Could it be that under 10.6 gcc defaults to 64-bit mode, while under 10.5 it defaults to 32-bit mode? We'll have to figure this out. In the meantime, recompilation from sources is advised. Configure either with -cc "gcc -m32" or "gcc -m64" to make sure that you get the mode (32 or 64 bits) that you want.

Unfortunately, ./configure -cc "gcc -m32" won't compile:

gcc -c -DSYS_macosx -o i386.o i386.S || \
    { echo "If your assembler produced syntax errors, it is probably unhappy with the"; echo "preprocessor. Check your assembler, or try producing i386.o by hand."; exit 2; }
i386.S:95:32-bit absolute addressing is not supported for x86-64
i386.S:95:cannot do signed 4 byte relocation
i386.S:97:32-bit absolute addressing is not supported for x86-64
i386.S:97:cannot do signed 4 byte relocation
i386.S:100:suffix or operands invalid for `push'

-cc "gcc -m64" works fine.

(the ./configure for gcc -m32):

Configuration for the bytecode compiler:
        C compiler used........... gcc -m32
        options for compiling..... -fno-defer-pop -no-cpp-precomp -Wall -D_FILE_OFFSET_BITS=64 -D_REENTRANT
        options for linking....... -lcurses -lpthread
        shared libraries are supported
        options for compiling..... -fno-defer-pop -no-cpp-precomp -Wall -D_FILE_OFFSET_BITS=64 -D_REENTRANT
        command for building...... gcc -m32 -bundle -flat_namespace -undefined suppress -read_only_relocs suppress -o /a/path objs
Configuration for the native-code compiler:
        hardware architecture..... i386
        OS variant................ macosx
        C compiler used........... gcc -m32
        options for compiling..... -Wall -D_FILE_OFFSET_BITS=64 -D_REENTRANT
        options for linking.......
        assembler ................ as
        preprocessed assembler ... gcc -c
        profiling with gprof ..... supported
Source-level replay debugger: supported
Additional libraries supported:
        unix str num dynlink bigarray systhreads threads graph dbm labltk
Configuration for the "num" library:
        target architecture ...... ia32 (asm level 2)
Configuration for the "graph" library:
        options for compiling .... -I/usr/X11R6/include
        options for linking ...... -L/usr/X11R6/lib -lX11
Configuration for the "labltk" library:
        use tcl/tk version ....... 8.5
        options for compiling ....
        options for linking ...... -ltk8.5 -ltcl8.5
(This is with 3.11.0, since 3.11.1 doesn't work, as discussed elsewhere).

It seems that -cc "gg -m32" is not enough to build in 32-bit mode,
you need to also pass -as "as -arch i386" -aspp "gcc -m32 -c" to
the ./configure script.

Tested successfully with 3.11.1 on MacOS X 10.6.1 running on top of an Intel Core 2 Duo.

On this configuration, a bare ./configure with no argument is enough to build a 64-bit version.

Yes, this works for me too. Thanks.
