Hello I am trying to make an application on a 64-bit machine with -m32 option. I have add "-m32" in CFLAGS and "-L/usr/lib/gcc/x86_64-linux-gnu/4.4/32 -m32 -L/usr/lib32" in LDFLAGS. However I have got the following error : /usr/bin/ld: i386:x86-64 architecture of input file `/usr/lib/gcc/x86_64-linux-gnu/4.1.3/crtbegin.o' is incompatible with i386 output /usr/bin/ld: i386:x86-64 architecture of input file `/usr/lib/gcc/x86_64-linux-gnu/4.1.3/crtend.o' is incompatible with i386 output
These 'crt*' files are the default 64-bit x86_64 objects, the '/usr/lib/gcc/x86_64-linux-gnu/4.1.3/32' should have the 32-bit x86 equivalents.
I have 32-bit version of crtbegin.o and crtend.o in /usr/lib/gcc/x86_64-linux-gnu/4.4/32/ However gcc try to use 64-bit version from /usr/lib/gcc/x86_64-linux-gnu/4.1.3/.
The '-verbose' option for the linker would be nice in a case like this... One gives it with the '-Wl,<linker-option>', here '-Wl,-verbose' on the 'cc' command line. In any case it can be that the '-L' options will only add directories AFTER the normal ones, not BEFORE them! The GCC manual doesn't tell the order : -Ldir Add directory dir to the list of directories to be searched for â-lâ.
Does any one know how I can force gcc to use object files in /usr/lib/gcc/x86_64-linux-gnu/4.4/32/ ?
Why the '/usr/lib/gcc/x86_64-linux-gnu/4.1.3/32' doesn't have the 32-bit 'crtbegin.o' and 'crtend.o' ? Mixing the 4.4 ones isn't sane at all! Maybe you haven't added support for 32-bit linking into your gcc-4.1.3 toolchain at all via installing the 'glibc-32bit-dev*' or something packages?
