Hello,
My platform is AMD-64 running Fedora 4 64-bit version. Is there a way for me
to compile and generate 32-bit version of a program ( in C )? How does one do
that using GCC ? Since 64-bit version also install all the 32-bit
compatibility library, that should not be a problem, is it ?
One of the reasons I want to do this because I have an object file ( .o ) that
I need to link againts, but the object file is in 32-bit, and I don't have
the source to regenerate the object file. During linking, ld generates
warning :
/usr/bin/ld: warning: i386 architecture of input file `api/render.o' is
incompatible with i386:x86-64 output
and the program will segfaults if run, which does not happen if I compiled the
program in 32-bit machine. But since my working desktop is 64-bit, I am
wondering if there's a way for me to do it without having to look for 32-bit
machine.
Thanks for any help.
RDB
