I am experiencing the following problem.
I was compiling my program on an operating system, and it compiled ok, without errors. I did not check if it was 32 bit or 64 bit architecture. But, it must be 32 bit, because,
Now my current system is
and when I try to compile the same program on this system, I receive the following error:
/usr/bin/ld: i386 architecture of input file `../../../..//libs/ftt-master.linux.a(math_tools.linux.o)' is incompatible with i386:x86-64 output''
Any help in this regard, how can I resolve this problem.
