I need to cross compile an application (written in C) using GNU autoconf/automake, but I cannot find which specific parameter values I have to pass to .configure to make it happen.

The system on which I'm compiling has an x86-64 architecture while the system on which the executable will run has an i386 architecture.

Googleing I found that I need to run

./configure --host=<cross-compiler for i386 architecture> --build=<my-system-architecture>

Is that right? Where can I find the information necessary to run correctly this command (i.e. parameter's values)?

  • Hi, it's actually easier than a "cross-compile" ... This question is nicely answered here https://stackoverflow.com/questions/3261909/build-32bit-on-64-bit-linux-using-an-automake-configure-script – Ahmed Masud Jul 25 '19 at 08:36

  • Hm, overlooked: Do you possibly intend not only to compile for different architecture variant, but OS as well (e. g. windows on linux machine)? *Then* you'd really need to do a cross compile... – Aconcagua Jul 25 '19 at 08:38
