Hi all,

While compiling on 64-bit Linux a package that will be executed on a 32-bit Linux ([--build=x86_64-unknown-linux-gnu] --host=i686-pc-linux-gnu), I am facing an issue with the value of the LD macro generated in libtool, as the libtool part of configure does not add the '-m elf_i386' option for LD to generate a 32-bit object/program.

Actually, the problem is that libtool.m4 checks for the build system type with $host, whereas it should be $build. I have understood that $build is the system on which the program is generated (64-bit in my case) and $host the system on which the program created (32-bit in my case) is meant to run. So the right macro should test build system, and not host.

You will find attached a fix proposal.

Thanks,

Eric PAIRE
