How to compile a 32-bit library version on a 64-bit Linux machine?

[dpcrd]

I'm trying to compile SDL in 32-bit mode on Ubuntu 24.04 with gcc. I need it because I want to develop with u8g2 with RIOT OS.

I followed the installation procedure, with these variations:

$ CFLAGS=-m32 ../configure --enable-audio=no --enable-power=no

But I get compilation error about incompatibilities between 32 and 64-bit binaries. What's the way to do it?
