Building zlib libz.a for 32 bit

Question

I am trying to compile a 32-bit version (MinGW) of a program I wrote using zlib. Until now, I've never has to compile for 32-bit so the version of zlib I compiled from source (libz.a) is 64-bit. I tried to rerun the makefile in the zlib-1.2.5 directory but it only compiles a 64bit version of libz.a.

I can't seem to find an option to build 32-bit.

Does anyone know how to do this?

Thanks!

Answer 1

Checking the configure file, you can see some env.

On 64bit debian, following command line will build the 32bit version of libz

CFLAGS=-m32 ./configure

Answer 2

It turns out I had to get the 32bit version of MinGW and compile it with that. I was using MinGW64.
