CodeBlocks compile program for 32bit computer - c++

Question

I'm trying to compile my code for a 32 bit system using CodeBlock default MinGW compiler adding the -m32 parameter, but I'm getting a lot of errors:
||=== Build: Debug in cONfuSioN (compiler: GNU GCC Compiler) ===|

EDIT: I fixed

Most builds of mingw.org and mingw-w64 only support either 32-bit or 64-bit. There are entirely separate toolchain distributions for 32-bit target than for 64-bit target.
You can have two toolchains installed side by side, but not have one toolchain with target switches.
(I have heard of someone who did do a multi-target single toolchain distro of mingw-w64 but chances are that is not what you have got installed already).
It sounds like you have only installed a 64-bit target version. You could look into also installing a 32-bit target toolchain of mingw-w64.
