I did a post about Win32-Linux32 in Cross Build Win32-Linux32 which yet to have a suitable answer. So I tried to do Linux 64bit to Linux 32bit and came out as same as Win32-Linux32 with following error:
/usr/local/codetyphon/fpc/fpc64/bin/x86_64-linux/i386-linux-ld: cannot find /lib/ld-linux.so.2

ld-linux.so.2 file is available in /usr/local/codetyphon/binLibraries/i386-linux

I badly need to compile a library for Linux 32bit as my Linux host application is 32bit(Firebird 1.5) and I making a Firebird UDF.

Hello.

Not sure to understand.

Is your main system Linux 64 bit and do yo want to compile a 32 bit Linux library?

IMHO, the most easy is not to do Cross-compilation but use the 32 bit Typhon in a multi-arch 64 bit system.

To resume: install CodeTyphon with "multi-arch" enabled then, load 32 bit Typhon for compile your 32 bit library.

My main system is 64bit and trying to compile 32bit.

I tried to install 32bit IDE but got following error in Ubuntu Budgie 64-bit with 6GB of RAM and with Multi-Arch enabled

Sir
Ubuntu Budgie 64-bit it's NOT MultiArch Distribution,
for this reason we don't enable CodeTyphon MultiArch ability in our CT-OS test info

For true MultiArch and MultiPlatform distributions my suggestion is
Debian 9.x, Fedora 28, Mageia 6 etc. more info

Many "Secondary" Linux Distribution do NOT support MultiArch
it's OS Packages and Libraries problem.
