I am testing cross build capability of CT. All experiments are based on Typhon32 running on Windows-10-64bit.

I could successfully cross build a simple app to Win32, Win64 and LinuxMint64, and resulting executable works fine. Pretty happy about the results so far!
But how do I cross build to the target LinuxMint32? For Linux Mint 64, there is a library x86_64-linux-gtk3 but that has no 32bit counterpart. What is the recommended way to build 32bit Linux in this situation?

Thanks!

Thanks Sternas!

But for some reason that does not work for me! Can you take a look at some of my screen shots?

My development machine is VirtualBox running Windows-7 Pro 64bit with 4GB RAM and 100GB hard drive.

Build target is Linux Mint 17.2 32 bit

These are the installed libraries in my setup

But I see only the following options in the drop down while selecting LCL Widgets

For some reason I cannot see qt4 in the drop down. What am I missing?
(On a side note I am not sure if qt4 will work with MATE or Cinnamon.)

Thanks! That worked, in the sense that I could create 32bit Linux executable.

Looks like I have to install QT library on Linux Mint 32 in order to run this. Are there gtk2 or gtk3 cross build libraries for Typhon IDE?

When I try to execute I am getting the following error:

error while loading shared libraries: libQt4Pas.so.5: cannot open shared object file: No such file or directory

I was trying to use gtk2 or gtk3 instead of QT. I could do that on Linux64 but not Linux32. That is what I am trying to understand, if I it is possible to get gtk2/3 for 32bit Linux.
I am still trying to understand the whole architecture. I am happy to help with CT/Lazarus development in the future, as much as I can.

On Windows OS
Typhon32 can build all possible CPU-OS-Platform matrix
Typhon64 has problem with all CPU-OS-Platform, because FreePascal 64 bits has problem to build all CPU-OS-Platform

For all other OSes, Typhon32 and Typhon64 have the same CrossBuild functionality.

For this reason we propose on Windows OS, to use Typhon32 and FPC32 for CrossBuild

This is the status now, in the future this can be change (I hope).

PS: CodeTyphon use NATIVE CrossBuild technology, we don't use "Virtual API" methodology.
