Building target 32bit linux applications on 64bit host (Ubuntu 14.04)

[t3685]

Hi,

I need some help on how to build 32bit Qt5 linux applications on a 64bit linux host machine. Right I am compiling using a virtual machine, but I was wondering if there was way to directly build from my 64bit machine.

Anyone know a step by step guide?

Thanks,

Hi,

I think just passing -m32 flag to gcc or g++ while compiling the Qt App. should create it.

I tried this but I am getting the following error:

"bits/c++config.h: No such file or directory"

The problem is I have no experience with cross-compiling so I need all the help I can get :).

I solved the problem by making a new Qt kit using the proper makespec file. But now Qt Creator is complaining that it cannot find the right libraries. Is there are a way to get 32bit libraries on a 64bit linux.

On Ubuntu you can install ia32-libs as
@
sudo apt-get install ia32-libs

This has been deprecated in 14.04. And this doesn't really help if I want to play around with Qt versions.
