Makefile and cross-compiling

Added by Marco Trapanese almost 13 years ago

Hello,

I finished a small project using QtCreator as IDE (no Qt code at all).

I tested it on my x86 machine, but now I need to cross-compile to arm (arm-linux-gnueabi-g).

I've already compiled wt for arm and placed everything in ~/arm.

I'd like to know how to change the makefile in order to crosscompile. In a Qt-related forum I shall ask how to setup QtCreator to do the job automagically.

This is the current makefile:

It's easy to change the compiler and linker settings.

But what about the other items?

Ok, I found a way, but it's so awful that I don't post it now. In the next days I'll try to find a better solution and I will come back here. If anyone is interested in.

Did you ever find a good solution for this? I know this is a bit old but I'm interested in your results.
