[HowTo] Cross compile Qt5

[Sohaib Manzoor]

I executed only make, as instructed in the output of ./configure. Please scroll down for the errors "make" outputs. The make command stops after those errors. Here are the errors coming before the warnings:

[Cosik]

did you perform make always on fresh extracted Qt sources?
Did you compiled Mali drivers for yours linux?

It's a problematic for me to reproduce this because I don't have working lime.

[Sohaib Manzoor]

Yes I performed make on a newly extracted Qt source.
I also compiled Mali drivers for my target (Olimex A20) Linux. I ran the test which showed a colored triangle.

Okay, thanks a lot for your help. Please suggest anything that I could possibly be missing.

[Sohaib Manzoor]

Hi Cosik

i am  a beginner so i hope you don't mind my stupid questions .. the problem here is that i am  done with all these steps and it compiled fine now what i am supposed to do next ? Do i have to download and install a QT creator because i couldn't find it in the installed files folder?

[JoseQ]

Hi Cosik,
First of all, thank you for this guide, there is few documentation out there.

I'm experiencing some problems.

I'm downloading Qt-everywhere 5.5.0:
    wget http://www.mirrorservice.org/sites/download.qt-project.org/archive/qt/5.5/5.5.0/single/qt-everywhere-opensource-src-5.5.0.tar.gz

Also gitorious is going down so I'm downloading cross-compile-tools from:
    git clone https://github.com/shahriman/cross-compile-tools.git

And this Linaro toolchain:
    wget https://releases.linaro.org/14.04/components/toolchain/binaries/gcc-linaro-arm-linux-gnueabihf-4.8-2014.04_linux.tar.bz2

I'm woring in Ubuntu 14.04, and mounting A20 image through sshf.


The main errors I'm experiencing are on "./configure" stage, and they have to do with "determining target architecture", and with "OpenGL auto-detection":

  You might need to modify the include and library search paths by editing
  QMAKE_INCDIR_OPENGL_ES2, QMAKE_LIBDIR_OPENGL_ES2 and QMAKE_LIBS_OPENGL_ES2 in
  /home/jose/qt/qtbase/mkspecs/devices/linux-a20olimex-g++.
  

Right now I'm installing debian32 bit on VBox, maybe that would ease some things.


I would really appreciate your help.

Thanks
