[(partially)SOLVED] Compiling QT5 SDK on a raspberry pi
I wanted to compile the sdk directly on the rpi(wasn't in a "hurry" + wanted to see how it would turn out).
Using this guide: http://qt-project.org/wiki/RaspberryPi_Beginners_guide, I checked out the sources, and ran a slightly modified ./configure. Because I wasn't trying to cross-compile, I removed the cross-compile and sysroot parameters:
@ ./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=/home/paulo/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /mnt/rasp-pi-rootfs -opensource -confirm-license -optimized-qmake -reduce-relocations -reduce-exports -release -make libs -prefix /usr/local/qt5pi@
@./configure -opengl es2 -device linux-rasp-pi-g++ -opensource -confirm-license -optimized-qmake -reduce-relocations -reduce-exports -release -make libs -prefix /usr/local/qt5pi@
After a while it finally finished, but the last lines were:
@Warning: Disabling pkg-config since PKG_CONFIG_LIBDIR is not set.
Warning: Disabling pkg-config since PKG_CONFIG_SYSROOT_DIR is not set.
qmake is broken
Could not determine the target architecture!
Turn on verbose messaging (-v) to see the final report.
The OpenGL ES 2.0 functionality test failed!
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
*** qtbase/configure exited with non-zero status.
I had not redirected stdout/stderr to anything, so something that might have been displayed before is lost, unless ./configure makes a log out of the errors? Somekind of log of what happened (the actual error message) would really help locating the problem.
The only errors/warnings I saw during the compilation were like this:
@/home/esa/sources/qt5/qtbase/include/QtCore/../../src/corelib/tools/qstring.h:300:17: note: the mangling of ‘va_list’ has changed in GCC 4.4

Am I possibly missing some dependency, or is there something else wrong with my environment, or compiling on the pi itself altogether? I could just set up a cross compiler in a vm, following the linked guide, but I'm interested in why this fails.
EDIT: I realised that the -v option does not require you to do the whole process again. Here is the output with the -v added to the command: "https://gist.github.com/3868593":https://gist.github.com/3868593
Seems that the version expects to be cross-compiled, and gives errors on CROSS_COMPILE not being set
So does anyone know if it is possible to compile qt on a pi or how to do it?
The error does not seem to have anything to do with the pi itself, as I also get it in my cross-compile environment on my x86 desktop machine. However I did find the fix to the problem:
I should have read the end of the guide, where it tells what to do if it can't determine architechture...
You just have to checkout the master branch on git
However I am having another problem (building on a x86 machine this time), and make does not seem to get through. I am posting about it in my other thread: http://qt-project.org/forums/viewthread/21114/
