  • 0

I am trying to compile the Qt 5 libraries for my RPI, but it always crashes.

These are the guides I have tried to follow:

http://qt-project.org/wiki/RaspberryPi_Beginners_guide
http://qt-project.org/wiki/RaspberryPi

I have downloaded the cross-compiler and sysroot-image according to the guide and pulled the Qt5 sources from the git repo.

After following one of the guides I am now stuck at make.

This is the error I am receiving:

    Fix the paths of the libraries in your sysroot. Some libraries are symlinks to absolute paths which are broken when placed in your system. Check something like /home/esa/qtonpi/rpi_image/usr/lib/arm-linux-gnueabihf/libdl.so or similar. You should see those are broken symlinks to absolute paths. Fix all of those. In the documents you reported a script for this purpose is provided. Did you run it (https://gitorious.org/cross-compile-tools/cross-compile-tools/blobs/master/fixQualifiedLibraryPaths)?

    Try also to check this if you still encounter troubles: I wrote down some notes compiling a recent version from the git for the wheezy image.
