QT5.5 on Raspberry Pi

[AQTStudent]

Hello,
I am trying to use the beginners tut http://qt-project.org/wiki/RaspberryPi_Beginners_guide
Somehow I ended up compiling 5.5.0 ...
Anyway, not the problem here as I can run any 5.4 application too then right?

The problem:

• qlibrary_unix.cpp:(.text+0x1330): warning: Using 'dlopen' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
  /mnt/rasp-pi-rootfs/usr/lib/arm-linux-gnueabihf/libdl.a(dlopen.o): In function dlopen': (.text+0xc): undefined reference to__dlopen'

Anyone a clue?

@sneubert
Thanks! However, when I execute it I get this:

• tueco@ubuntu:~/opt/cross-compile-tools$ sudo ./fixQualifiedLibraryPaths
  usage ./cmd target-rootfs path-to-target-toolchain-compiler

I'm not really sure what to do with it now..

nvm figured it out.. it's even in the tutorial.. totally looked over it!
Thanks!!
