[Solved] Qt Compiler Error: Looking in wrong location for cross compiler

[Skyence]

Hello,

I have been following the insturctions in the link below, in order to cross-compile Qt5 on the Rasberry Pi.
Instructions: http://raspberry-qt.org/

I beleive that I have successfully followed the instructions, but am getting hung up while trying to build the example project. Here is my Compile Output:
@ 16:46:21: Running steps for project pip...
16:46:21: Starting: "/usr/local/qt5pi/bin/qmake" /home/morgan/Programming/pip/pip.pro -r -spec devices/linux-rasp-pi-g++ CONFIG+=debug CONFIG+=declarative_debug CONFIG+=qml_debug

For some reason, which is probably pretty self evidant to users more experienced in Linux than I, it is looking for the compliler in the /home/stpease/ folder, which does not exist. In Qt Creator, I specified in Build&Run->Compilers the Compiler Path to be /opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++

Any help with this would be much appreciated! I have tried looking for existing help on this, but have been unsuccessful.

Much thanks in advance!

Hi and welcome to devnet,

@/usr/local/qt5pi/mkspecs/devices/linux-rasp-pi-g++/qmake.conf@

This is pretty strange, where did you install your qt5pi ?

[Skyence]

Thanks for the reply!

qt5pi is installed in /usr/local/. I was looked in qmake.conf, but do not see the problem. I tried to follow the dependencies to fine CROSS_COMPILE, but couldn't find the config file it is refrenced in.

Here is the qmake.conf file:
@#

include(../common/linux_device_pre.conf)

QT_QPA_DEFAULT_PLATFORM = wayland

QMAKE_LIBS_EGL = -lEGL -lGLESv2

contains(DISTRO, squeeze) {

Try searching for stpease in qt5pi

[Skyence]

Thanks for the help! I used grep to search the qt5pi directory and found all the references to /home/stpease and deleted it from the paths.

I've now succesfully cross compiled and ran a Qt application on the raspberry pi! Thanks again!

You're welcome !

Since it's now building correctly, please update the thread title prepending [solved] so other forum users may know a solution has been found :)
