Maybe you forgot to setup the environment?

Softtoon

Hello

I am new to QT and i am following the "Raspberry Pi Beginners Guide" on your website because i want to cross compile for a raspberry pi 3.

Everything works fine untill "Compiling Qtbase" . Here i get this error

Project ERROR: Cannot run target compiler '/home/tonnie/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++'. Output:

sh: 1: /home/tonnie/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++: not found

Maybe you forgot to setup the environment?

But when i check the path, the file "arm-linux-gnueabihf-g++" is there.
I don't know what i have to do in the enviroment ????

Thanks in advance

Hi,

You should show the configure options you used to cross-compile Qt.

Softtoon

Hello

This is the command i use (copied from the website http://wiki.qt.io/Raspberry_Pi_Beginners_Guide)

./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=~/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /mnt/rasp-pi-rootfs -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi -hostprefix /usr/local/qt5pi

I followed the instruction on this website and everything works fine until here

@Softtoon said in Maybe you forgot to setup the environment?:

/home/tonnie/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++

What do you get if you run that line in your terminal ?

Hello

When ik run the ./configure command i get

cd qtbase

It complains that it cant find the compiler but the compiler is the correct location
~/opt/gcc-4.7-linaro-rpi-gnueabihf/bin

Do i have to add a path somewhere ? I am not familiar with linux

SGaist

What do you get if you call /home/tonnie/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-gcc --version ?

Hello

Sorry for the misunderstanding.
After running the command that you suggested i had to install gcc-arm-linux-gnueabihf
I did this by entering

sudo apt install gcc-arm-linux-gnueabihf

Now when i run
~/opt/qt5/qtbase$ ./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=~/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /mnt/rasp-pi-rootfs -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -make tools -prefix /usr/local/qt5pi -hostprefix /usr/local/qt5pi

I get this error :
ERROR: You cannot configure qtbase separately within a top-level build.

What does this mean ?

SGaist

Are you building from a clear source ?

You should rather do out of source builds, it makes things easier when you have to restart.

try the command below before runnig the ./configure :
sudo apt-get install lib32stdc++6

Had the same issue but it was showing no message between these two lines:

===================

I was using 32 bit compiler for -device-option CROSS_COMPILE I changed it to x64 and problem solved. it is now compiling.
