Hi, I am following [https://wiki.qt.io/Raspberry_Pi_Beginners_Guide] for cross-compile Qt5 for Raspberry Pi.

Completed all the steps till fixing symlinks. While trying to run ./configure script, getting following error.

~/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 -prefix /usr/local/qt5pi -hostprefix /usr/local/qt5pi

@MakerSource said in Cross-compile QT5 For RPi - Error : Cannot compile a minimal program. The toolchain or QMakeSpec is broken.:

/opt/gcc-4.7-linaro-rpi-gnueabihf

You should try with 4.9
