Cross compile error

[Softtoon]

Hello

When i run
./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=$RPI_TOOLCHAIN -sysroot $RPI_SYSROOT -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi -skip qtwebkit

i get the error below.
I am a newbie in the world of cross compiling for my Raspberry pi. What could be the problem here

Error:
Could not determine the target architecture!
Turn on verbose messaging (-v) to see the final report.
The OpenGL ES 2.0 functionality test failed!
Use of pkg-config is not enabled, maybe you want to pass -force-pkg-config?
You might need to modify the include and library search paths by editing
QMAKE_INCDIR_OPENGL_ES2, QMAKE_LIBDIR_OPENGL_ES2 and QMAKE_LIBS_OPENGL_ES2 in
/home/tonnie/Qt/5.4/Src/qtbase/mkspecs/devices/linux-rasp-pi-g++.

Hi and welcome to devnet,

What do RPI_TOOLCHAIN and RPI_SYSROOT contain ?

[Softtoon]

Hello

I have sent these commands
export RPI_SYSROOT=/mnt/rasp-pi-rootfs
export RPI_TOOLCHAIN=~/crosscompile-tools/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-
Here i followed the tutorial from https://medium.com/@amirmann/how-to-cross-compile-qt-for-raspberry-pi-3-on-linux-ubuntu-for-beginners-75acf2a078c

In the mean time i am folling another turorial on "http://wiki.qt.io/Raspberry_Pi_Beginners_Guide" website called "Raspberry Pi Beginners Guide"

Here you have to donwload the cross compile toolchain. I downloaded it from
"wget http://de.sourceforge.jp/projects/sfnet_rfidmonitor/downloads/crosscompilation-resources/gcc-4.7-linaro-rpi-gnueabihf.tbz"
When i execuut "tar -xf gcc-4.7-linaro-rpi-gnueabihf.tbz", i get this error

bzip2: (stdin) is not a bzip2 file.
tar: Child returned status 2
tar: Error is not recoverable: exiting now

I have done the file command like "file gcc-4.7-linaro-rpi-gnueabihf.tbz"
Result : gcc-4.7-linaro-rpi-gnueabihf.tbz: HTML document, UTF-8 Unicode text, with very long lines, with CRLF, LF line terminators

Both turorials gave me trouble :)
My goal is to use the Raspberry pi3 B+ with QT5

Thanks for your help.

You’re downloading the page where the download should happen. You don’t have direct access to the file.
