How To Fix An Unknown Error When Cross Compiling My Qt Application To Raspberry-pi3

my program (QT/C++)is using a python module to download some video from google drive, it's work very well but I couldn't cross compile it for raspberry pi3. I am new in QT Cross C

Solution 1:

Basing on the solution of this problem Python compilation error: "LONG_BIT definition appears wrong for platform" .I changed in lib/python2.7/Include/pyconfig.h this line #define SIZEOF_LONG 8 bye this line #define SIZEOF_LONG 4 (explanation : '4' for 32 bits and '8' for 64 bits ).

but now I have a new error that i does't understand :::

t/usr/lib/arm-linux-gnueabihf -lQt5Widgets -lQt5Gui -lQt5Qml -lQt5Network -lQt5Xml -lQt5Core -Wl,-rpath-link,/opt/qtrpi/raspbian/sysroot/opt/vc/lib -lGLESv2 -lpthread

collect2: error: ld a retourné le statut de sortie 1

can anyone what is the meaning of this error ???
