Error while loading shared libraries during cross-compiling

feniks_fire

Well if I add this in my *.pro file:

QT += core

I have error when I try cross-compiling:

error while loading shared libraries: libQt5Core.so.5: cannot open shared object file: No such file or directory

Anyone knows the solution? Maybe I must installing some library in rpi?

Hi,

Did you cross-compile Qt ?

feniks_fire

I not very understand what you mean.
I think the raspberry don't have the library, maybe install qt in raspberry would help?

feniks_fire

Yeah, I have right. I copy all Qt library to RPI and use this in rpi terminal:

    export LD_LIBRARY_PATH="/home/pi/QtBase-5.7.0/lib"
    ./Test

and everything work.
Tomorrow I'll try just install qt in rpi, and this should work without terminal.
Another topic solved.
