Thanks, Margarita. I've read it. But there is no answer to my question. I would like to know what needs to be fixed in the SDK to resolve this issue.

Intuetive I have guessed the reason of this issue. It is absence of file qt_lib_multimedia.pri in "mkspecs" directory. I took this file from QT for PC and put it into "mkspecs" directory of SDK. Now qmake runs without this error. But I do not sure that it is right and that application will work. And I do not understand why it is absent in SDK?

Hello Vladimir,

The qtmultimedia is not absent in the SDKs. If you get this error, it is probably due to a improper linking or difference in the version of Qt on the host's toolchain and the target's rootfs.

Best regards,
Kemal

Hello, Kemal,

Yes, qtmultimedia library is present, but "nokia project include file" (qt_lib_multimedia.pri) is absent for this library in the directory "/ti-processor-sdk-linux-am335x-evm-02.00.01.07/linux-devkit/sysroots/cortexa8hf-vfp-neon-linux-gnueabi/usr/lib/qt5/mkspecs/modules/" and qmake shows error message.

Best regards,
Vladimir
