Hi Hauke, In the past, I have done this (wth Qt4) by generating, then hand editing the CMakeCache.txt to change the location of the moc executable to the native one. Now that reading your post made me re-visit this it seems to have two problems. First, with Qt5 finder, it doesn't seem to expose the moc location in the cache. Also I recall doing it the way I described works only if your native version is exactly the same as the arm version, otherwise you get errors like "this header was generated with a different version of Qt".... It always seemed pretty brittle. Another way that I do this, is by generating a toolchain file, which forces cmake to look only inside the RPi root directory. This means it will find the cross compiled moc executable. Then I have qemu set up with the Linux binfmt driver so that I can execute arm binaries 'natively'.. This is not trivial, and requires setting up a wrapper so that qemu can find the arm linker-loader etc. but you may be able to use this as a solution. I (loosely) followed this guide, modifying the wrapper to my system. https://gentoo-handbook.lugons.org/proj/en/base/embedded/handbook/index.xml?style=printable&part=1&chap=5 Good luck. I'd also like to hear if there is a different solution to this problem. -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
