Cross compiling getting error gnu/stubs-32.h: No such file or directory

While trying to cross compile raspberry pi I'm getting the following error message
In file included from /home/Raspi/qt6_build/sysroot/usr/include/features.h:485, from /home/Raspi/CrossCompiler/cross-pi-gcc-10.2.0-0/arm-linux-gnueabihf/include/c++/10.2.0/arm-linux-gnueabihf/bits/os_defines.h:39, from /home/Raspi/CrossCompiler/cross-pi-gcc-10.2.0-0/arm-linux-gnueabihf/include/c++/10.2.0/arm-linux-gnueabihf/bits/c++config.h:518, from /home/Raspi/CrossCompiler/cross-pi-gcc-10.2.0-0/arm-linux-gnueabihf/include/c++/10.2.0/bits/stl_algobase.h:59, from /home/Raspi/CrossCompiler/cross-pi-gcc-10.2.0-0/arm-linux-gnueabihf/include/c++/10.2.0/memory:63, from /home/Raspi/qt6_build/qt/build/src/plugins/platformthemes/gtk3/QGtk3ThemePlugin_autogen/EWIEGA46WW/moc_qgtk3dialoghelpers.cpp:9, from /home/Raspi/qt6_build/qt/build/src/plugins/platformthemes/gtk3/QGtk3ThemePlugin_autogen/mocs_compilation.cpp:2: /usr/include/x86_64-linux-gnu/gnu/stubs.h:7:11: fatal error: gnu/stubs-32.h: No such file or directory 7 | # include <gnu/stubs-32.h>
I don't understand why cmake is searching for include files in usr/include/x86_64-linux-gnu/gnu/ even though the cross compiler seems to be configured correctly

Probably because of different version of OS? Could you please share history and OS version for raspberry pi.

After further investigation it seems that the following line are missing in the CMake Toolchain file provided:
set(ENV{PKG_CONFIG_PATH} "") set(ENV{PKG_CONFIG_LIBDIR} ${CMAKE_SYSROOT}/usr/lib/pkgconfig:${CMAKE_SYSROOT}/usr/share/pkgconfig) set(ENV{PKG_CONFIG_SYSROOT_DIR} ${CMAKE_SYSROOT})

After adding these line the issue was resolved

Are you using different toolchain? I did not see this issue?

[Rhvarrier]

Yes I'm using gcc-10.2 for armv6

Nice. That is why you see this issues. Are you able to compile it successfully ? If it is so, could you please share the exact link of the toolchain ? And is there any additional steps that you have done ? I have not tried it with default toolchain, I can try and add to the page for other people.

thanks.
