    Description

      when building qtbase static:

      /usr/bin/cmake -DFEATURE_developer_build=ON -DBUILD_SHARED_LIBS=OFF -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_COMPILER=/usr/bin/gcc-10 -DCMAKE_CXX_COMPILER=/usr/bin/g++-10 -G Ninja -DCMAKE_CXX_FLAGS=-Wfatal-errors /home/andreasbuhr/development/qtdev/qtbase 2>&1 | tee buildlog.txt

      it fails to build with errors like

      FAILED: tests/auto/corelib/io/qprocess/testProcessEcho2/testProcessEcho2

collect2: error: ld returned 1 exit status

      The reason is that the order in the linker command line is wrong:

      On the command line,

      src/corelib/CMakeFiles/Core_resources_1.dir/./.rcc/qrc_mimetypes.cpp.o

      appears after

      lib/libQt6Core.a

      . This cannot work, as qrc_mimetypes relies on libQt6Core.a. Changing the linker command line manually from

      /usr/bin/g++-10 -Wfatal-errors -g -Wl,--gc-sections -Wl,--enable-new-dtags tests/auto/corelib/io/qprocess/testProcessEcho2/CMakeFiles/testProcessEcho2.dir/testProcessEcho2_autogen/mocs_compilation.cpp.o tests/auto/corelib/io/qprocess/testProcessEcho2/CMakeFiles/testProcessEcho2.dir/main.cpp.o -o tests/auto/corelib/io/qprocess/testProcessEcho2/testProcessEcho2  lib/libQt6Core.a  lib/libQt6Core_qobject.a  -lpthread  /usr/lib/x86_64-linux-gnu/libz.so  /usr/lib/x86_64-linux-gnu/libdouble-conversion.so  -lm  /usr/lib/x86_64-linux-gnu/libicui18n.so  /usr/lib/x86_64-linux-gnu/libicuuc.so  /usr/lib/x86_64-linux-gnu/libicudata.so  /usr/lib/x86_64-linux-gnu/libpcre2-16.so  -ldl  /usr/lib/x86_64-linux-gnu/libglib-2.0.so  /usr/lib/x86_64-linux-gnu/libgthread-2.0.so  /usr/lib/x86_64-linux-gnu/librt.so  src/corelib/CMakeFiles/Core_resources_1.dir/./.rcc/qrc_mimetypes.cpp.o

      to

      /usr/bin/g++-10 -Wfatal-errors -g -Wl,--gc-sections -Wl,--enable-new-dtags tests/auto/corelib/io/qprocess/testProcessEcho2/CMakeFiles/testProcessEcho2.dir/testProcessEcho2_autogen/mocs_compilation.cpp.o tests/auto/corelib/io/qprocess/testProcessEcho2/CMakeFiles/testProcessEcho2.dir/main.cpp.o -o tests/auto/corelib/io/qprocess/testProcessEcho2/testProcessEcho2 src/corelib/CMakeFiles/Core_resources_1.dir/./.rcc/qrc_mimetypes.cpp.o lib/libQt6Core.a  lib/libQt6Core_qobject.a  -lpthread  /usr/lib/x86_64-linux-gnu/libz.so  /usr/lib/x86_64-linux-gnu/libdouble-conversion.so  -lm  /usr/lib/x86_64-linux-gnu/libicui18n.so  /usr/lib/x86_64-linux-gnu/libicuuc.so  /usr/lib/x86_64-linux-gnu/libicudata.so  /usr/lib/x86_64-linux-gnu/libpcre2-16.so  -ldl  /usr/lib/x86_64-linux-gnu/libglib-2.0.so  /usr/lib/x86_64-linux-gnu/libgthread-2.0.so  /usr/lib/x86_64-linux-gnu/librt.so

      solves the problem. But one cannot fix each linker command manually.
