Description
RTA test downloads Qt src achive, compiles it statically and uses that build to compile an example. Gcc, clang and MinGW builds work fine, but the MSVC test has linker errors when compiling the example:
Qt6Gui.lib(qplatformsystemtrayicon.cpp.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MD_DynamicRelease' doesn't match value 'MDd_DynamicDebug' in mocs_compilation.cpp.obj Qt6Gui.lib(qplatformgraphicsbuffer.cpp.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in mocs_compilation.cpp.obj Qt6Gui.lib(qplatformgraphicsbuffer.cpp.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MD_DynamicRelease' doesn't match value 'MDd_DynamicDebug' in mocs_compilation.cpp.obj Qt6Gui.lib(qplatformgraphicsbufferhelper.cpp.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in mocs_compilation.cpp.obj Qt6Gui.lib(qplatformgraphicsbufferhelper.cpp.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MD_DynamicRelease' doesn't match value 'MDd_DynamicDebug' in mocs_compilation.cpp.obj Qt6Gui.lib(qsimpledrag.cpp.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in mocs_compilation.cpp.obj Qt6Gui.lib(qsimpledrag.cpp.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MD_DynamicRelease' doesn't match value 'MDd_DynamicDebug' in mocs_compilation.cpp.obj Qt6Gui.lib(qwindowsfontengine.cpp.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in mocs_compilation.cpp.obj Qt6Gui.lib(qwindowsfontengine.cpp.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MD_DynamicRelease' doesn't match value 'MDd_DynamicDebug' in mocs_compilation.cpp.obj Qt6Gui.lib(qwindowsfontenginedirectwrite.cpp.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in mocs_compilation.cpp.obj Qt6Gui.lib(qwindowsfontenginedirectwrite.cpp.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MD_DynamicRelease' doesn't match value 'MDd_DynamicDebug' in mocs_compilation.cpp.obj Qt6Gui.lib(qfontengine_ft.cpp.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in mocs_compilation.cpp.obj Qt6Gui.lib(qfontengine_ft.cpp.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MD_DynamicRelease' doesn't match value 'MDd_DynamicDebug' in mocs_compilation.cpp.obj Qt6Gui.lib(qshapedpixmapdndwindow.cpp.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in mocs_compilation.cpp.obj Qt6Gui.lib(qshapedpixmapdndwindow.cpp.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MD_DynamicRelease' doesn't match value 'MDd_DynamicDebug' in mocs_compilation.cpp.obj Creating library quickwidget.lib and object quickwidget.exp LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library
Steps to repro:
Download and extract Qt6.0.1 sources, configure Qt:
cmake -DCMAKE_C_COMPILER=cl.exe -DCMAKE_CXX_COMPILER=cl.exe -GNinja -DCMAKE_BUILD_TYPE=Release -DQT_BUILD_EXAMPLES=OFF -DBUILD_WITH_PCH=OFF -DOPENSSL_ROOT_DIR=C:\openssl\include\.. -DFEATURE_system_zlib=OFF -DPostgreSQL_ROOT=C:\Utils\postgresql\pgsql\lib\.. -DQT_BUILD_TESTS=OFF -DBUILD_SHARED_LIBS=OFF C:\Users\qt\RTA\src-6.0.1 -DCMAKE_INSTALL_PREFIX:PATH=C:\Users\qt\RTA\src-6.0.1\qtbase
Compile Qt: cmake --build . --parallel -> compilation ok (build log attached)
Copy example qtdeclarative\examples\quick\quickwidgets\quickwidget out of the source tree to C:\Users\qt\RTA\tmp\quickwidget
Add above built static Qt to PATH and set the CMAKE_PREFIX_PATH to [static_build_dir]/qtbase/lib/cmake
Compile with cmake CMakeLists.txt and cmake --build . --parallel -> linker errors
As said, same test with MinGW (cmake -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++ -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++ -DCMAKE_BUILD_TYPE=Release -DQT_BUILD_EXAMPLES=OFF -DOPENSSL_ROOT_DIR=C:\openssl\include\.. -DFEATURE_system_zlib=OFF -DFEATURE_system_tiff=OFF -DFEATURE_system_freetype=OFF -DFEATURE_system_jpeg=OFF -DPostgreSQL_ROOT=C:\Utils\postgresql\pgsql\lib\.. -DQT_BUILD_TESTS=OFF -DBUILD_SHARED_LIBS=OFF C:\Users\qt\RTA\src-6.0.1 -DCMAKE_INSTALL_PREFIX:PATH=C:\Users\qt\RTA\src-6.0.1\qtbase) works just fine, the quickwidget application is compiled without errors.
