Undefined reference to qInitResources
-
Hi,
I am trying to port my C++ application to Android.
Unfortunately, I got error messages like:C:\myGame\src\shaders/carMaterial.cpp:28: error: undefined reference to 'CarMaterial::qInitResources_materials()'Android project files are made from CMakeList - without resources everything works fine.
My CMakeList contains these lines:(...) QT5_ADD_RESOURCES("./resources/qml.qrc") SET(ALL_SOURCES ${__main_HDRSRC} (...) ${__resources_HDRSRC} ) IF(ANDROID) ADD_LIBRARY(myGame SHARED ${ALL_SOURCES}) ELSE() ADD_EXECUTABLE(myGame WIN32 ${ALL_SOURCES}) ENDIF() (...)I used toolchain from https://github.com/LaurentGomila/qt-android-cmake
And command to making project files:cmake -DCMAKE_CXX_COMPILE_FEATURES=cxx_constexpr -DCMAKE_CXX_FLAGS="-std=gnu++14" -D ANDROID_NATIVE_API_LEVEL=android-19 -D CMAKE_TOOLCHAIN_FILE=../../qt-android-cmake/toolchain/android.toolchain.cmake -D CMAKE_MAKE_PROGRAM="%ANDROID_NDK%/prebuilt/windows-x86_64/bin/make.exe" -D QTDIR="%QTDIR%" -G "MinGW Makefiles" ..Any idea how to solve this problem?

My OS: Windows 10@Montjet said in Undefined reference to qInitResources:
QT5_ADD_RESOURCES("./resources/qml.qrc")
This doesn't look right... You need something like:
qt5_add_resources(RC_SRC "resources/qml.qrc") ... add_library(myGame SHARED ${ALL_SOURCES} ${RC_SRC})That should fix your issue. Basically that error message is saying you didn't include your resources in the shared object file so they can't be loaded.

Okay, I got it!
I moved every Q_INIT_RESOURCE(...) outside my namespace.
Now, it's linked and works but my android app is crashed, I think it's a different issue :{@Montjet Oh sorry I should have mentioned that. You can't have a namespace around Q_INIT_RESOURCES.
It's covered in the Qt docs on using resources in a shared object. I didn't think to mention it.
The crash is more than likely completely unrelated, so we'll consider this solved for now. Glad at least 1 part of your problem is over. :)
