I am working on a Qt Project that's based on cmake. The Qt version is 5.7, Ubuntu 14.04. The error I am getting is:
QQmlApplicationEngine failed to load component
qrc:/main.qml:-1 File not found
The CMakeLists.txt is:
file(GLOB_RECURSE UI_FILES *.ui)
file(GLOB_RECURSE CODE_FILES *.cpp *.h)
qt5_wrap_ui(UI_HEADERS ${UI_FILES})
qt5_add_resources(RESOURCE_FILES ../resources/resources.qrc)
set(SOURCES
assets/assets.qrc
icons/icons.qrc
qml/qml.qrc)
include(../vendor/CMakeLists.txt)
if (WIN32)
set(WINDOWS_RES_FILE ${CMAKE_CURRENT_BINARY_DIR}/resources.obj)
if (MSVC)
add_custom_command(OUTPUT ${WINDOWS_RES_FILE}
COMMAND rc.exe /fo ${WINDOWS_RES_FILE} resources.rc

)
else()
add_custom_command(OUTPUT ${WINDOWS_RES_FILE}
COMMAND windres.exe resources.rc ${WINDOWS_RES_FILE}

How do I remove this error from the project?

Answer 1

You can use QDirIterator to double check what resources the application contains. For example in main():
QDirIterator it(":/", QDirIterator::Subdirectories);
while (it.hasNext())
qDebug() << it.next();
Without knowing how Qt resource handling works with CMake, I'd say the following lines look like the culprit.
qt5_add_resources(RESOURCE_FILES ../resources/resources.qrc)
set(SOURCES
assets/assets.qrc
icons/icons.qrc
qml/qml.qrc)
Why is one .qrc added with qt5_add_resources(), whereas the others are added to SOURCES?
