Why does my application require libQt6OpenGLWidgets.so

Perdrix

I don't use OpenGL so why does that library get linked into my application?

Hi,

What are the modules you are using ?

Perdrix

I was specifying:

find_package(Qt6 6.8 REQUIRED COMPONENTS Core Gui Widgets Network Charts LinguistTools)

and had to change that when ldd told me the executable needed both DBus and OpenGLWidgets even though I include no headers for either in my code and didn't explicitly link with then either:

target_link_libraries(DeepSkyStacker PRIVATE
    Qt6::Core
    Qt6::Gui
    Qt6::Widgets
    Qt6::Network
	DeepSkyStackerKernel
    ZClass
)

I suppose it is possible that one of my other dependencies pulled in the OpenGLWidgets stuff, but I'd be very surprised.

target_link_libraries(${PROJECT_NAME} PRIVATE Boost::container)
target_link_libraries(${PROJECT_NAME} PRIVATE Exiv2::exiv2lib)
target_link_libraries(${PROJECT_NAME} PRIVATE expat::expat)
target_link_libraries(${PROJECT_NAME} PRIVATE libraw::raw_r)
target_link_libraries(${PROJECT_NAME} PRIVATE TIFF::TIFF)
target_link_libraries(${PROJECT_NAME} PRIVATE ZLIB::ZLIB)

It might be the charts module that triggers this dependencies.

What does DeepSkyStackerKernel use ?

Perdrix

No much apart from QImage and QPixmap

Silly question but did you do a full rebuild since you changed the CMakefile ?
AFAIK, it should not be need but sometimes...
