When deploying the program through qt_generate_deploy_qml_app_script using the default CMAKE_INSTALL_LIBDIR (typically 'lib'), the install rpath of the QML module's plugin target will unexpectedly inherit its build rpath.
When I inspect the INSTALL_RPATH property of the plugin target using CMake
get_target_property(plugin_install_rpath myrectmoduleplugin INSTALL_RPATH)
message("INSTALL_RPATH of myrectmoduleplugin is: ${plugin_install_rpath}")
The result is as expected:
INSTALL_RPATH of myrectmoduleplugin is: $ORIGIN/../../../lib
However, when using chrpath to check the rpath of libmyrectmoduleplugin.so, the observed rpath is unexpected:
❯ chrpath --list libmyrectmoduleplugin.so libmyrectmoduleplugin.so: RUNPATH=/home/warindy/Develop/QmlDemo/build/output:/home/warindy/Develop/dep/qt/6.7.0/gcc_64/lib
One workaround is to specify '.' as the value for CMAKE_INSTALL_LIBDIR.
set(CMAKE_INSTALL_LIBDIR "." CACHE STRING "The lib path to use for make install" FORCE)
Then we obtained the correct result.
❯ chrpath --list libmyrectmoduleplugin.so libmyrectmoduleplugin.so: RUNPATH=$ORIGIN/../../../
Please download the attachment and replicate the problem.
When using the default CMAKE_INSTALL_LIBDIR:
# Uncomment the following section to make the program run correctly. # set(CMAKE_INSTALL_LIBDIR "." CACHE STRING "The lib path to use for make install" FORCE) # set(CMAKE_INSTALL_BINDIR "." CACHE STRING "The bin path to use for make install" FORCE)
Build the program, then use chrpath to inspect the results.
cd QmlDemo mkdir build && cd build cmake ../ -GNinja ninja ninja install chrpath --list ./release/qml/myapp/myrect/libmyrectmoduleplugin.so
The outcome should be
libmyrectmoduleplugin.so: RUNPATH=$ORIGIN/../../../
For comparison, set the value of CMAKE_INSTALL_LIBDIR to "."
# Uncomment the following section to make the program run correctly. set(CMAKE_INSTALL_LIBDIR "." CACHE STRING "The lib path to use for make install" FORCE) set(CMAKE_INSTALL_BINDIR "." CACHE STRING "The bin path to use for make install" FORCE)
Rebuild the program and and check the rpath.
cd QmlDemo mkdir buildB && cd buildB cmake ../ -GNinja ninja ninja install chrpath --list ./release/qml/myapp/myrect/libmyrectmoduleplugin.so
The result should be
libmyrectmoduleplugin.so: RUNPATH=/home/warindy/Develop/QmlDemo/build/output:/home/warindy/Develop/dep/qt/6.7.0/gcc_64/lib
