Hi Rex

Quick question for you on a problem with FindQt5PlatformSupport, which you recently helped to fix in upstream KDE:

http://pkgs.fedoraproject.org/cgit/rpms/kwin.git/commit/?h=master&id=3c1...

Upstream fix: https://git.reviewboard.kde.org/r/126234/ Summary:Fix build with Qt 5.6

I made some progress building Plasma from KDE sources (74 of 81 modules build ok), but kwin is failing -- here's the relevant portion of kwin's cmake.log:

... // All needed KF5... packages were found // Next comes the output of find_package(Threads) -- Looking for pthread.h -- Looking for pthread.h - found -- Looking for pthread_create -- Looking for pthread_create - not found -- Looking for pthread_create in pthreads -- Looking for pthread_create in pthreads - not found -- Looking for pthread_create in pthread -- Looking for pthread_create in pthread - found -- Found Threads: TRUE

// Next some stuff is NOT found, but it's unclear which packages kwin is looking for // and whether any of this is mandatory -- Found PkgConfig: /usr/bin/pkg-config (found version "0.29") -- Found EGL: /usr/lib64/libEGL.so (found version "1.5") -- Found epoxy: /usr/lib64/libepoxy.so -- Wayland: Egl requires Client -- Found Wayland_Client: /usr/lib64/libwayland-client.so (found version "1.10.0") -- Found Wayland_Cursor: /usr/lib64/libwayland-cursor.so (found version "1.10.0") -- Found Wayland_Egl: /usr/lib64/libwayland-egl.so (found version "12.0.3") -- Found Wayland: /usr/lib64/libwayland-client.so;/usr/lib64/libwayland-cursor.so;/usr/lib64/libwayland-egl.so (found suitable version "1.10.0", minimum required is "1.2") found components: Cursor Egl -- Found XKB: /usr/lib64/libxkbcommon.so (found suitable version "0.6.1", minimum required is "0.5.0") -- Could NOT find Libinput (missing: Libinput_LIBRARY Libinput_INCLUDE_DIR) (Required is at least version "1.2") -- Found UDev: /usr/include -- Found Libdrm: /usr/lib64/libdrm.so (found suitable version "2.4.71", minimum required is "2.4.62") -- Could NOT find gbm (missing: gbm_LIBRARY gbm_INCLUDE_DIR) -- Could NOT find libhardware (missing: libhardware_LIBRARY libhardware_INCLUDE_DIR) -- Could NOT find libhwcomposer (missing: libhwcomposer_LIBRARY libhwcomposer_INCLUDE_DIR) -- Could NOT find hybriseglplatform (missing: hybriseglplatform_LIBRARY hybriseglplatform_INCLUDE_DIR)

// Next is an error "Could NOT find Qt5PlatformSupport (missing: Qt5PlatformSupport_LIBRARY" // triggered by cmake/modules/FindQt5PlatformSupport.cmake CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:148 (message): Could NOT find Qt5PlatformSupport (missing: Qt5PlatformSupport_LIBRARY Qt5PlatformSupport_INCLUDE_DIR) (found version "5.6.1") Call Stack (most recent call first): /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:388 (_FPHSA_FAILURE_MESSAGE) cmake/modules/FindQt5PlatformSupport.cmake:89 (find_package_handle_standard_args) CMakeLists.txt:244 (find_package)

// end of cmake.log

My kde/src/kwin/cmake/modules/FindQt5PlatformSupport definitely has the upstream fix:

# Use pkg-config to get the directories and then use these values # in the FIND_PATH() and FIND_LIBRARY() calls find_package(PkgConfig) pkg_check_modules(PKG_Qt5PlatformSupport QUIET Qt5Gui)

Any idea what FindQt5PlatformSupport may be missing? What is meant by Qt5PlatformSupport_LIBRARY? Also, please let me know if you see something under "Could NOT find ..." which you think is mandatory.

Thank you! - Fredy
