I finally got PySide built for the Mac. It was an effort. When I get a
chance, I'll put together a more coherent set of notes. But for now, here
are the changes I needed to make to get it built.
* Because the generator was picking up the wrong atomic_*.h system-specific
headers, I had to remove the ones I didn't want picked up from the Qt
includes directory. Maybe these should just be ignored by the generator
alltogether, or figure out how to get the generator to pick up the header
for the correct architecture....
* QtCore will build fine, but QtGui complains about not being able to find
the Qt headers for some reason. I had to add
set(QT_INCLUDE_DIR "/usr/local/Trolltech/Qt-4.5.2/include")
to the top level CMakeLists.txt for it to build. I can re-look into this,
because PySide should build using only what's available from the binary
install of Qt on OSX (which means CMake should find things in the
/Library/Frameworks directories).
* QtUiTools doesn't get installed as a Framework on OSX, so I had to add:
set(QT_QTUITOOLS_INCLUDE_DIR
"/usr/local/Trolltech/Qt-4.5.2/include/QtUiTools")
in order for CMake to find those headers. Like the previous issue, a better
solution should be found that rely only on the binary install of Qt.
* There are some unsupported linker flags being used in
CMAKE_CXX_FLAGS_RELEASE in the top level CMakeLists.txt, so I had to take
those out by removing the -Wl,* flags:
set(CMAKE_CXX_FLAGS_RELEASE "-Wall -fvisibility=hidden
-fvisibility-inlines-hidden -Os -finline-limit=600 -ffunction-sections
-fomit-frame-pointer -fno-default-inline -fconserve-space
-fno-enforce-eh-specs -fno-threadsafe-statics -fno-implicit-inline-templates
-DNDEBUG -DBOOST_PYTHON_NO_PY_SIGNATURES")
* boost::python is having trouble with some class methods that return
Qt::Handle, because it's an alias for void*, and there is no return policy
defined for void*. For now, I just had the scanner ignore those methods by
adding the following.
data/typesystem/typesystem_core.xml:
<rejection class="QThread" function-name="currentThreadId"/>
data/typesystem/typesystem_gui.xml:
<rejection class="QFont" function-name="handle"/>
data/typesystem/typesystem_network.xml:
<rejection class="QSslCertificate" function-name="handle"/>
<rejection class="QSslKey" function-name="handle"/>
data/typesystem/typesystem_opengl.xml
<rejection class="QGLColormap" function-name="handle"/>
<rejection class="QGLPixelBuffer" function-name="handle"/>
* QtGui: qx11_info is not available on OSX or windows:
PySide/QtGui/CMakeLists.txt
Comment out the qx11_wrapper lines:
#${CMAKE_CURRENT_BINARY_DIR}/${BINDING_NAME}/QtGui/qx11info_wrapper.cpp
#${CMAKE_CURRENT_BINARY_DIR}/${BINDING_NAME}/QtGui/qx11info_wrapper.hpp
* QtGui: Unknown linker option: --reduce-memory-overheads
PySide/QtGui/CMakeLists.txt
Comment out the "LINK_FLAGS" line:
#set_target_properties(QtGui PROPERTIES PREFIX "" LINK_FLAGS
"-Wl,--reduce-memory-overheads")
* QtOpenGL: Missing link to QtGui library (causes undefined QWidget
symbols).
PySide/QtOpenGL/CMakeLists.txt
Add ${QT_QTGUI_LIBRARY} to target_link_libraries.
target_link_libraries(QtOpenGL
${Boost_PYTHON_LIBRARY}
${PYTHON_LIBRARIES}
${QT_QTCORE_LIBRARY}
${QT_QTGUI_LIBRARY}
${QT_QTOPENGL_LIBRARY}
pysidebase)
* QtHelp: Missing link to QtGUi library.
PySide/QtHelp/CMakeLists.txt
Add ${QT_QTGUI_LIBRARY} to target_link_libraries.
target_link_libraries(QtHelp
${Boost_PYTHON_LIBRARY}
${PYTHON_LIBRARIES}
${QT_QTCORE_LIBRARY}
${QT_QTGUI_LIBRARY}
${QT_QTHELP_LIBRARY}
pysidebase)
* QtScriptTools: The "ugly workaround" in QtScriptTools CMakeLists.txt does
not work for OSX.
PySide/QtScriptTools/CMakeLists.txt
Replace
set (QT_QTSCRIPTTOOLS_INCLUDE_DIR ${QT_QTSCRIPT_INCLUDE_DIR}Tools)
set (QT_QTSCRIPTTOOLS_LIBRARY -lQtScriptTools)
With
set(QT_QTSCRIPTTOOLS_INCLUDE_DIR
"/Library/Frameworks/QtScriptTools.framework/Headers")
set (QT_QTSCRIPTTOOLS_LIBRARY "-framework QtScriptTools")
* QtScriptTools: Missing link to QtGui and QtScript libraries.
PySide/QtScriptTools/CMakeLists.txt
Add ${QT_QTGUI_LIBRARY} and ${QT_QTSCRIPT_LIBRARY} to target_link_libraries.
target_link_libraries(QtScriptTools
${Boost_PYTHON_LIBRARY}
${PYTHON_LIBRARIES}
${QT_QTCORE_LIBRARY}
${QT_QTGUI_LIBRARY}
${QT_QTSCRIPT_LIBRARY}
${QT_QTSCRIPTTOOLS_LIBRARY}
pysidebase)
* QtUiTools: Missing link to QtUiTools library.
OSX doesn't install QtUiTools as a Framework (because QtUiTools is a static
library and not a shared library). This also means that (as far as I know)
Qt does not include the QtUiTools library with the binary installation of Qt
on OSX!
QtUiTools needs to be manually added to the libraries to link:
PySide/QtUiTools/CMakeLists.txt
Add the QtUiTools library.
set (QT_QTUITOOLS_LIBRARY "-L/usr/local/Trolltech/Qt-4.5.2/lib -lQtUiTools")
* QtGui creates libQtGui.so, but the install is trying to copy QtGui.so.
PySide/QtGui/CMakeLists.txt
Change
install(FILES ${CMAKE_CURRENT_BINARY_DIR}/QtGui.so
To
install(FILES ${CMAKE_CURRENT_BINARY_DIR}/libQtGui.so
