OpenCV3


Qt5::Core (/usr/local/.//mkspecs/macx-clang does not exist)

CMake Error at /usr/local/lib/cmake/Qt5Core/Qt5CoreConfig.cmake:17 (message):
  The imported target "Qt5::Core" references the file

     "/usr/local/.//mkspecs/macx-clang"

  but this file does not exist.

Workaround:
$ brew link --force qt5
$ ln -s /usr/local/Cellar/qt5/5.6.0/mkspecs /usr/local/mkspecs
$ ln -s /usr/local/Cellar/qt5/5.6.0/plugins /usr/local/plugins

QTKit

src/opencv3/modules/videoio/src/cap_qtkit.mm:46:9: fatal error: 'QTKit/QTKit.h' file not found

Workaround: Update OpenCV.
Obtain new version with a script from ROS Wiki page on OpenCV3, then replace original src/opencv3 folder with the contents of the generated opencv.tar.gz, but keep the package.xml.
In case the above script is not available anymore, here is the copy: https://gist.github.com/bgromov/d8c36bc268c8e8bbf65f75dd2854d711
rqt_gui_cpp (and maybe nodelet_tutorial_math)

Check this issue on GitHub.
Solution 1:

Remove build files:

$ rm -rf build_isolated/rqt_gui_cpp
$ rm -rf devel_isolated/rqt_gui_cpp

Rebuild package with -DCMAKE_FIND_FRAMEWORK=LAST flag:

$ ./src/catkin/bin/catkin_make_isolated --install -DCMAKE_BUILD_TYPE=Release -DCMAKE_FIND_FRAMEWORK=LAST --pkg=rqt_gui_cpp
Solution 2 (if the first one did not help):
Have a look at this comment. In essence, the problem is caused by inclusion of the 'wrong' header, another non-system string.h somewhere via uuid/uuid.h.
Install ossp-uuid with brew install ossp-uuid and modify CMake src/cmake_modules/cmake/Modules/FindUUID.cmake file.
Replace:
find_path(UUID_INCLUDE_DIRS uuid/uuid.h)
with:
find_path(UUID_INCLUDE_DIRS ossp/uuid.h)
Note: It might be a good idea to remove whole directories of build_isolated and devel_isolated before if the issues persist.
RViz


Segfault on start:

Check this issue. In short: add #define QT_MAC_USE_COCOA to rviz/src/rviz/ogre_helpers/render_system.cpp somewhere at the beginning of the file, e.g. near or instead of #include <QtCore/qglobal.h>.

Check the following issue. In short: update Ogre to v1.9 and update RViz to latest version. The following versions proved to work fine together: Qt 5.8, Ogre 1.9, RViz 1.12.10.
