Setting up ROS on El Capitan Mac OSX

I mostly followed mikepurvis's notes and plusk01's notes.

Resources I used

brew install qt https://github.com/cartr/homebrew-qt4

how to fix CMake Error at src/qt_gui_cpp

CMake Error at src/qt_gui_cpp/CMakeLists.txt:3 (find_package):
  By not providing "FindQt5Widgets.cmake" in CMAKE_MODULE_PATH this project
  has asked CMake to find a package configuration file provided by
  "Qt5Widgets", but CMake did not find one.

  Could not find a package configuration file provided by "Qt5Widgets" with
  any of the following names:

    Qt5WidgetsConfig.cmake
    qt5widgets-config.cmake

  Add the installation prefix of "Qt5Widgets" to CMAKE_PREFIX_PATH or set
  "Qt5Widgets_DIR" to a directory containing one of the above files.  If
  "Qt5Widgets" provides a separate development package or SDK, be sure it has
  been installed.

Qt5Widgets is not new in Qt (http://stackoverflow.com/questions/23979798/include-qtwidgets-not-working-in-qt-4) so we can ignore / fallback on previous version.

Try 4.4 from the unofficial official tutorial:

More Qt naming issues During the build process, ld complains about -lQtCore et al. In both build_isolated/qt_gui_cpp/sip/qt_gui_cpp_sip/Makefile and >devel_isolated/rviz/bin/sip/rviz_sip/Makefile, the LIBS variable needs the -lQtX flags changed to /usr/local/lib/QtX.framework/QtX (were at end of line).

how to fix ImportError: No module named PyQt5

The PyQt4 way

This one is straightforward, but the fix I used was hacky. I have downloaded PyQt4 (brew install pyqt4-no-webkit), and PyQt5 (brew install pyqt5). I noticed that using python in the console, I could get import PyQt4 to work since qmake --version was telling me I had 4.8.7. So I decided to go into src/python_qt_binding/cmake/sip_configure.py and change from PyQt5 import QtCore to from PyQt4 import QtCore. That seemed to fix this issue. Also in the same file on line 58, changed it to sip_dir = ls ['default_sip_dir'] + '/PyQt4'

The PyQt5 way

i did

brew uninstall pyqt5

then i did

brew install pyqt5 --with-python --without-python3

because ROS kinetic is built with python 2.7

how to fix RuntimeError: the sip module implements API v12.0 but...

RuntimeError: the sip module implements API v12.0 but the PyQt5.QtCore module requires API v12.1

make sure that sip is the same version. mine was not. comapre sip -V with

from sip import SIP_VERSION_STR
print("SIP version:", SIP_VERSION_STR)

how to fix sip: Unable to find file "QtWidgets/QtWidgetsmod.sip"

go to /src/src/qt_gui_core/qt_gui_cpp/src/qt_gui_cpp_sip/qt_gui_cpp.sip and delete the line %Import QtWidgets/QtWidgetsmod.sip.

If this comes back to haunt me later, include the old Qt4 version of QtWidgets (I think it's called like QClass or something

I followed (mikepurvis/ros-install-osx#73 (comment)) and did:

catkin config --install  --install-space ${ROS_INSTALL_DIR} --cmake-args \
    -DCMAKE_FIND_FRAMEWORK=LAST \
    -DCATKIN_ENABLE_TESTING=1 \
   ...

Which seemed to do the trick and fix it.

miscellaneous

rosdep install --from-paths src --ignore-src --rosdistro kinetic -y --as-root pip:yes --skip-keys "libqt5-core libqt5-gui libqt5-opengl libqt5-opengl-dev libqt5-widgets qt5-qmake qtbase5-dev gazebo"

build command 1 (as per unofficial official guide)

./src/catkin/bin/catkin_make_isolated --install -DCMAKE_FIND_FRAMEWORK=LAST -DCMAKE_BUILD_TYPE=Release

build command 2 (as per mikepurvis install script)

catkin config --install --cmake-args \
    -DCMAKE_FIND_FRAMEWORK=LAST \
    -DCATKIN_ENABLE_TESTING=1 \
    -DCMAKE_BUILD_TYPE=Release \
    -DPYTHON_LIBRARY=$(python -c "import sys; print sys.prefix")/lib/libpython2.7.dylib \
    -DPYTHON_INCLUDE_DIR=$(python -c "import sys; print sys.prefix")/include/python2.7
