Have you been looking where/how to properly set the DEBUG preprocessor macro in Xcode?
|

#ifdef DEBUG writeDebugOutput(); #endif |
Allegedly the DEBUG should be set automagically when using the debug profile. For me however that didn’t work out. Here is how to do it manually.
Compile all your ROS packages as usual and make sure there are no more errors left
|

cd ~/ros_catkin_ws catkin_make |
Because having too many packages in Xcode can be a bit overwhelming, I recommend to install all the unused packages to /opt/ros/indigo:
|
1 |
catkin_make install -DCMAKE_INSTALL_PREFIX=/opt/ros/indigo |
Remove the build, devel and the unneeded stuff from src
|
1 |
rm -rf build devel |
Then generate a Xcode project by:
|
1 |
catkin_make -G"Xcode" |
you may have to do this every time you add a new package or add files to a package so define an alias:
|
1 |
alias catkin_make_xcodeproject='catkin_make -G"Xcode"' |
Define an alias for starting ROS from the console in your .zshrc:
|
1 |
alias xcode_ros='open /Applications/Xcode.app ~/ros_catkin_ws/build/Project.xcodeproj' |
Start ROS from the console so that it gets its correct environment
|
1 |
xcode_ros |
If you get an error like this after linking:
|
1 2 3 |
dyld: Library not loaded: libcv_bridge.dylib Referenced from: /Users/tatsch/ros_catkin_ws/devel/lib/pixel_slam/Debug/slam Reason: image not found |
Click Product->Scheme->Edit Scheme->Run „Target Name“->Environment Variables
and add DYLD_LIBRARY_PATH /opt/ros/indigo/lib
