Hi possible lifesavers,

I am just getting started with ROS, and now having trouble with rosmake. When I try to do rosmake, it will give:

CMake Error at /usr/local/Cellar/cmake/2.8.10.1/share/cmake/Modules/Platform/Darwin.cmake:190 (message):
    CMAKE_OSX_DEPLOYMENT_TARGET is '10.6' but CMAKE_OSX_SYSROOT:

     " "

    is not set to a MacOSX SDK with a recognized version.  Either set
    CMAKE_OSX_SYSROOT to a valid SDK or set CMAKE_OSX_DEPLOYMENT_TARGET to
    empty.
  Call Stack (most recent call first):
    /usr/local/Cellar/cmake/2.8.10.1/share/cmake/Modules/CMakeSystemSpecificInformation.cmake:36 (include)



  -- Configuring incomplete, errors occurred!

Then I configured CMAKE_OSX_SYSROOT to /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk Now, I am getting:

CMake Error at /usr/local/Cellar/cmake/2.8.10.1/share/cmake/Modules/Platform/Darwin.cmake:190 (message):
    CMAKE_OSX_DEPLOYMENT_TARGET is '10.6' but CMAKE_OSX_SYSROOT:

     "10.7"

    is not set to a MacOSX SDK with a recognized version.  Either set
    CMAKE_OSX_SYSROOT to a valid SDK or set CMAKE_OSX_DEPLOYMENT_TARGET to
    empty.
  Call Stack (most recent call first):
    /usr/local/Cellar/cmake/2.8.10.1/share/cmake/Modules/CMakeSystemSpecificInformation.cmake:36 (include)



  -- Configuring incomplete, errors occurred!

which does not really make sense to me now.

So, any ideas?

I have the same issue too ... trying to figure it out.

ok this is what I did, go to /opt/ros/groovy/share/ros/core/rosbuild/public.cmake and comment out line 164 (with the # symbol) that say:

if(APPLE)
   #SET(CMAKE_OSX_DEPLOYMENT_TARGET "10.8" CACHE STRING "Deployment target for OSX" FORCE)
endif(APPLE)

That seems to work for me so far. Maybe @WilliamWoodall might have a better idea.

I have OSX 10.8, ROS Groovy Beta 3, cmake 2.8.10.1, and XCode 4.5.2

Note, I tried changing the 10.6 to a 10.8 since I am using OSX 10.8 and it didn't help. Your line 164 of public.cmake will say 10.6.

I didn't add this line, I'll have to look at the history to see when/why it was introduced. I haven't run into this problem yet.

That should be correct if you did not install it (for some reason) to /opt/ros/groovy. Make sure you do a make clean, that may help.

Just look for the one which is under the path returned by rospack find rosbuild

This is a bug in CMake.

This workaround should not be needed in the future:
