We are working with a pretty large catkin project that compiled just fine for months. Without code changes, we started seeing compile errors after some groovy updates and building from scratch, looking like:

[  2%] Building CXX object flor_common/flor_interactive_marker_server_custom/CMakeFiles/flor_interactive_marker_server_custom.dir/src/interactive_marker_server_custom.cpp.o

compilation terminated.

make: *** [all] Error 2
make: INTERNAL: Exiting with 3 jobserver tokens available; should be 2!
Invoking "make" failed

Noticing that the actual error messages changed when executing "catkin_make" multiple times, I figured there might be some issue with parallel jobs and different timings leading to different errors. Sure enough, when running "catkin_make -j1", the project compiles. Any ideas if there's something on our side making this error appear, or if this is a catkin bug?

Dirk, does this mean that beside the declaration in package.xml and in find_package(catkin ...) a dependency to ${catkin_EXPORTED_TARGETS} or flor_ocs_msgs_generate_messages_cpp has to be declared for every single target in each dependent package that uses the generated headers?!?

Yes, you need a target-level dependency between the target which uses the generated message headers and the target which generates the message headers.
