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
In file included from /home/kohlbrecher/flor_repo/catkin_ws/src/flor_common/flor_interactive_marker_server_custom/src/interactive_marker_server_custom.cpp:68:0:

compilation terminated.
make[2]: *** [flor_common/flor_interactive_marker_server_custom/CMakeFiles/flor_interactive_marker_server_custom.dir/src/interactive_marker_server_custom.cpp.o] Error 1
make[1]: *** [flor_common/flor_interactive_marker_server_custom/CMakeFiles/flor_interactive_marker_server_custom.dir/all] Error 2
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?

In the case of incompletely specified target dependencies you will face issues like the one you describe when building with multiple threads in parallel.

You should open tickets against the packages which lack proper dependencies and try to e.g. compile C++ code before the required message header have been generated.

The How-To should describe how the dependencies must be stated in CMake.

In the case of the posted example message that would be flor_interactive_marker_server_custom.

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.

The link leads to not-found. For Hydro it's found here.
