Preparing for Crystal sync 2019-01-31

I’m sorry, I made a copy+paste error in the CMakeLists.txt of fmi_adapter in this release: The shared library ( is installed in crystal/lib/fmi_adapter (just as the node executable) rather than crystal/lib. Meanwhile, it is fixed:

@nuclearsandwich This type of error is detected neither by local unit tests nor on the build farm? What do you think, should I open an issue on for that?


The unit tests can’t detect the bug because they use the executable from the CMAKE_BINARY_DIR and that binary uses a full RPATH to the library.

When you are installing the executable CMake is clearing full RPATH to instead rely on LD_LIBRARY_PATH. And since the path <prefix>/lib/fmi_adapter is not listed in that environment variable it will fail to find the library.

As a consequence also the ros_buildfarm has no way to check for this.

If you would like add tests covering your installed packages you could create a separate package test_fmi_adapter which depends on fmi_adapter and contains tests which ensure that the installed package fmi_adapter is working as desired. (In the release process using bloom you usually want to skip the test_fmi_adapter package from being released to avoid a Debian package being created for it. This can be configured in the release repository.)


Thank you for the detailed explanation, @dirk-thomas. With it, I was able to reproduce the bug from a second package (the existing fmi_adapter_examples package), but only when not using colcon’s --symlink-install option. (Many thanks to @karsten for the hint on this option.)
