Bastians solution seems to have fixed your problem by adding the
gr-blocks library to your linker targets.
But now your error exposes that you didn't link against the gr-runtime.
Are you sure you have something like
set(GR_REQUIRED_COMPONENTS RUNTIME BLOCKS)
and not deleted the RUNTIME component, leaving only
set(GR_REQUIRED_COMPONENTS BLOCKS)
?
could you please share your project (preferably on github or bitbucket
or the like) or at least the CMakeLists (e.g gists.github.com,
pastebin, or the like) ?
Greetings,
Marcus
