This bug appears, when cmake generates the man pages.

What compiler? What OS version? What cmake options?

It doesn't seem to be happening with any of the Jenkins MacOS build configurations.

  • Status changed from New to Closed

I found the problem, when executing g_x2top the already installed version of libmd was loaded, which causes a bus error. So I guess we should increase the so number at some point.

#4 Updated by Roland Schulz over 8 years ago

On Linux this is usually prevented by a correct rpath. According to, Mac OS X has @rpath, @loader_path and @executable_path mechanism. I don't know anything about that, but could it be that the rpath settings are not correct for Darwin?

Also I think we should go ahead an increase the so version now or create a separate bug with a todo list for the release so that this isn't forgotten.
