BAD IDEA

Both issues are not the same origine.
The last is really a bug with FGADMIN, nothing to do with multicore
CPU.

Good idea. There is no multi-core issue. Only a fgadmin issue.
We tried to explain, that it is default GNU make behavior to abort a parallel build _immediately_ when any error in any build job is observed. The parallel jobs to build fgfs take the longest (since fgfs is the biggest program in FlightGear). Hence, when any of the small utilities (fgadmin, fgpanel, ...) fails to build, then the fgfs build job won't complete - since the error for the small utility aborts the entire make. With a purely sequential build (make -j1) it is different. We _first_ build fgfs - and only build the utilities afterwards - which is why fgfs completes (built first), even when fgadmin or any other utility fails (built later) in a single-threaded build.

Anyone who doesn't like that default Make behavior should call make with the "-k" (keep going) option, i.e. "make -kj4". This tells GNU make to keep going and at least build all those targets, that are not affected by an error (i.e. when fgadmin fails, fgfs is still completed...).

I wonder if we can educate Cmake a bit more about the build dependency? Or is it really down at the Makefile level?

Hard to say. I just know that there's something wrong about building fgadmin - either with dependencies or the sequence of the libraries. It always fails (same error messages as above) in the OpenSuSE build server project I created - so I had to disable fgadmin there. However, I can build it ok locally - though I have the same OpenSuSE version installed. Unfortunately debugging build scripts on a remote server is painful.

I think I already solved that in fgrun. I will push something and see if Jenkins is still happy.

Yes, that has fixed the FLTK errors (as above). I also had to add a direct ZLIB dependency to make the build work with "SIMGEAR_SHARED":
https://www.gitorious.org/fg/flightgear/commit/f77c6b95fa25c720ac600bbb068b647df9783701
The OpenSuSE build service projects are all "green" now.

Status: Fixed
