OMNotebook fails to simulate on OS X

[Henning Kiel]

Running the "HelloWorld" example from the DrModelica does not work on my OS X (local build from git).
I run OMNotebook from command line without installation: build/Applications/OMNotebook.app/Contents/MacOS/OMNotebook

Running simulations in OMEdit this way works fine.

OMNotebook compiles everything fine (executable is produced in tmp folder), but system() call seems to fail with "interrupted system call" though:

record SimulationResult
    resultFile = "",
    messages = "Failed to build model: HelloWorld"
end SimulationResult;
OMC-ERROR: 
"Error: system(make -j4 -f HelloWorld.makefile) failed: Interrupted system call

Does running setCommandLineOptions("-n=1") in a cell work?

[Henning Kiel]

setCommandLineOptions("-n=1") is accepted and I see that a following simulation uses "-j1" option for make

[Martin Sjölund]

But the simulation still fails?

[Henning Kiel]

yes, it still fails.
Same output except for the "-j1"
plot( x ) afterwards gives a 'false'

[Henning Kiel]

waitpid() returns with EINTR. Solution is to fix SystemImplsystemCall() by repeating waitpid() until anything else than EINTR is received.
