rpath issues in runtime libraries on Ubuntu 17.10

[Martin Sjölund]

Tests such as Crane_FMU2_CPP.mos currently fail on Ubuntu 17.10:

messages = "Simulation execution failed for model: cranes_crane_me_FMU
Cannot open library: libomcgc.so.1: cannot open shared object file: No such file or directory
Simulation stopped with error in model factory: Failed loading System library!
/home/marsj/OpenModelica/testsuite/openmodelica/cppruntime/fmu/modelExchange/2.0/OMCppcranes_crane_me_FMU.so

If simCodeTarget is changed to C when compiling the model generated by importFMU, the code works fine. There is something preventing the C++ runtime from working correctly using this code.

[Rüdiger Franke]

This must be a dependency of something linked in from the C runtime.

$ ldd OMCppcranes_crane_me_FMU.so | grep omc
gives under Jessie:

	libOpenModelicaFMIRuntimeC.so => ... /lib/x86_64-linux-gnu/omc/libOpenModelicaFMIRuntimeC.so (0x00007f1704374000)
        ...

$ ldd libOpenModelicaFMIRuntimeC.so
gives:

	linux-vdso.so.1 (0x00007ffd2337f000)
	libomcgc.so.1 => not found

	libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f0d98bf6000)
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f0d9884b000)
	/lib64/ld-linux-x86-64.so.2 (0x00007f0d99829000)
	libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f0d98635000)

Maybe a missing rpath of libOpenModelicaFMIRuntimeC.so that is not critical under Jessie but under Ubuntu 17.10?

[Rüdiger Franke]

This should be fixed asap because otherwise FMI import does not work with the Cpp runtime anymore.

[Martin Sjölund]

I guess because when generating code for the C-runtime, we add rpaths of all library directories that we find, but the Cpp runtime doesn't (?) when it is linking against the C-runtime.

[Martin Sjölund]

See ​PR1967 (which I guess will resolve the issue; I am not on a 17.10 system at the moment).

[Martin Sjölund]

That fixed the issues with libgc, but there still remains one issue:

And nvecserial is not linked in any C-runtime library

Rescheduled to 1.14.0 after 1.13.0 releasee

[Francesco Casella]

Releasing 1.14.0 which is stable and has many improvements w.r.t. 1.13.2. This issue is rescheduled to 1.16.0

[Francesco Casella]

Retargeted to 1.17.0 after 1.16.0 release

[Francesco Casella]

Retargeted to 1.18.0 because of 1.17.0 timed release.
