[Trilinos-Users] [EXTERNAL] Some issue related to rpath in Mac OS X El Capitan

[Sjaardema, Gregory D]

I think that using the CMAKE_MACOSX_RPATH and the CMAKE_INSTALL_RPATH might solve the problem.  If I use it on a Yosemite system, then I don't need to manually set DYLD_LIBRARY_PATH when using shared libraries.  I did something like:

-D CMAKE_MACOSX_RPATH:BOOL=ON \
-D CMAKE_INSTALL_RPATH:PATH=${INSTALL_PATH}/lib \

Not sure if this is the best or correct way to solve the problem, but it seems to work.  Without this, and without setting DYLD_LIBRARY_PATH, I can reproduce the error in locating libsuplib that you show below; with this, the executables run correctly.

Subject: [EXTERNAL] [Trilinos-Users] Some issue related to rpath in Mac OS X El Capitan

Hi,

I'm compiling Trilinos 12.7 (dev) version on Mac OS X 10.11.2 (El Capitan). The compilation and installation for Trilinos goes fine (with the package options I've chosen), however when I try to build Peridigm based on this Trilinos dependency, (after compilation), all unit tests fail for Peridigm. When I check the logs, I see the same type of error over and over again:

dyld: Library not loaded: libsuplib.12.dylib
 Referenced from: /Users/Sai/Box Sync/Peridynamics/Source-Codes/peridigm-versions/peridigm-official/build/test/regression/Contact_Perforation/np3/../../../../scripts/epu
 Reason: image not found

This is an example, but it happens with other binaries (e.g. exodiff) and their dependent libraries. All the libraries are intact in the /usr/local/trilinos/lib directory, but during runtime these libraries don't seem to be loading as need for the executables in the /usr/local/trilinos/bin directory to run.

All tests (100%) failed for Peridigm, so maybe there is some simple fix, but I'm not sure.

In this version of OS X especially, I'm not able to add DYLD_LIBRARY_PATH as an environment variable to allow the linkers to find the appropriate libraries with in the trilinos lib directory. Apparently, SIP (system integrity protection) is a new feature that needs to be turned off before such an environment variable can be set. I'm not sure turning off SIP is a good idea.

Any help with this issue is appreciated.

One more thing to note: I got a lot of the cmake configure script options from another researcher in my group, and the following option was set as shown:

-D CMAKE_MACOSX_RPATH:BOOL=OFF \

Not sure if this has anything to do with it, but just wanted to mention it. I can provide the whole cmake configure script for trilinos I'm using if needed, but for now I think this email is long enough.

Thanks,
Sai
