C++ Example Federates don't work on *nix systems

[timpokorny]

Summary

When attempting to compile and run the C++ example federates, they do not appear to work on Mac OS X (or Linux I believe). There is an rpath issue, with the following error being given when you attempt to run the example federate in GDB (compiling works fine):

(gdb) run
Starting program: /Users/tim/Developer/workspace/opensource/portico/codebase/dist/portico-2.0.1/examples/cpp/hla13/example-federate 
dyld: Library not loaded: @rpath/libjvm.dylib
  Referenced from: /Users/tim/Developer/workspace/opensource/portico/codebase/dist/portico-2.0.1/lib/gcc4/libRTI-NG64.dylib
  Reason: image not found

Program received signal SIGTRAP, Trace/breakpoint trap.
0x00007fff5fc01075 in ?? ()

Running the federate outside of GDB just generates a note saying that no JRE could be found and a legacy one will have to be installed.

Environment and Logs

• Portico 2.1.0-beta
• Mac OS X Yosemite (10.10)

  Reproduction Steps

• Build a full sandbox with sandbox.full
• Move into the HLA 1.3 C++ example federate within the sandbox
• Compile the federate with ./macos.sh compile
• Attempt to run the federate with ./macos.sh execute
• Witness the error
• Run under GDB: sudo ggdb -x gdb.env ./example-federate and you will get the rpath error as described above

  Check List

List of example federates/platform combinations to check:

Mac OS X

• [x] HLA 1.3
• [x] HLA 1.3 in GDB
• [x] IEEE 1516e
• [x] IEEE 1516e in GDB

Linux

• [x] HLA 1.3
• [x] HLA 1.3 in GDB
• [x] IEEE 1516e
• [x] IEEE 1516e in GDB

Noticed that I have done some work on this before. On Mac OS X there are now separate gdb.env files for Linux and Mac OS X. Confirm that everything works on OS X. If you run with the platform specific versions, everything is OK (at least on Mac OS X). Will confirm on Linux.

All confirmed on linux. Hooray for past Tim (and boo for him not updating the paperwork).
