DYLD_LIBRARY_PATH not loading in gdb-ia on OS X

Hi

Trying out 2017 beta version of Fortran (I also have the previous 2013 ifort version) but I'm having a challenge with  gdb-ia. I have my .bash_profile set so that DYLD_LIBRARY_PATH is set so that on the command line I get 

echo $DYLD_LIBRARY_PATH/libiomp5.dylib

 

/opt/intel/compilers_and_libraries_2017.0.039/mac/compiler/lib/libiomp5.dylib

 
When in gdb-ia I get the following
 

(gdb) set environment DYLD_LIBRARY_PATH /opt/intel/compilers_and_libraries_2017.0.039/mac/compiler/lib

(gdb) run

The program being debugged has been started already.

Start it from the beginning? (y or n) y

Starting program: ~/LMSafe 

dyld: Library not loaded: @rpath/libiomp5.dylib

  Referenced from: ~/LMSafe

  Reason: image not found

 

Program received signal SIGTRAP, Trace/breakpoint trap.

0x00007fff5fc01075 in ?? ()

 

(gdb) 

in gdb-ia show environment gives.. 
 

DYLD_LIBRARY_PATH=/opt/intel/compilers_and_libraries_2017.0.039/mac/compiler/lib

 
 
If I run from 2013’s idb it works (even though I had to manually set the path in idb)
 
(idb) set environment DYLD_LIBRARY_PATH /opt/intel/compilers_and_libraries_2017.0.039/mac/compiler/lib
(idb) run
Program exited normally.
Starting program: ~/LMSafe

any ideas?

apologies for untidy post, the default editor here doesn't seem to handle carriage return properly so I just and pasted from a text editor, looked OK before I posted ;-(

For info I also tried 

install_name_tool -change libiomp5.dylib /opt/intel/compilers_and_libraries_2017.0.039/mac/compiler/lib/libiomp5.dylib ~/LMSafe

otool -l LMSafe

Hello,

if you run it outside the debugger:

$ ~/LMSafe
...will fail because @rpath/libiomp5.dylib is not found.

$ DYLD_LIBRARY_PATH=/opt/intel/compilers_and_libraries_2017.0.039/mac/compiler/lib ~/LMSafe
...will work as libiomp5.dylib is found.

Is my assumption correct?

If so, could you try to link with "-rpath" set to /opt/intel/compilers_and_libraries_2017.0.039/mac/compiler/lib? "otool -l" should show an entry "cmd LC_RPATH" with the proper path set. Does this work then with gdb-ia?

So far I can see the same symptom but once I set the environment in GDB (set environment DYLD_LIBRARY_PATH <path>) it works.

Could you please also try the latest 2017 BETA Update 1 release? This update will be available end of the week.

Best regards,

Georg Zitzlsberger
