APAR status

• Closed as program error.

Error description

• When -qsmp=omp is specified, the location of the libmassv.a
  library is not passed to the linker and causes a linker
  error. This issue occurs for a non-default installation of the
  compiler.
  
  ===== TESTCASE:
  $ cat masstest.f95
        PROGRAM test
  
           include 'massv.include'
  
           real(kind=8), dimension(500) :: x, y
           integer :: n
  
           n = 500
           x(:) = 1.0d0
           call vexp( y,x,n )
  
        END PROGRAM test
  $
  
  
  ===== ACTUAL OUTPUT:
  $ /home/ndi/bin/xlf95_r -F:mpxlf95_r masstest.f95 -qsmp=omp
  -lmassv ** test   === End of Compilation 1 ===
  1501-510  Compilation successful for file masstest.f95.
  ld: 0706-006 Cannot find or open library file: -l massv
          ld:open(): A file or directory in the path name does not
  exist.
  ld: 0706-006 Cannot find or open library file: -l xlsmp
          ld:open(): A file or directory in the path name does not
  exist.
  $
  
  ===== EXPECTED OUTPUT:
  Should compile clean.
  

Local fix

• Manually add the location of the massv library using the -L
  option.
  

Problem summary

• USERS AFFECTED:
  Anyone using MPI and -qsmp with a non-default installation is
  affected by this issue.
  
  PROBLEM DESCRIPTION:
  In the config file, the smplibraries attribute under mpxl*
  stanzas are missing -L$INST_LOC/usr/lib after an NDI
  installation.
  

Problem conclusion

• The config file has been fixed to include the missing
  -L$INST_LOC/usr/lib after an NDI installation.
  

Temporary fix
