APAR status

• Closed as program error.

Error description

• When compiling .c files with dependency file generation, the
  dependency file is created with permission -rw-rw-rw by
  default, plus the effect of umask. For .cpp files, however, the
  files are always created as -rw-r--r--.
  
  This creates problems during software development
  collaboration, since people in the same group cannot write over
  the dependency files created by other people in the group.
  
  $ umask 0
  $xlc_r -MF t1.d -qmakedep=gcc test.c
  $xlC_r -MF t2.d -qmakedep=gcc test.cpp
  $ll *.d
  -rw-rw-rw-    t1.d
  -rw-r--r--      t2.d
  

Local fix

• Manually modify file permission using chmod command.
  

Problem summary

• PROBLEM DESCRIPTION: Dependency files for source compiled as
  C++ is created without write permissions for 'group' and
  'other'
  
  USERS AFFECTED: Users of make dependency files requiring write
  permissions for 'group' or 'other' using an appropriate umask.
  

Problem conclusion

• The permissions bits are now specified to be 0666 before
  application of the umask by the system.
  

Temporary fix
