If you wish to correctly compile your OCL application, then the following should be used:

• if you are using the project templates and WorkFrame that come with Visual Age, then
  1. click on Tools
  2. make certain that View is set to Actions
  3. expand the Compile subtree
  4. right-mouse-click on C++ Compiler
  5. select File Options
  6. select the Object tab
  7. select the Multithread option for Library selection (this sets the /Gm+ flag)
  8. click on OK
  9. close the tools setup
  10. regenerate the makefile and recompile

• if you are compiling from the command-line, or using your own makefiles, then
  1. use the command icc.exe /Gm+ /C <other optional compiler flags> myfile.cpp
