Because the Sun Studio 12 software product components and man pages are not installed into the system directories /usr/bin/ and /usr/share/man, you might need to change your PATH and MANPATH environment variables to enable use of the Sun Studio 12 software. You do not need to change your paths if:
You did not previously install Sun Studio 11 software on your system.
The response to the command/usr/bin/version is Sun Studio 12 software.
On Solaris platforms, add the path /installation_directory/SUNWspro/bin to your PATH environment variable. On Linux platforms, add the path /installation_directory/sunstudio12/bin to your PATH environment variable. If you have previous versions of Sun Studio, Sun ONE Studio, or Forte Developer software installed, add the path before the paths of the previous installations.
On Solaris platforms, add the path /installation_directory/SUNWspro/man/ to your MANPATH environment variable. On Linux platforms, add the path /installation_directory/sunstudio12/man/ to your MANPATH environment variable.
