Processing hints file hints/solaris.pl

Warning: This extension uses C++ and requires that you use the C++ 
	 compiler to compile the XSUB file ( normally just a C compiler
	 is required ). 

	 If your build fails with a plethora of errors, then check
	 two things: 

	 1. That you have defined the correct OS_xxxxx macro for your
	    platform ( see the Perforce API documentation for more info )

	 2. That the correct compilers are being used.

	 3. That you're using the correct build of the Perforce API. 

	 See hints/linux.pl to see how it should be done.


This extension requires the Perforce API in order to be built. If you
do not yet have the API files, then download them from ftp://ftp.perforce.com
before continuing.

Where is the Perforce API to be found: Added P4 libs to -lsocket
Added P4 libs to -lnsl

The test suite needs to know where your Perforce server is. The tests
are non-invasive and no new data will be added to your depot during
the tests
