Support Software

Perl -- the perl binary should be in your path. Perl is used for dependency generation and also for building the state tracking system. Available on the web at http://www.perl.com.
Python -- the python binary should be in your path. Python is used for generating code in the client DLL and server. Available on the web at http://www.python.org
GM -- if compiling with Myrinet support. Available on the web at http://www.myri.com
Cygwin -- (Windows Only) Provides basic Unix command line tools for Windows. Required only for building WireGL from command line. Vis Studio 6 does not require Cygwin to build the source. Available on the web at http://www.cygnus.com/cygwin.

Environment variables

The following environment variables must be set to build WireGL from the command line. If building from Visual Studio 6, none of these are required:

WORK_ROOT	Set to the full path of the "work" directory in the above structure. Note: use forward slashes ("/") as directory separator in Windows, i.e. "c:/work" not "c:\work"
ARCH	WINDOWS ONLY -- set to "WIN_NT".
MAKE_MODE	WINDOWS ONLY -- set to "unix"

Building

To build WireGL from the command line, go to the "wiregl" directory, and run GNU make (by typing "make" or "gmake").

A Visual Studio 6 workspace file (wiregl.dsw) is also provided for compiling under Windows. Load the workspace file and select "Batch Build" from the Build menu. Select either the Debug or Release versions and press build.

Myrinet Support

Myrinet GM support is disabled by default. To enable GM, uncomment the GM_SUPPORT line in the Makefile located in the util directory for building using the make system. To enable GM in the Visual Studio project file, select the GM configuration under Build,Batch Build menu option. Myrinet drivers are available at http://www.myri.com
