Building instructions for GEL under Visual Studio 7.1 and 8 (2003 and 2005)
1. Project configuration
We use MPC to maintain .sln and .vcproj files, since the format of these files changes with each new version of Visual studio. The average GEL-user need not bother with this, since .bat files have been created to ease the use.
More info on MPC can be found on:
http://www.ociweb.com/products/mpc
Note that Perl must be installed to use MPC.
2. Subsetting
The use of MPC allows relatively easy creation of subsets of GEL. An example subset is created using the file build_vc71_solution_CGLA.bat creates the subset .sln and vcproj files using MPC and the Perl script makefiles/CGLA.pl which deletes all non-CGLA source code from GEL.
3. Build Configurations
Each project contain three configurations: Debug, Release and
Install. Debug and Release have the usual functionality, while Install
is special.
We assume, that once GEL is installed, it should be used without
adding the source and header files to the particular project.
Therefore we install GEL in an outside directory defined by the
environment variable GELEXT. In the configuration, this is done by
setting the Target Directory to
$(GELEXT)\lib\windows
and, as a post-build event, all header files are copied to
$(GELEXt)\include
The GELEXT variable should be the path where all 3rd party lib and
header files are stored (like /usr/local/ on a *NIX system)
