< GD library, Graphics, Library to create graphs from programs   Installation  M Just execute @make to build the library. This checks for available compilers  H as well as MMS/MMK and uses them for the build if available. Upon first G invocation make will generate a template vmslib.dat, which needs to be  , tailored to reflect your local installation.   J Minimum requirement for using the current version of the GDlib is to have M installed Libpng and Zlib. Additional features of the library can be used if  L the following libraries are available too: Jpeglib, Freetype 2, and XPMlib. N All information on these libraries needed by the build procedure is collected F in the file vmslib.dat. The format of this is documented here. If not K available make.com will create a template vmslib.dat upon first invocation  < which needs to be tailored to match the local installation.     
 Build options     E Make.com currently accepts the following options in arbitrary order:     DEBUG C Build the library with debug information and without optimization.  
 lopts=<value> 9 Options to pass to the link command e.g. lopts=/tracback  
 ccopt=<value> 9 Options to pass to the C compiler e.g. ccopt=/float=ieee   LINK. Do not compile, just link GD example programs  CC=<DECC||VAXC||GNUC> K Force usage of the given C compiler over the intrinsic selection (which is  " DEC C, VAX C, and finally GNU C).    Package contents    J The main result of the compilation ist he object library libgd.olb, which H other applications need to link against.
