from the web page:
"The current version works with GRASS 5.4 and MODFLOW 96 (a recent
version, not the one from 1996) but current work is being done to
develop a new version for GRASS 6.0 and MODFLOW 2000."
"Gmakefile" was the name for GRASS 5 makefiles, to compile a module you
would run gmake5 instead of "make". In GRASS 6 it now uses normal
"make", but this means you need to use a normal Makefile too.
So you will need to port the module to GRASS 6 by writing a new Makefile
First you need to build all of grass from source code to get the correct
build environment set up.
- put the r.gmtg code into the raster/ dir in the grass source.
- copy a Makefile from another raster module into raster/r.gmtg dir.
try to take it from a raster with similar needs (eg vector lib
- edit the Makefile for the module name.
- move r.gmtg.html to r.gmtg/description.html
- run "make" in the raster/r.gmtg dir.
Because it uses FORTRAN, maybe rewriting the Makefile is difficult
without more help and you should just try building it with the old GRASS
5.4 for which it was written? (ie I'm no make expert)
In GRASS 6 there is a new "GEM" system for building modules without
first having to build all of grass yourself:
I see r.gmtg is for ground water flow modelling (MODFLOW). Maybe Soeren
has some new and interesting module for GRASS 6.3 you could try?
