- First use the last version of grx, grx244 at present, you can obtain it
from the homepage

http://www.gnu.de/software/GRX/

- Download the zip file from the download page on this site in some temp directory

- then:

cd c:\djgpp                     (if that is your root djgpp directory)
unzip32 c:\temp\grx244s.zip

it will unzip into the directory c:\djgpp\contrib\grx244

- You need to compile the library and the test programs.
Read the readme file in the c:\djgpp\contrib\grx244 directory.

- In summary you have to
       edit makedefs.grx (including in particular INCLUDE_GPC_SUPPORT=y)
cd c:\djgpp\contrib\grx244
make -f makefile.dj2

- then install with

make -f makefile.dj2 install
make -f makefile.dj2 install-fonts
make -f makefile.dj2 install-info

- then switch to the pascal subdirectory to run the tests
(they have been compiled with the library if you run make
from the grx244 root directory instead of the src subdirectory)

- for use into your programs you should know that two import units
have been installed into the c:\djgpp\units directory: grx.pas
for native grx programming, graph.pas for Borland BP emulation.

So in your gpc programs include a uses clause e.g.
uses grx;
and compile with the compilation option
gpc myprog.pas -o myprog.exe --automake --unit-path=c:/djgpp/units

(or put a copy of grx.pas in the same directory as myprog.pas and omit
the --unit-path)

Good luck
(I use all this daily without problem)
