in thread installing pgplot on cygwin

Did you put the pggw stuff in /usr/local/pgplot? The libpgplot.a in that references GWgetrgb, which is actually provided in libGrWin.a and libGrWin0.a. I don't remember the latter two libraries being linked; you might try adding a -lGrWin switch.

    I installed the pggw0999b-cygwin.exe into my
    c:/cygwin/user/local
    I copied the *.a files to the /usr/local/lib
    (my cygwin didn't have a /usr/lib directory)
    and the *.h files to the /usr/include

    I added the following to the Cygwin.bat file...

    SET PATH=C:\CYGWIN\BIN;C:\CYGWIN\USR\LOCAL\PGPLOT;C:\CYGWIN\GRWIN;%PATH%
    SET PGPLOT_DIR=C:\CYGWIN\USR\LOCAL\PGPLOT

    I am sorry but you will have to baby step me here
    how do you add the -lGrWin switch


    thanks Penny

    Look this may be beyond me unless it is a relative simple fix.
    Thanks again for looking at it. It is good to know that I did follow the instructions properly
    and maybe there is a bigger problem


    Finally got it working...

    Thanks to help from Tsuguhiro TAMARIBUCHI the author of GrWin
    Basically I got Cpan Pgplot module working with GrWin in Cygwin
    by making the following changes to the perl Pgplot module Makefile
    line 37
    LDDLFLAGS = -s -L/usr/local/lib
    change to
    LDDLFLAGS = -s -L/usr/local/lib -Wl,--subsystem,console -mwindows
    I was advised to to use the linker options. -Wl,--subsystem,console -lcpgplot -lpgplot -lGrWin -mwindows
    or
    -Wl,--subsystem,windows -lcpgplot -lpgplot -lGrWin -mwindows
    depending on your application being a console application or a windows application.
    in lines 277-279
    I included the -lGrWin Libary
    EXTRALIBS = -L/usr/local/pgplot -L/usr/local/pgplot -L/usr/local/lib -lcpgplot -lpgplot -lGrWin ......
    LDLOADLIBS = -L/usr/local/pgplot -L/usr/local/pgplot -L/usr/local/lib -lcpgplot -lpgplot -lGrWin ......
