Larry,

What I am trying to do is guild a library for working with images called GD.
It is for dynamically creating images, and I got it from:
http://www.boutell.com/gd/

The libraries and order that I am using is:
LIBS=-lfreetype -lgd -lz -ljpeg -lpng -lcygwin

I have resolved most of the issues now, but now I seem to be getting an 
error about a DLL linkage?

Here is the cygwin1.dll that I am using.
where cygwin1.dll
D:\cygwin\bin\cygwin1.dll

Here is the current error that I am getting.

/source/gd-2.0.1 >make install
MAKE Version 5.2  Copyright (c) 1987, 2000 Borland
         rm -f libgd.so.2.0.0 2>/dev/null
The system cannot find the path specified.
         ld -shared -o libgd.so.2.0.0 gd.o gd_gd.o gd_gd2.o gd_io.o gd_io_dp.o
gd_io_file.o gd_ss.o gd_io_ss.o gd_png.o gd_jpeg.o gdxpm.o   gdfontt.o

/usr/lib/libcygwin.a(_cygwin_crt0_common.o)(.text+0xe6): undefined reference to
`GetModuleHandleA AT 4'

** error 1 ** deleting libgd.so.2.0.0

Thanks,

Matt
