First of all, thank you for responding Larry

Oh I know.  This is the Windows PC version (should have stated that
earlier).  OpenInventor has a freeware Linux version and a Windows PC
version distributed by TGS.  The version I'm using is the Windows PC version
which has libraries that work with Visual C++.  I just don't know if Cygwin
can use VC++ type library binaries.  I don't recall the format of Visual C++
objects anymore (OMT?).  It's a been a bit.

OK... that's good news.  I wonder what I have to do to link them.  What I'm
doing now for instance is this:

g++ -O  -g C:/Cygwin/home/root/bin/myApp myApp.o graphics.o
/usr/lib/InvSV110.lib /usr/lib/DataViz400.LIB /usr/lib/INV400.LIB /usr/lib/
DataViz400D.LIB /usr/lib/INV400D.LIB /usr/lib/DataVizW400.LIB
/usr/lib/INVU400.L
IB /usr/lib/DataVizW400D.LIB /usr/lib/INVU400D.LIB /usr/lib/DialogViz100.LIB
/us
r/lib/INVW400.LIB /usr/lib/DialogViz100D.LIB /usr/lib/INVW400D.LIB
/usr/lib/Hard
Copy400.LIB /usr/lib/IVF400.LIB /usr/lib/HardCopy400D.LIB
/usr/lib/IVF400D.LIB /
usr/lib/HardCopyW400.LIB /usr/lib/IVvr400.LIB /usr/lib/HardCopyW400D.LIB
/usr/li
b/Ivvr400D.LIB -L
C:/Cygwin/home/root/lib -lm -lpthread -lGLU.dll -lGL.dll -lG
Lw -lg2c

Is there a switch that I need to use for linking windows .LIB files?  I'm
getting lots of undefined references in the Inventor code (included headers)
letting me know that I'm not linking the libraries (at least that's
typically the problem when that happens).

Thank You again!
