I've got sources for a program developed under Solaris in ANSI-C. I am told it was developed around 1996-1997. I'm currently struggling with compiling it under a current Ubuntu. I got pretty far and I think only the GUI is still missing. They used a library called guide for this it seems. Does anyone know, if this library still exists somewhere?The relevant parts of the Makefile:INCL    = -I$(GUIDEHOME)/include -I$(OPENWINHOME)/includeLOAD    = -L$(GUIDEHOME)/lib -L$(OPENWINHOME)/libLIB     = -lguide -lguidexv -lxview -lolgx -lX -lmTAG     = -target sun4

As msw says, it appears that your application wants to use the OpenWindows and Xview libraries that were provided in older Sun systems.I believe they're not even around on newer Solaris installs anymore, but the free software projects OpenWindows Augmented Compatibility Environment and The XView Toolkit may provide compatible-enough implementations of these libraries on newer systems.
