why does compiling on HP fail with notes about s%@LIBXMU_LIB@%-lXmu?
From the Sun -> HP porting guide… “Some of the X include files and libraries are not in /usr/include/X11 and /usr/lib/X11 as you may expect. This is because HP allows support for X11R4 and X11R5 on the same machine. You must modify a configuration file so that the Makefile created by imake looks for these files and libraries in an alternate location. See “Motif and Xt” on page A-5 and “Xaw and Xmu” on page A-6 for details on installation of OSF/Motif, Xt, Xaw and Xmu. … “HP does not ship or support these widget libraries; however, they are widely used for X public domain software. Binaries and header files are available from the Interworks library. Source is available from public domain archives. The name of the binary package in the Interworks library is x8.0s700.tar.Z. You may also be able to locate these files on another machine and copy them to your machine.
