# Installation Guide for VMS

This is how to get the sources for www and recompile them. You need to do this if you have a shareable library incompatibility with the distributed executable.

## Changing to a new TCP/IP version

Do this bit if your TCP/IP system is not SRI/Multinet, DEC/UCX or whatever they call it now, or Wollongong TCP/IP.

You might need to change something in sysdep.h which is the system specific include file, and in descrip.mms, the makefile. If you do, please mail me the changes.

Look for all occurences of "MULTINET", "UCX" or "WIN_TCP" and add a "CMU_TEK" or whatever where necessary. The same goes for decsrip.mms. This will need to pass the CMU_TEK option onto the c compiler in the CFLAGS macro, and also use different libraries for the link. Changes to other files will probably not be necessary.

[The program uses the socket library in a very standard way - no tricks. You just have to get the include files from the right place and fix the macros for NETREAD etc to whatever CMU-TEK calls the socket read() function. It can't call it read() because that's in the VMS unix library already for file access. You notice that under some systems the read does a socket_read or a real read depending on whether the socket number is small (unix) or large (VMS channel=socket). I don't know what CMU-TEK does but I'm interested to know If you don't know either, try compiling for say WIN_TCP and see what's undefined and mail me] If you do this, let me know how you get on, please!

## Compiling

One way, if you have a unix (sultrix?) system with DECnet is to unwrap the tar file on that system.

Then copy WWW/LineMode/src/vms/descrip.mms across to VMS. Edit descrip.mms so that all the references to $(U)"/userd/tbl/hypertext are changed to point to the decnet address of the files you have unwrapped on the unix system. Then run mms with /macro=(u=HOST::, cmu_tek=1) -- whatever your unix HOST is -- and it will pickup all the files from your unix system.

The other way is to uncompress/untar it on under VMS, if you have a tool to do that, and just run mms/macro=(cmu_tek=1).
