6. XAS upgrades

preliminary location of this page is at IFCTR

interim     location of this page should be at ITESRE

final       location of this page should be at SAX-SDC

In order to make life easier, it is planned to distribute upgrades to XAS on a module-by-module basis, more than making "full releases".
The following simple cases may be considered :

an existing program is modified and must be recompiled
an existing routine is modified, it must be recompiled and all programs depending on it must be reloaded
similarly if an include file is modified, all modules depending on it must be recompiled or reloaded
a new program and/or a new routine are added
new routines are added but are now called also by old programs

other more complex cases are possible (new libraries ...)

Unix users
The facilities for building XAS under Unix are based on make and the necessary Makefiles are generated automatically by the xasbuild utility.
```

```
- cases 1, 2 and 3 above can be handled installing the new source files and just using option 3 of xasbuild (i.e. a plain make).
- cases 4 and 5 will be handled distributing not only source files, but also updated dependency files (located in $XASTOP/config/Depend). Once all such files are installed, do
  - a run of xasbuild option 2 with the -clean -create options to update the makefiles
  - a run of xasbuild option 2 with default conditions to compile and link
- xasbuild has capabilities to handle more complex cases, but is intended to use these capabilities only at a central site, and distribute updates so that XAS users may just do as above
VMS users
The facilities for building XAS under VMS are extremely primitive and simple, and do not allow automatic management of dependencies so far.

Volunteers to convert xasbuild to VMS Posix make are welcome !
So far individual modules must be recompiled and reloaded manually (some limited facilities are provided in the [.CONFIG] subdirectory). Look at the AAA.README file there, which also contains some hints about handling dependencies manually.

Uploading a XAS upgrade

Filling this form will allow you to upload an ad-hoc kit with all XAS files modified since a given DATE. You may select which SUBSET of data to retrieve, and optionally a target SYSTEM, and you may select the MODALITY of retrieval (you may either view a list of all files modified, or view a page from which you can ftp the files, or will have a tar file made).
This provisionally allows to SEARCH IN the master frozen XAS 1.1 (installed on 27/08/94, now disabled) and to LC's private development versions at IFCTR (the OLD one installed on 14/09/94 now disabled and the CURRENT one installed on 10/04/96, reinstalled on OSF on 11/09/96).
