REQUIREMENTS file not clear about compilation and priority

[wenzeslaus]

Th file source:grass/trunk/REQUIREMENTS.html​ list General requirements and Optional requirements however, this is not as useful as it could be.

For example, Python is in Optional requirements but you cannot build GRASS documentation and probably other things without it. Moreover, without Python you cannot use any module from scripts and temporal (which is not noted anywhere).

And in the same Optional requirements category there is R language and MySQL libraries which are really optional and not critical at all.

By the way, R is referred as just R at their website (​http://www.r-project.org/) and other places. Description of a package in Ubuntu says GNU R and R. The project for development of this software is sometimes referred as R project (note the lower p), most notably the URL of the web site. However, since R is too short, sometimes, R * environment, R * system or, previously mentioned, GNU R are used.

Hi,

Python now moved to required section in r59504. Also I changed 'R language' to 'R Statistics', so it will be understandable even to people who haven't heard of it before.

what's the story with XDR + MS Windows? is it mandatory/what provides it there?

Replying to hamish:

XDR is no longer a dependency in 7.0. libgis provides XDR functions (they currently only work on systems where floating-point uses IEEE-754 representation, which is roughly everything except for Cray and Vax).

REQUIREMENTS.html updated for XDR in r59854 and r59855.

Can we close this ticket?

[wenzeslaus]

There was several improvements in last two years including Python. An overall review won't harm I guess.

R is still strange. There is no such thing as R Statistics. We also might need a category Recommended (in scale Dependency - Optional - Recommended) because now R at the same level with C++ which is needed e.g. for r.viewshed.

[martinl]

Still relevant?

Bumping it to 7.8
