1) add pcre dependency (for some reason builtin_pcre doesn't work)
2) Disable dependencies that are currently not supported by the
expression. Most users should not need those. These are disabled to
prevent cmake from picking them up from system and causing impurities.
Once there is a user who needs these they will have to update the
expression.
3) disable some OSX detection code that relies on /usr/bin/sw_vers
that chooses c++ library, silences warnings and sets macosx-version-min.
macosx-version-min is already set by nix using MACOSX_DEPLOYMENT_TARGET
environment variable.
root: compile against external gsl
Revert "Revert "root: enable parallel building""
This reverts commit ee1a10ee6b.
ROOT has no problems with parallel build. The problems that caused the
original commit were not related to parallel building.
This seems to have been confusing people, using both xlibs and xorg, etc.
- Avoided renaming local (and different) xlibs binding in gcc*.
- Fixed cases where both xorg and xlibs were used.
Hopefully everything still works as before.
(My OCD kicked in today...)
Remove repeated package names, capitalize first word, remove trailing
periods and move overlong descriptions to longDescription.
I also simplified some descriptions as well, when they were particularly
long or technical, often based on Arch Linux' package descriptions.
I've tried to stay away from generated expressions (and I think I
succeeded).
Some specifics worth mentioning:
* cron, has "Vixie Cron" in its description. The "Vixie" part is not
mentioned anywhere else. I kept it in a parenthesis at the end of the
description.
* ctags description started with "Exuberant Ctags ...", and the
"exuberant" part is not mentioned elsewhere. Kept it in a parenthesis
at the end of description.
* nix has the description "The Nix Deployment System". Since that
doesn't really say much what it is/does (especially after removing
the package name!), I changed that to "Powerful package manager that
makes package management reliable and reproducible" (borrowed from
nixos.org).
* Tons of "GNU Foo, Foo is a [the important bits]" descriptions
is changed to just [the important bits]. If the package name doesn't
contain GNU I don't think it's needed to say it in the description
either.
