[gentoo-dev] Use --with-sysroot configure switch when cross-compiling

[Gerhard Bräunlich]

Dear gentoo devs
In August I reported the following bug:
https://bugs.gentoo.org/show_bug.cgi?id=590404
James Le Cuirot suggested to automatically use the --with-sysroot 
configure switch when cross-compiling (

checking for its presence in --help like for --docdir).

I proposed a patch in the above bug report for phase-helpers.sh. However 
as the current version of phase-helpers.sh calls "
___eapi_econf_passes_", I suppose that we should add a corresponding 
___eapi_econf_passes_--with-sysroot function in eapi.sh.

There I am not sure which EAPIs are allowed to be modified.

What do you think?

Sorry for not replying to the bug report recently, I'm battling on many
fronts. That function would not make sense unless --with-sysroot is
introduced into PMS. We could do that but many existing ebuilds would
fail to cross-compile and with hundreds of ebuilds still sitting at
EAPI 0, we could be waiting a long time for fixes. I noted that while
PMS does say which options you must pass, it doesn't say that you
cannot pass additional ones. I've tested it a lot and I've never seen
--with-sysroot break any ebuilds, while it fixes very many, so I
believe it would be safe to pass this option on all EAPIs. We would
probably only pass it when SYSROOT!=/ anyway so it wouldn't affect many
users. This is more or less what you did in your own patch. We are
discussing exactly what influence SYSROOT should have on Portage in
bug #573306 so that we can cement this into EAPI 7 but I believe we can
still rely on SYSROOT in earlier EAPIs when it's set to the same value
as ROOT.

[gentoo-dev] RFC: Future EAPI version operator changes

[Michał Górny]

Hi, everyone.

Following my previous RFC wrt version operator problems, I'd like to
start the second part of the discussion: how to improve version
operators in a Future EAPI?

I've collected various ideas on operator changes on a wiki page [1].
I've tried to stay open-minded and cover every possibility, even though
I doubt some of them would be even considered.

I should warn you that some of the solutions are interlinked to each
other, and you probably need to look through the whole page first
before starting to construct an opinion. For example, specific
solutions to most of the problems depend on whether we enable version
ranges and in which form.

I think we should start by loosely discussing the various ideas
on the wiki page. Feel free to also point out any missing ideas
or remarks that would be useful there.

So, what are your comments?

Re: [gentoo-dev] RFC: Future EAPI version operator changes

[Jan Chren (rindeal)]

First of all thank you for the research and wish you a good luck in
making the changes happen.


## Reordering to PACKAGE OP VERSION

 [ ] [:]

is more sane than

 [:] [ ]

even though it's not so "hierarchically correct".

Thus instead of writing

dev-foo/bar:4===4.1

one would write

dev-foo/bar==4.1*:4=

which is nicely readable.

But in case the box brackets notation gets incorporated (as in Exheres),

 [:] [[ ]]

is the way to go.


## Version ranges

dev-foo/bar:0[(>=2 && <4) || (>=6 && <10)][baz?]

looks the most promising to me as it allows to include and exclude any
number of ranges.


## Things not included

### Comments/annotations

Currently, there is no way to put inline comments to *DEPEND, IUSE,
..., thus the only supported way is to put the comments above the
specification and somehow tell the reader what part of the
specification is the comment about. For 3-4 deps it's acceptable, for
20+ it's insane and thus no one does it, losing valuable information
about the reasoning by doing so.

Mu current workaround is:

DEPEND_A=(
   # comment
   "cat/pkg..."
   "|| ("
  # comment
  "cat/foo"
  "cat/bar"
   ")"
)
DEPEND="${DEPEND_A[*]}"


### Logical operators for groups

 OR

Currently there is no way to specify:

foo||bar? (
  cat/pkg
)

and one has to copy&paste a lot:

foo? (
  cat/pkg
)
bar? (
  cat/pkg
)

 AND

AND can be specified via nested groups:

foo? (
  bar? (
cat/pkg
  )
)

but this syntax is verbose and not explicit.

foo&&bar? (
  cat/pkg
)

would be much more readable.

OK. No problem. Tanks.

I've proposed to revert the change in behavior because we've had too
many problems with it:
