[gentoo-user] Decoding portage output

[gentoo-user] Decoding portage output

[Andrew Lowe]

Hi all,
	Can someone please point me to the doco that decodes the following errors:

******************************

Calculating dependencies... done!

!!! The ebuild selected to satisfy "dev-vcs/git" has unmet requirements.
- dev-vcs/git-1.7.8.6 USE="blksha1 cgi curl iconv python threads webdav 
-cvs -doc -emacs -gtk -perl (-ppcsha1) -subversion -tk -xinetd"

   The following REQUIRED_USE flag constraints are unsatisfied:
     cgi? ( perl )

   The above constraints are a subset of the following complete expression:
     cgi? ( perl ) cvs? ( perl ) subversion? ( perl ) webdav? ( curl )

(dependency required by "sys-devel/gettext-0.18.1.1-r3[git]" [ebuild])
(dependency required by "dev-perl/Locale-gettext-1.50.0" [ebuild])

******************************

In particular the "cgi? ( perl )" part.

	Thanks in advance,

To put it simple: if you want to use one of cgi,cvs or subversion,
you'll need to activate the perl useflag too (same fpr webdav and
curl, though that dependency is satisfied).

Hinnerk,
	Thanks for the decode, but where did YOU get the knowledge from? I want 
to understand this, so I don't have to send you an email every time I 
get one of these and need it decoded ;)

Ok, I'll try t explain it:

> The following REQUIRED_USE flag constraints are unsatisfied: cgi? (
> perl )

First: it states that a REQUIRED_USE flag is not set. That means that
some functionality depends on a special useflag.
The next line states, which useflag is the one in question and which
useflag it needs:
You could interprete "cgi?" as "If cgi is set, then test for the
following" and ( perl ) is the flag which is tested.


The rest is simply for more information:

  The above constraints are a subset of the following complete expression:
    cgi? ( perl ) cvs? ( perl ) subversion? ( perl ) webdav? ( curl )

It follows the same syntax, though.

I hope this si helping...

	What I was looking for is a man page/a wiki page/something in the 
Gentoo doco pages, but if that's all there is to it, then thanks for the 
info.

	Regards,

I would have thought that `man 5 ebuild` covered this, if `man emerge` did not. I don't find these documents light reading, however.

Stroller.

man 5 ebuild 

would be the most likely place to start
