[gentoo-dev] The following USE changes are necessary to proceed - Why?

[gentoo-dev] The following USE changes are necessary to proceed - Why?

[Hilco Wijbenga]

Hi all,

I am about to upgrade gnutls. Given the output below:

centaur ~ # emerge gnutls -vp

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild  N     ] dev-libs/nettle-2.4  USE="gmp ssl" 1,051 kB
[ebuild     U  ] net-libs/gnutls-2.12.16 [2.10.5] USE="cxx nettle%*
zlib -bindist -doc -examples -guile -lzo -nls -pkcs11% -static-libs%
-test" 7,000 kB

Total: 2 packages (1 upgrade, 1 new), Size of downloads: 8,051 kB

The following USE changes are necessary to proceed:
#required by net-libs/gnutls-2.12.16[nettle], required by gnutls (argument)
>=dev-libs/nettle-2.4 gmp

So I added the nettle USE flag. I tried both package.use and make.conf
but it doesn't seem to make any difference: Portage keeps giving me
the above output.

Why does portage keep complaining? I'm sure that after the update
everything will be fine but it seems to me that Portage should not
tell me about USE changes if I've already made them?

Cheers,
Hilco

The line above is not prompting you to turn on the nettle use flag, which
appears to already be on.  It's prompting you to add the gmp use flag for
dev-libs/nettle.

Which looks like it's on as well.

In either case -- this isn't gentoo-dev material.

I says nothing about "nettle" use flag. It says:

"Enable the *gmp* flag to the dev-libs/nettle package"

It looks that way, but that's because emerge enabled it automatically to
satisfy the dep (--autounmask is enabled by default these days). The
prompt is there to notify the user that they need to adjust their
configuration files (or use --autounmask-write).

Indeed, forums.gentoo.org would be more appropriate.

Groan ... indeed.

I've disabled autounmask. The error message you get without autounmask
is much clearer. I can see the value of autounmask but the error
(info?) message could be made clearer. (Not that it doesn't contain
all needed information, I obviously wasn't paying enough attention and
the first line threw me.)

>> In either case -- this isn't gentoo-dev material.

No, probably not, it was mostly user error. Still, see above.

Gentoo-user, sure. forums.gentoo.org? No never. MLs are useful, forums
are a pain. But that's a whole different discussion. :-)

I've been tripped up by this in the past.  Can we change the order of the
lines or add some whitespace or indent it or make it a different color or
something?

The "USE changes" really stands out. If we did the same for
">=dev-libs/nettle-2.4 gmp" I think it would be much clearer what's
important.

Yea, he's getting quicker all the time.  I'm scared to even *THINK* of
something new now.  :/
