Bugzilla Bug 173398

I tried to install latest sci-electronics/geda (~amd64).
Installation fails because media-libs/gd was missing.
After "emerge media-libs/gd" and again "emerge geda" all is ok. 
Please note: Old geda was using sci-libs/libgdgeda, which is
obsolete with latest geda!

Thanks for your support. Here is the (first time) output of "emerge geda"

stefan@AMD64X2 ~ $ cat build.log

Reproducible: Always

Steps to Reproduce:
1.emerge geda (on a fresh installation without media-libs/gd)
2.
3.

Actual Results:  
Unable to resolve media-libs/gd to an installed package

Expected Results:  
Installation of media-libs/gd before emerging geda

It's me that's broken, not the built_with_use check... ;o)

Thanks for reporting this bug, It's hopefully fixed now. I have made quite a
few changes to dependencies and use flag checks, so please do not hesitate to
reopen this bug if it didn't work.

*** Bug 173481 has been marked as a duplicate of this bug. ***

Reopen. Seriously, please test stuff before committing.

libgeda-20070216.ebuild:

<snip>
use gd && built_with_use media-libs/gd png || die "media-libs/gd must be
compiled with USE=png"
</snip>

Dies w/ USE="-gd"

geda-20070216.ebuild

<snip>
use gd && built_with_use sci-libs/libgeda gd || die "sci-libs/libgeda must be
compiled with USE=gd"
</snip>

Dies w/ USE="-gd" and *still* dies if media-libs/gd is not installed, plus the
use flag is just bogus.

Created an attachment (id=115550) [details]
geda-20070216.ebuild

Version that compiles fine with USE="-gd" and no gd installed.

Created an attachment (id=115554) [details]
libgeda-20070216.ebuild

same as above but for libgeda, tested working with gd flag off.

(From update of attachment 115550 [details])
Again - the use flag in the is bogus and doesn't do anything useful. Why is
this check needed in sci-electronics/geda anyway? Doesn't the one in libgeda do
the job already? 

Thanks Matteo, I'll look into this when I reach home.

Denis.

OK, it's fixed now. The story is that I thought I was smart enough to be able
to reduce the number of emerge to check all cases. Apparently I'm not.

Sorry for any annoyance.
Denis.

Don't get me wrong, but which part of

- the USE=gd is bogus in sci-electronics/geda

and

- it will *still* die if media-libs/gd is not installed

is so horribly unclear?

http://sources.gentoo.org/viewcvs.py/gentoo-x86/sci-electronics/geda/geda-20070216.ebuild?r1=1.3&r2=1.4

^^^ The above is still broken, drop the flag and drop the check.

To make it more clear, this
http://sources.gentoo.org/viewcvs.py/gentoo-x86/sci-electronics/geda/geda-20070216.ebuild?rev=1.1&view=markup
was last correct ebuild.

Either the check in sci-libs/libgeda is enough to make this compile no matter
what, or you have a missing dependency (hard one, not optional - because the gd
use flag doesn't affect sci-electronics/geda compile in any way).

On x86 seems emerging fine without gd, sorry...

#emerge -pv gd geda libgeda

Jakub,

Matteo, a couple other people I asked and myself can't reproduce your issue. So
I'm closing this bug. Feel free to reopen it with the usual necessary
information (detailed report, emerge info, etc...).

Denis.

OK, lets try again...

So, what you've done? You added USE=gd, which... uhm, does nothing. Doesn't
affect the compile result in any way. The only thing it does it checking
whether sci-libs/libgeda was compiled w/ USE=gd for whatever reason.

USE="gd" emerge libgeda geda -> nothing happens
USE="-gd" emerge  geda -> now it will die on the check, why?!

or

USE="-gd" emerge libgeda geda -> nothing happens
USE="gd" emerge  geda -> now it will again die on the check, why?!

The compile result is different whether libgeda is compiled with gd or not. As
a dev you should have seen that. The check is a workaround for Portage not
having USE flag dependencies yet. Since I don't work alone in my corner, I
contacted a senior dev about this, and he confirmed adding a gd USE flag was a
"sane" (his word) thing to do. Until I'm proved we were both wrong, this gd USE
flag is here to stay, sorry.

I would like to know why too. This problem couldn't be reproduced by 3 devs who
tried it on 4 different machines. I'm not saying your problem doesn't exist,
but as long as I don't have the necessary info to investigate I can't do much.

Eh. I give up. There's nothing to be seen in the ebuild, the flag doesn't do
anything there wrt the compile itself -> you apparently have an automagic
dependency here.

Wasn't that obvious ?

Anyway, I still believe it's important to know what happens in your case, and
why the checks die on your machine and not on others. If there's a real bug
waiting to be solved, we shouldn't stop here. So, please, send us the necessary
info.

Thanks in advance.

Denis.
