Bugzilla Bug 133376

I'm having trouble compiling app-text/gocr that is required with updating
media-video/dvdrip package (I didn't have it installed before, it's probably
new dependency with USE flag subtitles set). I try to emerge with command
emerge -a -u -D -v --newuse world. Output looks as follows:

[ebuild  N    ] app-text/gocr-0.39  -doc +gtk 0 kB 
[ebuild  N    ] media-video/subtitleripper-0.3.4-r1  +png +zlib 46 kB 
[ebuild     U ] media-video/dvdrip-0.52.7-r1 [0.52.0] +cdr -gnome -minimal
-mplayer +ogg -rar +subtitles* +xvid 513 kB

And when I continue with emerging, I come across the following error:

Which version of media-libs/netpbm do you have?

As far as I can see this is fixed in gocr-0.40.
Could you please try that version and report back here.
If it works we will try to mark gocr-0.40 stable.

Both 0.40 and 0.40-r1 compiled perfectly, thank you. But I would rather avoid
using software marked as unstable if possible, so I will appreciate if 0.40
will get marked stable ;-).

Arch teams: Please mark app-text/gocr-0.40-r1 stable. It fixes a bug in 0.39
and includes a --as-needed patch. There are no other bugs open for gocr. I know
0.40-r1 has not been in the tree for a month, but 0.40 has and it is the same
except for the --as-needed patch.

The gtk frontend doesn't work fully here (amd64):

when i add a file to the list, select it and click 'view' nothing happens,
except the output in the shell:

sh: display: command not found

seems like you're missing a dependency

That would be imagemagick. Can you please install it and tell us if it solves
your problem?

(In reply to comment #9)
> That would be imagemagick. Can you please install it and tell us if it solves

It does.
I have never tried the gtk interface (my bad) only the commandline interface.
Upstream is not very good at describing deps for gocr... I can't find a single
location where the dep on imagemagick is mentioned.
Nattfodd: Feel free to add the dep on imagemagic (but only if the gtk use flag
is enabled), otherwise I'll do it when I get to my gentoo box tonight (CEST).

I added gocr-0.40-r2 with this new dep (and removed INSTALL from dodoc btw).

Dear arch teams which didn't stable 0.40-r1 yet, please do it on 0.40-r2
instead (if you are ok with it, of course).

@ppc64: if you stable -r2, I'll be able to remove -r1.

thanks! -r2 stable on ppc64.

Thanks, 0.40-r1 has been removed.

Unkeyworded,

[ebuild   R   ] app-text/gocr-0.40-r2  -doc +gtk 0 kB

and built it with collision-protect on x86 and it seems to be fine.

Thanks, drac

x86 done

Seems to work, tested with some examples on their homepage.  Marked ppc stable.

removing ppc from cc

SPARC stable.

works as far as i would expect it from an OCR app ;)
