[gentoo-user] tif libraries being ignored

[gentoo-user] tif libraries being ignored

[Ted Miller]

I am new to Gentoo (not new to Linux), and am trying to do a Gentoo 
install to handle my photo needs.  I have emerged cinepaint, gimp, 
hugin, KPhotoAlbum, Krita and ufraw (for starters).

Things work pretty well EXCEPT that the KDE based applications cannot 
handle *.tif files.  I have the media-libs/tiff package emerged, but for 
some reason the KDE subsystem does not seem to be using it.

What doesn't even list .tif files as graphics files:
KView

What doesn't work with .tif files:
krita preview in File>Open dialog
KPhotoAlbum does not show .tif files
gimp lists the files, but puts up an error message when it attempts to 
open the file
KView

What does work with .tif files:
Krita will open them (just not preview them)
hugin
cinepaint (not KDE based)


If I tell konqueror to open a .tif file with KView, the KView status bar 
says "Unknown image format: /"...."/A00001658.1.tif"

If I tell konqueror to open a .tif file with GIMP, I get two GIMP Messages:
PDB calling error: Procedure 'file-tiff-load' not found.
Opening '/.../A00001658.1.tif' failed: raw image plug-in could not open 
image

I have run
emerge --update --deep --newuse world
revdep-rebuild
with no improvement

Any insight into what I need to do to get this working will be greatly 
appreciated.  Please be explicit (or include links to documentation) if 
I have to do anything unusual, but I will be glad to send any needed 
information to help you diagnose my problem.

I would assume you have tiff in your USE line in make.conf? 

root@smoker / # euse -i tiff
global use flags (searching: tiff)
************************************************************
[+ CD ] tiff - Adds support for the TIFF image format

local use flags (searching: tiff)
************************************************************
[+ CD ] tiff (media-tv/mythtv):
Add support for tiff loading and rendering which is only used by
media-plugins/mythgallery

root@smoker / #

Just in case you missed that little detail.  ;-)

Yes, I missed that, and it did the trick (after re-emerging 11 packages, 
including kde-libs).

Where was it hidden, that I missed it?  Or is it just one of those things 
"you have to learn"?  Seems like the tif package should add it, or tell me 
to consider adding it, when the package is installed.

Since you are new to Gentoo, use the -v and either -a or -p first.  It
will show you what USE flags it will build with because of the -v.  If
you are not sure what they are, just do a euse -i <flag_name> and see
what it says.  Some make sense but some don't.

I'm sure it is documented somewhere but I have just learned the steps in
doing things over the years.  Most of them the hard way but learned them
still.

Glad you got it working tho.  It was all I could think of that would
keep it from it.

What command do I use those with -- emerge, euse?  So far I learned about 
flags with equery.

That would be emerge.  Sorry.  Should have been more clear on that. 
Should look something like this:

root@smoker / # emerge -pv gimp

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

Calculating dependencies... done!
[ebuild   R   ] media-gfx/gimp-2.4.6  USE="alsa curl dbus exif hal mmx
pdf png python sse svg tiff wmf -aalib (-altivec) -debug -doc -gnome
-gtkhtml -lcms -mng -smp" 0 kB

Total: 1 package (1 reinstall), Size of downloads: 0 kB
root@smoker / # 

You may want to consider using a profile that is most closely to what
you are doing.  I think eselect is what most folks use to set theirs.  I
do mine manually but may as well learn the right way while you are
learning.  There are a few of them but desktop may be the one you want. 
It has a lot of USE flags already enabled.

Have a look at the documentation about USE flags. It's part of the Gentoo 
Handbook, in the section about working with Gentoo:
http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=2&chap=2

Because you had the tiff flag turned off, Gentoo assumed you didn't want all 
those packages on your system to be linked against the tiff libraries (for 
whatever various reason). Therefore even though you installed the libraries, 
the packages themselves hadn't linked against them.

You might want to check your use flags for other media related flags, 
depending on which file formats you'll be using (off the top of my head there 
are a couple of flags for various picture formats).

And welcome to Gentoo! :)

I found that, and think I understand how it works, having had to put in 
several flags to get things working already.  However, most of what I have 
done so far has been in response to messages like (roughly): "Sorry, I 
can't compile Package A unless Package B is compiled with the XYZ flag. 
Please set flag, recompile B, then recompile A."

As a new user, what I need to know is: How do I find out that there is such 
a thing as a 'tiff' flag?  I could just as easily have checked for a 'tif' 
flag, and not known that it was 'tiff'.  Nothing told me that installing 
the library didn't do anything until I set the related flag.  Seems like 
either:
1. The library should set the flag itself (which not everyone wants to 
happen, as they may only want it for one package, not all) or
2. There should be a message after the emerge, kind of like the one that 
says (roughly) "You have 3 configuration files in /etc which need attention" or
3. There should be a list somewhere that is automatically maintained that 
says something like: "You have installed packages related to these flags. 
To get full benefit from these packages, consider adding these flags to 
either make.conf or to the make instructions for individual packages", and 
then list all the flags, maybe one package to a line, with that package's 
flags listed on the line after that package name, kind of like
qt-3: qt3
qt-4: qt4

Currently my make.conf contains: USE="-gtk -gnome qt3 qt4 kde dvd alsa cdr hal
exif -ipv6 X samba openexr tiff", but I wonder what else is missing, and 
how do
I find out?

I just ran 'equery uses gimp' and find flags like dbus lcms mmx mng pdf png 
sse svg and wmf that MAYBE I should set.  And how do I figure out which are 
gimp-only and which are widely used flags, and exactly what they do, 
without running 'equery hasuse dbus' for each flag on that list?

slightly confused,
Ted Miller

There are use flag editors which will display entire list of flags
(along with their descriptions) and let you select or deselect the ones
you want. I use ufed, but there are some others in portage.  One
approach is to go through the list once (there are a lot of them) and at
least select the ones you're sure you want.  Then if ever some feature
you wanted doesn't seem to be in place for a package, check its use
flags.
