new requirement libjpeg.la?

Hello,

I have problems to compile current SVN version of digikam. I have already
recompiled libkexiv2, libkipi, kipiplugins, etc.
But digikam fails because of a missing libjpeg.la file:

/bin/sh ../../../../libtool --silent --tag=CXX --mode=link

Slackware 11.0 includes the package libjpeg-6b-i386-4 but it does not contain
any libjpeg.la file. Is this file required now, because I had no problems
compiling older versions of digikam.

Thank you very much for any comments.

Regards,
Klaus

apt-file search libjpeg.la
libjpeg62-dev: usr/lib/libjpeg.la

Yes, I thought it should be in this package. But it is not included in the
Slackware libjpeg package. Slackware does not know such -devel packages.
Everything is included in just one package, so I cannot have forgotten to
install a devel package like in other distros.

I have complied digikam many times before, but it never failed because of this
file. So I was just wondering.

Klaus

Well, # ldd /usr/bin/digikam|grep libjpeg
        libjpeg.so.62 => /usr/lib/libjpeg.so.62

So I guess the .la file is needed for compilation. I don't know for sure, but
it would surprise me if this was a new dependency, it's such an essential
library.

Hello,

sorry for the late reply, but I tested bit around the last day. I can compile
digikam 0.9, but not 0.9.1-beta1. It breaks with the error I posted before
about missing libjpeg.la

The installed digikam 0.9 links to libjpeg.so.62, without existing libjpeg.la
on my Slackware system.
ldd /opt/kde/bin/digikam | grep libjpeg
        libjpeg.so.62 => /usr/lib/libjpeg.so.62 (0xb6616000)

So it seems there has changed something how digikam compiles?
Thank you very much.

Well if the library exists on your system (locate -e libjpeg.so.62), which
seems to be the case, the only error (I can imagine) possible is then the
paths variables that don't find it. Can you check the Makefile and
Makefile.in of the relevant sub-directory?

Hello,

Thank you very much for all your help. I found the problem finally. I had to
install libjasper as a new requirement to compile digikam. And the file
libjasper.la from libjasper included a new dependency to libjpeg.la. :( I
removed that dependency in /usr/lib/libjapser.la and it seems that digikam
compiles fine now.

Hi everybody,

Just a question about libjasper requirement : Digikam could work
without if you don't want to use JPEG-2000. Many applications handle
that at configure time, and do not compile that part if that optionnal
part is not there. I don't know if it's difficult to handle as I don't
know at lot about autoconf/automake stuff but is it possible for
digikam ?

Perhaps it's to late now as I think I've read somewhere that, with
KDE4, autoconf/automake will not be used. Perhaps it's somethink to
think about during the migration.
Being able to reduce the dependancies, at least at configure/compile
time is a good thing.
Even better (but it's probably not possible with actual tools) would
be to handle these requirements at run time, but I'm dreaming.

Regards,
  Loïc

P.S.:keep on doing this nice work.
