Configure script cannot find exiv2. I have exiv2 0.12 but pkg-config cannot verify that and refuses to compile digikam and digikamimageplugins.

Mikolaj,

Are you installed properlly Exiv2 library ? Here, i'm use "./configure --prefix=/usr" under Mandriva...

Angelo,

What's wrong in .configure.in about Exiv2 version check ?

Yes. I installed properly and as usual programs compiled from sources
are going to /usr/local

Looks like pkg-config has problems with that. Since exiv2-config
supports libs/flags options maybe you should scratch pkg-config and use
exiv2-config instead?

About comment#2 error exiv2 >= 12 ... no. (12?) strange.
Anyway it works here (mandriva 2007), did you try to download the
srpm from cooker and backporting it? as soon as possible i'll try to provide
a backport package for mandriva.
Anyway to comment#4 I should say it's not on a conventional directory,
mandriva installs all into /usr -i strongly recomend to use srpm anyway-
so you should use PKG_CONFIG_PATH in order to provide /usr/local/lib/pkgconfig
to compile, in the same way I believe you do with LD_LIBRARY_PATH to provide /usr/local/lib first for share libraries to run your applications.

Mikolaj,

Also, if you can compile kipi-plugins, why you cannot do it with digiKam ?

kipi-plugins Exiv2 check from .configure.in is the same on both...

I've had an "old" kipi-plugins. Didn't want to recompile them, just went
straight to Digikam.

To comment #4: Please use pkg-config with exiv2.pc, not exiv2-config. exiv2-config has been marked as deprecated since (I think) 0.10, I don't plan to ship it with the next version anymore.

If there is something wrong with exiv2.pc, report it as a bug.

(Maybe its the same "bug" that Daniel already triggered)

Do you have a second version of exiv2 installed? If yes, where are the two exiv2.pc installed?

Bye

Andreas, with that I believe i won't go back on my steps, but,
there's always a but, I found this problem using  pkg-config alone:
#exiv2-config --libs
-L/usr/lib -lexiv2 -lz -lm
while
#pkg-config exiv2 --libs
-lexiv2

#pkg-config exiv2 --modversion
0.12

Regards,
        Angelo

That's ok. -lz and -lm are only needed when linking statically:

ahuggel mowgli> pkg-config --libs exiv2
-L/usr/local/lib -lexiv2

ahuggel mowgli> pkg-config --libs --static exiv2
-L/usr/local/lib -lexiv2 -lz -lm

[anaselli proj9 src]$ pkg-config --libs exiv2
-lexiv2

there's no -L/usr/lib but maybe that's ok because it's standard...

Angelo,

Look like Andreas recommend to use pkg-config with exiv2.pc, not exiv2-config.
See comments #9...

It's the case actually in .configure script ?

almost, it's a hybrid yet, we use  pkg-config to get the module isntalled and
exiv2-config to get [c|ld]flags. I'll change it asap

I just tag this file like VHI because it must be fixed before digiKam 0.9.0-final release planed at Christmast...

Gilles, I can't see the problem, the reporter doesn't want pkg-config
while Andreas said it's a must. I cannot fix it in the way the reporter wants,
I can only use pkg-config alone instead of a mix. Tell me what to do,
but as far as i can say this bug is invalid, but if the reporter shows
that PKG_CONFIG_PATH doesn't work.

P.S. BTW I'm not a digikam developer :p

Sure (:=))), but .configure Exiv2 detection is common on kipi-plugins and digiKam (the same in fact). If something must be fixed into digiKam, the same thing must be done in kipi-plugins.

As exiv2-config is marked as deprecated by Andreas, I would suggest to only use pkg-config. IMHO, pkg-config is ok, if there are troubles, it could be because of some scripts using it, but not pkg-config itself...

And, this will also solve the problem I mentionned in my email here :
http://mail.kde.org/pipermail/digikam-users/2006-December/002628.html

<<
But, in any case, it's true that there's something confusing in the
configure script :
- first, EXIV2_CFLAGS and LIB_EXIV2 are defined :

EXIV2_CFLAGS="`$EXIV2_CONFIG --cflags`"
LIB_EXIV2="`$EXIV2_CONFIG --libs`"

- then, EXIV2_CFLAGS is redefined and a new EXIV2_LIBS is defined (and
not LIB_EXIV2) :

EXIV2_CFLAGS=`$PKG_CONFIG --cflags "exiv2 >= 0.12"`
EXIV2_LIBS=`$PKG_CONFIG --libs "exiv2 >= 0.12"`

I don't know yet which one is the right one, but I guess we shouldn't
have both LIB_EXIV2 and EXIV2_LIBS at the same time...
