           Summary: Can't link against static libjasper, configure reports
                    jasper is missing
           Product: digikam
           Version: unspecified
          Platform: Slackware Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: setup
        AssignedTo: digikam-devel kde org
        ReportedBy: mkosmul users sourceforge net


Version:            (using KDE KDE 3.5.7)
Installed from:    Slackware Packages
Compiler:          gcc 4.1.2
OS:                Linux

While compiling Digikam 0.9.2, if jasper (1.900.1 or 1.701.0) was compiled without --enable-dynamic (only static libraries are available), digikam's configure complains about libjasper not being installed ("WARNING: digiKam requires libjasper >= 1.7.0") and aborts.

Michal,

This warning is given because the development package is not installed (witch include header file to compile)

What do you suggest?
Should the warning be changed to
"WARNING: digiKam requires libjasper >= 1.7.0 (shared library version,
--enable-dynamic during configure of libjasper)"

Or should digiKam also accept a static library?
(Not sure if this would be a good option, personally I think
that libjasper should generate a shared library version
per default ...)

Note that this is also mentioned under:
  http://www.digikam.org/?q=download/dependencies
which it is linked from
  http://www.digikam.org/?q=download

Best, Arnd

Gilles, are you sure?

By default, installing libjasper only creates static libraries,
which are not recognized by digikam
(or has this changed?).

Yes, both in jasper 1.900.1 and 1.701.0 the default is static libraries only. It took me a while to find out what was wrong since on Slackware I had to compile this library from source (no packages for it in the distro) and I expected that the default options would work.

Michal,

All linux distributions separate now binary and devel packages to optimize space used on host computer.

Binary package include shared library component witch is used to link with host program. It cannot be used alone to compile a program witch will use the library. This package is used to run a program already compiled witch use the library.

Development package is used to _compile_ the host program ! This is completly different. When you install bin package, generally devel package is not installed. The automake/autonconf script from digiKam test if devel package is installed, not the bin package.

Look README file to check all depencies...

Created an attachment (id=21036)
 --> (http://bugs.kde.org/attachment.cgi?id=21036&action=view)
more precise warning

The attached patch gives a more detailed explanation.
Full text in case of error after applying this patch:
 
 digiKam needs libjasper to support JPEG2000.
  You need to install the correct version (>= 1.7.0).
  Libjasper website is at http://www.ece.uvic.ca/~mdadams/jasper
  Important note: libjaspeer has to be configured with --enable-dynamic
  as otherwise the required dynamic libraries are not created.



Personally I think that this should be enough. There
is no need for digikam to work around configure choice of 3rd party software.

OK, I will ask that the patch gets applied (therefore re-opening until then).
