Michal, This warning is given because the development package is not installed (witch include header file to compile) Gilles Caulier 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?). Arnd 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... Gilles Caulier Created attachment 21036 [details] 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. Thanks, I think this should solve the problem for most people. OK, I will ask that the patch gets applied (therefore re-opening until then). Gilles, may I apply the patch (#6) and close this bug then? Arnd, Yes of course.

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.
