Description Johannes Zarl-Zierl 2012-12-07 17:24:07 UTC

When building kipi-plugins against the stock libkdcraw version (2.0.1) in debian sid, libkdcraw is found successfully during the cmake step, but afterwards the build fails with the following error:
<pre>
CMakeFiles/kipiplugins.dir/widgets/kppreviewimage.o: In function `KIPIPlugins::KPPreviewImage::load(QString const&) const':
/home/zing/tmp/digikam-sc/extra/kipi-plugins/common/libkipiplugins/widgets/kppreviewimage.cpp:564: undefined reference to `KDcrawIface::KDcraw::loadRawPreview(QImage&, QString const&)'
CMakeFiles/kipiplugins.dir/tools/kprawthumbthread.o: In function `KIPIPlugins::KPRawThumbThread::run()':
/home/zing/tmp/digikam-sc/extra/kipi-plugins/common/libkipiplugins/tools/kprawthumbthread.cpp:112: undefined reference to `KDcrawIface::KDcraw::loadRawPreview(QImage&, QString const&)'
collect2: error: ld returned 1 exit status
make[2]: *** [lib/libkipiplugins.so.3.0.0] Error 1
make[1]: *** [common/libkipiplugins/CMakeFiles/kipiplugins.dir/all] Error 2
make: *** [all] Error 2
</pre>

I would expect that either the older version is rejected during the cmake phase and that kipi-plugins are built without libkdcraw support, or that kipi-plugins use KDcrawIface::KDcraw::loadDcrawPreview(...) when built against the older libkdcraw version.

It's a linking problem, not a compilation failure. Sound like you mix old and recent versions on your computer at the same time. 

Clean up your cmake cache, reconfigure and try again.

Comment 2 Johannes Zarl-Zierl 2012-12-17 20:38:34 UTC

You are right, the build-tree was improperly switched from manually installed libkdcraw to the system-installed one.

But even with a fresh build-tree, the issue hits me (during compilation, this time):

mkdir foo && cd foo && cmake .. && make

Comment 3 Johannes Zarl-Zierl 2012-12-17 21:04:48 UTC

Created attachment 75892 [details]
[PATCH] Refuse to build when libkdcraw version is too old.

I looked at the output of cmake again and noticed that there is a version check for libkdcraw, but it has no effect on the compilation.

I guess that KDCRAW_FOUND should be set to false, if no version info is found.
