Hi All

I have an old KDE3.3 installed on my machine. Now I want to install a new KDE3.5(Not upgrade the old one) to use its KPDF 0.5. I was able to build the new KDE successfully and installed it under /opt/kde.

My problem is when I execute /opt/kde/bin/kpdf (0.5), it will automatically look for /usr/lib/kde3/libkpdfpart.la (provided by KDE3.3) rather than /opt/kde/lib/kde3/libkpdfpart.la. The consequence is that the ui of KPDF0.5 is in old KPDF 0.3 style.

My workaournd is to copy libkpdfpart.so and libkpdfpart.la into /.kde/lib/kde3. But it is not wise since if anyone wants to use it, he/she has to do this redundant job.

Is any way to solve this? Or did I miss any parameter in terms of building KDE3.5?

You probably need to add the following global environment variable if not already present:

Code: Select all

export LD_LIBRARY_PATH=/path/to/kde/3.5/install:$LD_LIBRARY_PATH

HI Bcooksly

Actually, I have tried "export LD_LIBRARY_PATH=/opt/kde/lib/kde3", but it does not look. From the strace output, my kpdf still prefers the default location to open libkpdfpart.la.

I think this is because /usr/lib/kde3 is prior than /opt/kde/lib/kde3 in certain library list.

Can you post the output of "ldd kpdf" both before and after setting LD_LIBRARY_PATH?
LD_LIBRARY_PATH should be set to $KDEDIR/lib ( where KDEDIR is /opt/kde for you )
Also, if you haven't set $PATH to include $KDEDIR/bin/ please do.

Code: Select all

export PATH=$KDEDIR/bin/:$PATH
export LD_LIBRARY_PATH=$KDEDIR/lib/:$LD_LIBRARY_PATH

Hi bcooksly

Here is the output. You see the output does not change before/after setting LD_LIBRARY_PATH and does not contains libkpdfpart.so.

After reading the code, I found libkpdfpart.so should be loaded through code as following.

Code: Select all

 KParts::Factory *factory = (KParts::Factory *) KLibLoader::self()->factory("libkpdfpart");

I will dig deeper into KLibLoader class to figure out how its load order works and update this thread.

Code: Select all

Have you set the environment variable $KDEDIR to point to /opt/kde/?

Hi bcooksley

It works after setting $KDEDIR according to your advice.
Thank you for the support.
