Arch Linux

When i start kdevelop i get a Could not create language plugin for C.

This is in kdevelop's FAQ

I get an error message "couldn't create a language plugin". What is wrong?

Just as any other KDE application, you have to make sure that KDevelop's plugins are recognized by KDE. Either install it into your KDE directory (configure --prefix=/opt/kde3 for example) or add KDevelop path to your KDEDIRS environment variable and rerun "kbuildsycoca". Example command line for bash (assuming KDevelop is installed in /home/harry/kdevelop):

export KDEDIRS=/home/harry/kdevelop:$KDEDIRS && kbuildsycoca


If the error is specifically "Could not create language plugin for C++.", try also making sure you have a valid bdb (Berkeley DB) installation.

You should see something like this:

ldd ~/devel/install/lib/libkdevcatalog.so | grep libdb
libdb-4.3.so => /usr/lib64/libdb-4.3.so (0x00002ba8687c9000)

If you see something like this:

ldd ~/devel/install/lib/libkdevcatalog.so | grep libdb
libdb-4.3.so => not found

then your distro's package management hasn't managed to track the bdb dependency correctly and you need to install a compatible bdb version.


when i do.. ldd /opt/kde/lib/libkdevelopcatalog.so|greo libdb
i get... libdb-4.4.so => not found
