First KFilePlugin problem

Hi All,
I'm trying to create my first KFilePlugin with the help of:
- KDevelop Project Wizard
- Providing file meta-data support with KFile plugins

But when I test the Plugin Konqueror send me the following error:

KFileMetaInfo: WARNING: error loading the plugin from kfile_mng.desktop


I'll post my kfile_mng.desktop that for me seems correct.

[Desktop Entry]
Encoding=UTF-8
Type=Service
Name=MNG Info
ServiceTypes=KFilePlugin
X-KDE-Library=kfile_mng
MimeType=text/html

I have changed the mimeType even in kfile_mng.cpp

Please help :-(

P.S.: The information that I want to display are only Size and Items

text/html?

The name of the plugin would suggest it works on mng files, not on HTML files.
In case it does work on mng files, have you tried the respective MIME type?

I haven't tryed the respective MIME typese for two reason:
1 - The information that this KFilePlugin add is just the size of the file
2 - I have changed the souce code so it should be usable for text/html file

You could check if the debug areas for KMetaFile and its plugins are activated (using kdebugdialog) and then run Konqueror from a Konsole to see the debug output.

Maybe it has some hint on what it failes to get from the plugin.

Konqueror give me these messagese when I righe click on some file that should be handled by my plug-in:
KFileMetaInfo: WARNING: error loading the plugin from kfile_mng.desktop

I have tryed to use kdebugdialog but I don't understand what should I look for.

Also looking to the diffences to my project and the one in the tutorial I have found that:
- I compile only my plug-in and not the whole KDE enviroment
- I put kfile_mng.desktop, kfile_mng.la, kfile_mng.so in the same directory that is /home/<user>/.kde/share/services/

It allows to enable specific debug output categories, for example from kdelibs library loader, etc

Well, that is correct for the .desktop file, but the library has to be one of those:
kde-config --path module

Usually when developing something plugin like one installs into a special prefix, in order to create the same situation as later in a real install.

The additional KDE directory can be added to the KDEDIRS variable, so there is no need to install into the package manager controlled tree.

Thank you for your good hint.

But now I trying to change strategy, I've open a new project from KDevelop using the wizard for KDE/KFilePlugin and without changin any line of code I have compiled and installed the project.

KDevlop have created an automake project so that when I've launched:
make install
I have seen

Source code

test -z "/usr/local/kde/lib/kde3" || mkdir -p -- "/usr/local/kde/lib/kde3"
 /bin/sh ../libtool --silent --mode=install /usr/bin/install -c -p  'kfile_kfiletest.la' '/usr/local/kde/lib/kde3/kfile_kfiletest.la'
PATH="$PATH:/sbin" ldconfig -n /usr/local/kde/lib/kde3
test -z "/usr/local/kde/share/services" || mkdir -p -- "/usr/local/kde/share/services"
 /usr/bin/install -c -p -m 644 '/home/kismet/Progetti/kfiletest/src/kfile_kfiletest.desktop' '/usr/local/kde/share/services/kfile_kfiletest.desktop'


That I think that update the library of KDE.

Now when I right click on html file I don't get the error message from Konqueror, but I'm unable to see the extra Tab create by me :(

Check that KDEDIRS includes your default KDE directory and /usr/local/kde

For example
#> env ¦ grep KDEDIRS

should at least look like this
KDEDIRS=/usr/:/usr/local/kde

(assuming your KDE is installed in /usr, if in doubt run kde-config --prefix)

This has to be present at the time startkde runs.
If it isn't yet you easily expand the startup environment by putting a small shell script in and of the directories listed by the following command

#> kde-config --path exe | sed s#bin#env#g

The shell script would then include something like this
---- kdedirs.sh -----
export KDEDIRS=/usr:/usr/local/kde
