libkeduvocdocument on harmattan

Hi,

I'm trying to develop a very simple vocab-training application (lighter/less 
features than parley) for meego/harmattan. I already got this working somehow 
(I was able to compile and deploy it on my N9). Now I messed up my Qt SDK 
installation and had to reinstall it, but now I can't get my app to link 
against libkeduvocdocument. 
Can someone please tell me what I could have forgotten to install or setup?

I used the setupmad.sh script on 
http://community.kde.org/KDE_Mobile/Harmattan#Using_Madde to install 
libkeduvocdocument (and everything else that is needed) to the harmattan 
target.

The error that I get is
ld: cannot find -lkeduvocdocument

Thanks,
Roman

Scratchbox works fine, but as for MADDE: please make sure you have the
relevant package of the Community Repository installed in the MADDE
environment where the build procedure looks for.

I actually have installed all the relevant packages, mad-admin xdpkg -l gives 
me:
 kdelibs5-dev 
 libdbusmenu-qt2 
 libdlrestrictions1 
 libkdecore5 
 libkdeui5 
 libkeduvocdocument4 
 libkio5 
 libstreamanalyzer0 
 libstreams0 

Before, this also worked with MADDE, so there must be something else that I am 
missing. Any further ideas? 

Thanks and kind regards, 
Roman

Can you paste only the linker line, please ? We are looking for the
"-L" option here where the build procedure looks for. Use "make
VERBOSE=1" just for making sure. :) Also the content of the package
where that got installed ? In scratchbox, it is just simply "dpkg -L
libkeduvocdocument4", but I am unsure with MADDE.

Okay, this seems to be alright.

You do not have the symlink. I am not entirely sure for "ld", but try
to install libkdeedu-dev shipping that symlink or create the symlink
manually. That is the only gut instinct I can come up with.

Re: libkeduvocdocument on harmattan

Right, I think I am now having the full picture. You are using this
library for development purposes, not just linking. You definitely
need the development package for that. What I do not understand is
that, why you are not getting compilation issue, if you use the
library for development purposes. If you do not have the -dev package
installed, you would get compilation time issues as well.

Unless, you do not actually use the library, just link against, which
is not too useful. ;) I hope there are no stray header files around
why the compilation works, but the linking due to the missing -dev
package. That way, it would be necessary to clean up your system, but
hopefully this is not the case.

Re: libkeduvocdocument on harmattan

Ok, thank you so much, now it works again.

And you actually were right, I have a local git checkout of libkdeedu, I used 
these headers for compilation
(INCLUDEPATH += ../kde/libkdeedu/keduvocdocument /usr/include/KDE), which I 
probably did for testing stuff on my laptop.
I now changed this line to 

INCLUDEPATH += /usr/include/libkdeedu /usr/include/KDE

and I can now build again for my device.

Thanks again and best regards,
Roman

Can you paste only the linker line, please ? We are looking for the

Scratchbox works fine, but as for MADDE: please make sure you have the
relevant package of the Community Repository installed in the MADDE
environment where the build procedure looks for.
