Using library problem on KDevelop

Hi all,
I'm a beginner in KDevelop. I want to write some tools by Kdevelop/Qt.
And I stuck in trouble now. I can not use any libraries (Ex: kmdi, open gl,...). Every time I use them (put them in link option of project), Kdevelop is hang when linking (can not link). So I wonder:
- What's wrong with this ?
- How to check if those libraries are installed in my PC ?
Pls help me to solve it.
Thanks

RE: Using library problem on KDevelop

Use the (very) old unix command locate:
locate kmdi
will tell you where the thing is.

For more information about locate use the man page: man locate

RE: Using library problem on KDevelop

Hi all,
I checked as you suggested and found that the libraries I intent to use are installed. So, I wonder why KDevelop can not link them ? and what should I do next ?
If any of you have free time, pls show me step by step when you want to use a library in KDevelop.
Help me, pls...

How does the linker output look like?
(Try running make in a console window inside the project directory)

Link libraries problem

Hi anda_skoa,
I tried to run make command as your suggestion and the error is "/usr/bin/ld: cannot find -lselinux". And I found that there is a libselinux.so.1 file in folder /lib.

What do you need libselinux for?

If you really need it, you might be missing the devel package for it, which usually creates a link from libname.so to libname.so.version
You can do that manually:
cd /lib
ln -s libselinux.so.1 libselinux.so
