These symbols are defined in libdl.[a|.so], which is a part of
libc6-dev. You'll need to install that library (maybe it has a
slighly different name in Slackware).

You have a problem when linking to libccpunit.
Try to locate libcppunit.so on your computer.
In my case this library is located in /usr/lib and not in /usr/local/lib.
When building the library you should change the option CPPUNIT_INSTALL (I
think yours is set to /usr/local in stead of /usr).

Let me know if you make any progress!

I also got this error while building KDL. My platform is CentOS 5.2, CPPUNIT-1.12.1, KDL-svn. I googled a bit and realize that it requires "-ldl" at linking stage.

I then add "-ldl" to "CMAKE_EXE_LINKER_FLAGS" and solved this error. It's with "cd build; ccmake ..; [t] toggle to advance mode; edit CMAKE_EXE_LINKER_FLAGS as -ldl".

Hopefully, this would help for the other people who also hit this error.

I didn't really solve the problem, you just worked around it.
As a consequence you will not be able to run the cpp-unit tests, but all your
programs will probably run fine.
If you would ever try to get the CPPunit tests to work, I'm interested in the
solution. (PS: also check the solution proposed by Klaas Gadeyne on the
mailinglist).

Doesn't slackware offer libc packages?
