Description Thorsten Hirsch 2009-10-22 00:15:54 UTC

Version:            (using Devel)
Compiler:          gcc 3.4.3 SUNWgcc package
OS:                Solaris
Installed from:    Compiled sources

Linking fails due to "symbol referencing errors". I don't know why. The linker is:

$ ld --version

I've searched the whole web for this error. Most people get it, when some header file at compile time doesn't match the shared library at compile time. The header file is /usr/include/sys/socket.h and the corresponding shared lib is /lib/libsocket.so.1. The listed symbols in the error output are all available in the shared library, I checked it with nm. I have absolutely no idea what else could be wrong.

Comment 2 Thorsten Hirsch 2009-12-14 22:46:55 UTC

Okay, now I know why. The file...

kde/build/KDE/kdelibs/kinit/CMakeFiles/kdeinit4.dir/link.txt

...is missing the entry...

-lsocket

...so the linker doesn't link against the socket library and that's why these symbols are finally not being resolved.

So my question is: why is -lsocket missing? Who's responsible for creating link.txt? I guess it's cmake, but I had the same problem with cmake 2.6.x and now I habe it with cmake 2.8.0. Maybe there's also some entry missing in a kde build system file...? Or has it something to do with pkg-config?

Comment 3 Andreas Pakulat 2009-12-14 23:12:23 UTC

Can you test wether it helps to add ${KINIT_SOCKET_LIBRARY} in line 47 of kdelibs/kinit/CMakeLists.txt after the ${kdeinit_LIBS}?

Patch would be:

Yes, that's it! Thank you very much, Andreas!

Comment 5 Andreas Pakulat 2009-12-15 09:23:47 UTC

SVN commit 1062561 by apaku:

Fix linkage on systems where libsocket.so exists. kdeinit4 uses sockets, so
needs to link against the library.
