I've got an app which won't link, giving error:

/usr/lib64/libcroco-0.6.so.3: undefined reference to `xmlGetProp@LIBXML2_2.4.30'
/usr/lib64/libcroco-0.6.so.3: undefined reference to `xmlFree@LIBXML2_2.4.30'
/usr/lib64/libcroco-0.6.so.3: undefined reference to `xmlHasProp@LIBXML2_2.4.30'

I've got libxml installed:

libxml++.x86_64                  2.33.2-1.fc15      @koji-override-    0/$releasever
libxml++-devel.x86_64            2.33.2-1.fc15      @fedora                     
libxml2.i686                     2.7.8-6.fc15       @fedora                     
libxml2.x86_64                   2.7.8-6.fc15       @koji-override-0/$releasever
libxml2-devel.x86_64             2.7.8-6.fc15       @fedora                     
libxml2-python.x86_64            2.7.8-6.fc15       @koji-override-0/$releasever

Any ideas? Maybe libcroco was compiled with older version and I need older libxml installed?

  • Show us the linker command line, and the output of ldd /usr/lib64/libcroco-0.6.so.3. Jul 22, 2011 at 13:16
  • thanks, libcroco was looking for libxml in a strange place :) works now...

  • I'm getting the same issue. Which strange place was it? How did you fix it?

The only thing I can think of is that the .so files aren't in a directory the linker looks for libraries in. Can you find out where the file libxml2.so resides, and then put that directory on the link command line with a -L ?

  • yeah, for some reason, libcroco was looking for the file in the absolutely wrong place :)

Although is a versioned symbol it still seems to be the current, linkable, version of the symbol in 2.7.8 as far as I can see.

I take it you do have -lxml2 on your link line? If you're relying on linking to libcroco pulling it in then that won't work on recent Fedora releases and you will need to link against it directly.

  • yes, i've got -lxml2...
