Is any information missing for linking here? commands aren't available. (Undefined command: "py-bt". You've specified that your libchild.so depends on libparent.so.

Now, Boost 1.48p1 is built on the python we built with UCS4 support, so there are no UCS2 missing references. Many thanks in advance! You do this when you are creating the child library: g++ -shared -o libchild.so child_file1.o child_file2.o -Lparent_directory -lparent Note that order is important.

Type "show copying" and "show warranty" for details. Also, Boost 1.48p1 contains the THREADS patch for gcc4.7, which we solved after the gccmax move to 4.7 I hope it's more or less clear with all this mess.
