ld problem

["tcheer at gmx dot de" <tcheer at gmx dot de>]

Hi  folks,

I have written an application, compiled and created a library(I called 
it libmustik.so) , using gnu g++-2.95.3.
Later on I wrote some test cases, using CppUnit, using my newly created 
library.
I encounted the problem that ld failed during linkage, throwing me some 
undefine references on some methods in my lib.

g++ -O0 -Wall -fpic -pthread   -I../../inc -o MustikTest MustikTest.cpp 
-L../../lib -lmustiktest -lmustik -lpthread -lrt -lcppunit
../../lib/libmustik.so: undefined reference to 
`fs::Collection<fs::FileSystem>::~Collection(void)'
../../lib/libmustik.so: undefined reference to 
`fs::_Iterator<fs::FileSystem>::~_Iterator(void)'
../../lib/libmustik.so: undefined reference to 
`fs::_Iterator<fs::FileSystem>::_Iterator(void)'
../../lib/libmustik.so: undefined reference to 
`fs::Collection<fs::FileSystem>::Collection(void)'
../../lib/libmustik.so: undefined reference to 
`fs::Collection<fs::FileSystem>::getPatternSet(void)'
collect2: ld returned 1 exit status

That brought me to think I had a problem in my code. I looked for it 
whithout success ( as far as my c++ knowledge allows it ), all mentioned 
methods have been properly implemented, I think.
Running the same compilation with the 3.2 version throwed me even more 
error messages than whith the 2.95.3 version, there were a lot of 
CppUnit methods that could not be referenced, what brought me to think 
the problem may not lay on my code but on a wrong usage of g++...

...

undefined reference to `streambuf::pbackfail(int)'
../../lib/libmustik.so: undefined reference to 
`fs::_Iterator<fs::FileSystem>::_Iterator[not-in-charge]()'

/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.2/../../../libcppunit.so: 
undefined reference to `streambuf::xsputn(char const *, int)'
...

I would appreciate some help solving this problem.

Thanks
