This just means SWIG won't generate a wrapper to modify 
pseudogroup_type_namelist and is unrelated to your linker problem.

Probably this is due to the SWIG generated wrapper to read/get 
pseudogroup_type_namelist. If you compile your code with 
DEFINE_PSEUDOGROUP_TYPE_NAMELIST defined, the symbol will no longer be 
extern and the symbol will be defined, hence the linker will find the 
symbol.

You need to look in your code and see what is calling these methods and 
find out where they are defined and link to the dll that defines them.

These linker problems don't look typemap related to me.
