[PythonCE] compiling for winCE

[Ajay]

hi!

i tried using SWIG and both my .ccp and wrap.cpp compiled fine. however
when i try to link them i get an error

Linking...
   Creating library ARMRel/mytest1.lib and object ARMRel/mytest1.exp
mytest_wrap.obj : error LNK2019: unresolved external symbol "int __cdecl
incrementNumber(int)" (?incrementNumber@@YAHH at Z) referenced in function
_wrap_incrementNumber
ARMRel/mytest1.dll : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

mytest1.dll - 2 error(s), 0 warning(s)

i have no idea where the error is coming from

help would be much appreciated

cheers
