[RBendo]

Hi, i don't know english very well, sorry
I've a problem with a small program by me writed, It's a template class, after the compile time, in linking time
Codeblocks tell me:

s - source\PROGETTI\GCL\GCL_TESTER.CPP  | 14   |    undefined reference to `GCL::IOFile<GCL::Void0, GCL::Void1,
                                                                     |    GCL::Void2, GCL::Void3>::IOFile()'

obj\Debug\GCL_TESTER.o   |    In function `_ZN3GCL6IOFileINS_5Void0ENS_5Void1ENS_5Void2ENS_5Void3EElsEh':
(unsigned char)]+0x3b)      |    undefined reference to `GCL::IOFile<GCL::Void0, GCL::Void1, GCL::Void2, 
                                     |   GCL::Void3>::Write  (unsigned char, unsigned short, char*)'|

I don't know how to solve this problem, anybody can help me? ( Sorry for english too ).
