Legacy Code Tool / Linker Error LNK2019 and LNK1120

Hi,

i'm trying to import existing c-code into simulink via using Legacy Code Tool (LCT) and getting two linker errors (see topic) which i am not able to understand.

The LCT configuration is as followed:

def=legacy_code('initialize');
def.HeaderFiles={'nap_control.h','nap_control_alg.h','types.h'};
def.SourceFiles={'nap_control.c','nap_control_alg.c'};
def.SFunctionName ='nap_control_LCT';
def.OutputFcnSpec ='napControl_GetCosPhi (single y1[1], uint8 u1, uint8 u2, single u3, single u4, boolean u5, single u6, boolean u7)';
legacy_code('sfcn_cmex_generate',def);
legacy_code('compile', def);
legacy_code('slblock_generate', def);

After typing the LCT-command "legacy_code('compile', def);" i get following error message:

### Start Compiling nap_control_LCT

MATLAB-Version: 2011b
Compiler: MS SDK 7.1 (MS C++ 2010 Express was delivering the same error message)
System: Windows 7 64bit

Have anyone an idea? Would be nice if someone have some time and could give me some advice,
