I looked for similar problems, but the only topic might be the one on the use of a library, which I would avoid... here is my issue, I get this error:

```
1>Signal generator.obj : error LNK2001: unresolved external symbol "double __cdecl findMaxModulus(double *,int)" (?findMaxModulus@@YANPANH@Z)

```

I am using visual studio professional 2008 to develop a c program. I have a main file and another file with all the functions I wrote, myFunctions.h/c. The problem is that these errors do not come out when I include "myFunctions.c", while they come out when I include "myFunctions.h".

i am doing what i remember from university (i am much more into matlab now), which is

```
/* Home-made includes */
#include "myType.h"
#include "myFunctions.h"

```

just after the inclusion of the othe headers (stdlib, math, etc...)

any guess? thank you
