Aihe: Re: [DNG] Pointer error in the backend of Netman
Hi Edward,

Now i get the following error trying to compile the backend:

" ... automated_scanner.c:291: undefined reference to `pow' ... "

The 'pow' function is part of the 'math' library. Therefore, the
invokation of the compiler should be as follows:

$ gcc -g -lm [...]

in order to link with the math library, but it doesn't work for me even
though the headers <math.h> are included in 'automated_scanner.c'

Aitor.

Note.- I'm using the latest version in your git repository.
