Hi, I had the same problem..
I did 3 modifications to solution the problem.
One is to comment the variable that show the error.
here is in line modem_run.c:94
now see the variable verbose
? add a value 0 to it.
Now, when u do that.. it will show another error.. similar the other error..
Just do the same thig, but now with another variable..
Now u can compile the program.. but i my modem woudnt connect.. i dont know why..
I dont find anything on internet that anyone connected speedtouch 330 at slack12..
