Hello agn, another OM have the same problem. I read his question and the answer in packet radio. Try following and it works ufb: Change the following syntax in tnt.h #include <time.h> (old entry is #include <sys/time.h>) You can write the new line in front of the old one: ... #include <time.h> #include <sys/time.h> ... So it works well. Have nice hacking and gd link in packet radio, Tobias (DG2DBT)
