Adam, I've compiled rtl_acars.c with this:
gcc -o rtl_acars rtl_acars.c `pkg-config --cflags --libs librtlsdr libusb` -lpthread -lm
without any error. It produced an executable file named rtl_acars However when I enter ./rtl_acars -f 131550k I get this error message : bash: ./rtl_acars: Permission denied What can be wrong? I use ubuntu 12.04 (sorry I am new to Linux) Appreciate your help. Regards,
