Hi everyone,
I have combined "rtl_fm" with Thierry Leconte's (GPL'ed) acarsdec
library code and created "rtl_acars" which can directly decode ACARS flight info
messages to the console. Confirmed to compile on OSX 10.6 (not possible for me to check if
it also compiles under Windows and *nix). Feel free to add it as another proof of concept
to your distro unless you consider it too much of a quick&dirty hack.
Grab the code from: http://pastebin.com/kLJHyQWt
Best regards,
Andreas

Hey that's great news!
I just bought a rtl card for fun recently and subscribe to this list .
Very happy to see someone use my very old acars decoder code :-)
will try it very soon !

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,

Do you have the right access level to use the USB device? Try running
as the root user to see if that works. If not, see if you can use the
rtl_fm program first, and try rtl_acars again once rtl_fm is working.
(Just because Google will be more help for rtl_fm issues since more
people have used it.)
Cheers,
Adam.
