Just tell me if I am been lazy but I can't find the argp.h file anywhere.
abacus:~/lego/lnpd+liblnp$ make depend
for i in lnpd liblnp applications ; do make -C $i depend || exit -1 ; done
make[1]: Entering directory `/home/mike/lego/lnpd+liblnp/lnpd'
gcc -M -I. rcxtty.c lnp.c logger.c transceiver.c daemon.c main.c > .depend
main.c:9: argp.h: No such file or directory
make[1]: *** [depend] Error 1
make[1]: Leaving directory `/home/mike/lego/lnpd+liblnp/lnpd'
make: *** [depend] Error 255
Thanks again.
