ggsn build problem

Harald I am trying to build the ggsn package so that openbsc can pick it up. I get the following errors when running autoreconf -i   sing `AC_PROG_RANLIB' is rendered obsolete by `AC_PROG_LIBTOOL' libtoolize: `config.guess' exists: use `--force' to overwrite libtoolize: `config.sub' exists: use `--force' to overwrite libtoolize: `ltmain.sh' exists: use `--force' to overwrite ggsn/Makefile.am: C objects in subdir but `AM_PROG_CC_C_O' not in `configure.in' ggsn/Makefile.am:9: required file `ggsn/getopt1.c' not found ggsn/Makefile.am:9: required file `ggsn/getopt.c' not found sgsnemu/Makefile.am: C objects in subdir but `AM_PROG_CC_C_O' not in `configure.in' sgsnemu/Makefile.am:9: required file `sgsnemu/getopt1.c' not found sgsnemu/Makefile.am:9: required file `sgsnemu/getopt.c' not found autoreconf: automake failed with exit status: 1   I am able to build libosmocore and openbsc fine though.   Naveen
