Ah, OK. That's a different problem indeed.

Well, I just built rtptools with
http://autobuild.buildroot.org/toolchains/configs/br-arm-basic.config,
which does *not* have RPC support, and it builds fine. So it is not
simply that rtptools unconditionally needs RPC support. Looking at the
code, it does:

#ifndef __UCLIBC__
#define HAVE_YP
#endif

#ifdef HAVE_YP
#include <rpcsvc/ypclnt.h>   /* YP */
#endif


So it seems like it has special handling for uClibc. I think you should
replace this with an AC_CHECK_HEADERS test for rpcsvc/ypclnt.h, and use
the HAVE_<foo> variable that will be defined by this test.

Best regards,

Thomas
