There are including head file rpcsvc/ypclnt.h in c. files, such as nis-ethers.c. But no rpcsvc folder under src.
Also no rpc, netinet, arpa, sys.

#include <rpc/types.h>
#include <rpcsvc/ypclnt.h>

#include <netinet/in.h>
#include <arpa/inet.h>

#include <sys/param.h>

Build errors with:

nis-hosts.c:39:10: fatal error: 'resolv/mapv4v6addr.h' file not found
#include <resolv/mapv4v6addr.h>
^~~~~~~~~~~~~~~~~~~~~~
This seems to be a private header, not installed by default in glibc.

I'm using a Linux embedded device with Yocto and I added mdns directly from Apple sources.
It contains a patch http://cgit.openembedded.org/meta-openembedded/tree/meta-networking/recipes-protocols/mdns/files/0001-nss_mdns-Do-not-include-nss.h-when-libc-glibc.patch?h=master to bypass nss.

Is this package required to use mdns (fully implemented in a standard way to pass certification procedures) or is it optional?

thank you.

Hello,

f152663 made __libc_once to just set ONCE_CONTROL. This is not only non-portable (pthread_once_t is not necessarily an integer), but it is also completely unsafe: there is no guarantee of INIT_FUNCTION to be called only once if several threads call __libc_once. To keep things safe without depending on libpthread, pthread_once_t should be replaced by a structure containing an integer and a mutex, so that the mutex can be taken around the whole if. (libcs ususally provides hooks for pthread_mutex_lock/unlock)

For replacing the nss_nis module in glibc, we'd prefer if we could use a version number larger than 2.26, but we wouldn't want to override the upstream version. Would you be willing to make a new release, perhaps 2.99, or even 3.0?
