Somehow my error logs have data in them toralf's lacked. ( I suspect due to ANSI colors doing the wrong thing somewhere: > memcache.c: In function ‘mcm_server_connect’: > memcache.c:2209:42: error: dereferencing pointer to incomplete type ‘struct addrinfo’ > if (ms->hostinfo == NULL || ms->hostinfo->ai_addrlen == 0) { > ^ > memcache.c: In function ‘mcm_server_resolve’: > memcache.c:2597:19: error: storage size of ‘hints’ isn’t known > struct addrinfo hints, *res; > ^ > memcache.c:2613:24: error: invalid application of ‘sizeof’ to incomplete type ‘struct addrinfo’ > bzero(&hints, sizeof(struct addrinfo)); > ^ HTH. (In reply to Kent Fredric from comment #4) oops, does the following not what do expect ? : function stresc() { perl -ne 's/\e\[?.*?[\@-~]//g; print' } I do use it in htis manner : "stresc < $log > $bak" often (In reply to Toralf Förster from comment #5) > (In reply to Kent Fredric from comment #4) > oops, does the following not what do expect ? : > > function stresc() { > perl -ne 's/\e\[?.*?[\@-~]//g; print' > } > > > I do use it in htis manner : "stresc < $log > $bak" often You probably want > perl -MTerm::ANSIColor=colorstrip -nle 'print colorstrip($_)' ( Its a much tighter regex internally that only matches numbers and ";" in escape codes ) Running your code locally as follows however gives me the right output, so I'm not sure where/why those values were eaten. > zcat /var/log/portage/build/dev-libs/libmemcache-1.4.0_rc2-r1\:20160306-102048.log.gz | perl -ne 's/\e\[?.*?[\@-~]//g; print' Looking deeper into your log, may actually be having different compiler errors (because I see not all types in error conditions are eaten, only some are) , just they're too similar to tell.

This is a parallel make issue. Building with MAKEOPTS="-j1 -pipe" works. Correction: well, at least that worked for me. (In reply to Livid from comment #11) -j1 is hard coded in the tinderbox My guess is that newer glibc headers do not like memcache.c playing around with glibc internal __USE_POSIX. *** Bug 593354 has been marked as a duplicate of this bug. *** I find that adding "#define __USE_XOPEN2K" to the memcache.c file above #include <netdb.h> resolves this build issue. I do not know what should be passed on the command line to force this. Created attachment 450882 [details, diff]
Patch for libmemcached-1.4.0
glibc headers need some feature test macros to expose the definition of
struct addrinfo. _XOPEN_SOURCE does not work, but _XOPEN_SOURCE 700
does. So this patch adds the feature test macro, and removes the hackery.
I have the same error.
