We ran into the same problem on Ubuntu Wily (15.10). PHP reports:
php: symbol lookup error: /usr/local/lib/php/extensions/no-debug-non-zts-20090626/memcache.so: undefined symbol: mmc_queue_pop

While memcache compiles I'm seeing a bunch of errors like this:
/tmp/pear/temp/memcache/memcache_pool.h:395:12: warning: inline function ‘mmc_prepare_key’ declared but never defined
 inline int mmc_prepare_key(zval *, char *, unsigned int *);

/tmp/pear/temp/memcache/memcache_pool.h:394:12: warning: inline function ‘mmc_prepare_key_ex’ declared but never defined
 inline int mmc_prepare_key_ex(const char *, unsigned int, char *, unsigned int *);

After applying this patch (https://build.opensuse.org/package/view_file?expand=1&file=memcache-faulty-inline.diff&package=php5-pecl-memcache&project=home%3Agerritbeine%3Aforwards&rev=003162ef3cab7469fdcdf1430fd123a1) the problem goes away.

Ubuntu Wily uses GCC 5 and it seems that the semantics for inline functions have changed: https://gcc.gnu.org/gcc-5/porting_to.html (see section "Different semantics for inline functions")

Workaround:

You can alternatively install the extension and pass a new CFLAGS option to tell gcc to use the old method of inlining functions:

CFLAGS="-fgnu89-inline" pecl install memcache-3.0.7

The official bug tracker for PECL/memcache is now at
<https://github.com/websupport-sk/pecl-memcache/issues>.

So, if this is still an issue with either of the current memcache
versions (4 or 8), please file an issue there.
