Bad parameter -pthread being used on Solaris (instead of -pthreads)

[GoogleCodeExporter]

What steps will reproduce the problem?
1.
  On SunOS (see below for my particular version), installed libevent-1.4.13:
   cd libevent-1.4.13-stable/
   ./configure
   make
   make install

2. Configure and make memcached:
   cd memcached-1.4.4/
     ./configure --with-libevent=/root/libevent-1.4.13-stable
     make

3. Notice the warnings about -pthread:
   gcc: unrecognized option `-pthread'

The first time I compiled it, I did not notice this problem in make, and I
installed anyways.  The result was that I could not reliably cache any
value > 7K.  At 7+K the cache would start failing.

To fix it, I edited memcached-1.4.4/configure and changed -pthread to
-pthreads (plural for SunOS).  That worked, and fixed my max value for
cache size to 1MB as it should be.

I believe this is a problem in ./configure for memcached.

Thanks,

According to http://gcc.gnu.org/onlinedocs/gcc/Option-Summary.html both 
-pthread 
and -pthreads should work on SPARC. 

What is the gcc-version you are using?

Had same issue trying to compile on solaris, memcached-1.4.4 and gcc (GCC) 
3.4.3 (csl-sol210-3_4-
20050802).

Guess you should try a newer version of gcc (according to 
http://gcc.gnu.org/gcc-3.4/ 
3.4.3 was released in 2004...) I just tried to compile memcached with gcc 4.4.1 
on a 
T5240 running Solaris 10, and I didn't get a single warning from gcc.

Yep, I was using gcc 3.4.3:

[root@mem-01.rent.com ~]$ gcc -v

Just wanted to add a quick note that Sun Solaris comes with gcc 3.4.3, and even 
sunfreeware.com only provides gcc-3.4.6 as an alternative.

Basically if we don't fix this in configure to support gcc 3.4.x, many people 
who 
get Solaris and don't specifically upgrade gcc themselves might have the 
problem I 
encoutered.

The real issue is that 'gcc: unrecognized option `-pthread'' is a warning and 
not an 
error.  If the person compiling memcached ignores that warning or does not 
notice 
it, and installs memcached, the results are insiduous (cache failures at small 
cache 
sizes etc...).

It's much easier to add this one-liner to your build script than to install a 
recent gcc on Solaris 

perl -p -i -e 's/-pthread"/-pthreads"/g' configure

Can't support old versions of gcc anymore. we're moving on.
