Problem in installing Memcache in linux( RHEL)

[rajiv]

Hi All,
I am facing problem in installing memcache on RHEL. It is
giving error in Make command. I am pasting the error of the command
below. Please help me out.

mcached_debug-stats.o memcached_debug-util.o memcached_debug-cache.o -
lgcov -levent
/usr/bin/ld: cannot find -lgcov
collect2: ld returned 1 exit status
make[2]: *** [memcached-debug] Error 1
make[2]: Leaving directory `/root/memcached-1.4.1'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/root/memcached-1.4.1'
make: *** [all] Error 2

Please file an issue at http://code.google.com/p/memcached/issues/list

We don't have a builder running RHEL, so we cannot detect such
problems before releasing. If you would like us to test on RHEL during
development, please consider hosting a builder for us. For more
information about builders, check out: http://code.google.com/p/memcached/wiki/BuildFarm

To fix the build you are doing, pass --disable-coverage to configure.

Cheers,

Trond

Building either 1.4.0 on 1.4.1 on Centos 5 i386 yields following error

memcached.c:3845:1: error: embedding a directive within macro arguments is
not portable

Doing the same on Centos 5 x86_64 works fine. Fix is relatively simple.
Move out the #if defined out of printf e.g.

This looks helpful (though we don't have any builders that reproduce
it).

Please file a bug.

And in general, please don't use the reply button to start a new
topic. It's kind of rude to hijack someone else's thread for
something unrelated.

My mistake. I should have started a new message. Forgot about References.
