building a statically linked version of memcached

[Harry Duin]

I want to build a statically linked version of memcached, but am not
able to accomplish this. I got the dynamically linked version to build
right away. To get the static build, I did this:

1. configure --with-libevent=/data/webserver_pkgs/target/dist/
libevent/
2. update Makefile to add the parameter -static to the LDFLAGS

but that results in:

gcc -std=gnu99 -g -O2 -pthread -Wall -Werror -pedantic -Wmissing-
prototypes -Wmissing-declarations -Wredundant-decls -L/data/
webserver_pkgs/target/dist/libevent//lib -static -o memcached

Does anyone have a suggestion to make this work? Thanks,

Harry

Add -lrt to LDFLAGS :)

After adding -lrt I still see these errors:

Did you remove -levent??

I did this by adding --disable-shared when building libevent, and then memcached with
./configure --with-libevent=<xxx> LDFLAGS=-lrt

I got this to work today as follows:

1. got latest libevent from: http://www.monkey.org/~provos/libevent/
2. build libevent as follows:
(cd in libevent directory first)
a. configure --prefix=/home/hduin/ots/libevent-1.4.13-build
b. make install
3. in latest memcached directory:
a. configure --with-libevent=/home/hduin/ots/libevent-1.4.13-build
b. edit Makefile and add -static to LDFLAGS and -lrt to LIBS
definitions
c. make

Based on these steps, I thought for sure that the following configure
would work so I would not need to edit the Makefile, but this did not
work. The configure fails on this: LIBS="-lrt" LDFLAGS="-static" ./
configure --with-libevent=/home/hduin/ots/libevent-1.4.13-build

Oh well, I got the static build!

If you add: --disable-shared

It would have worked because it would not find a shared version of the library. Modern linkers will try to use a shared object if it finds one unless you tell it to use a static one.
