Description:
After unpacking mysql-5.5.7-rc.tar.gz i executed configure script.

While compilation I got error in libmysql:

client_plugin.c:354: error: âRTLD_NOWâ undeclared (first use in this function)

I fixed it by defining HAVE_DLOPEN 1 in my_config.h

But then I am getting linking errors

client_plugin.c:(.text+0x361): undefined reference to `dlopen'
client_plugin.c:(.text+0x37d): undefined reference to `dlsym'
client_plugin.c:(.text+0x46f): undefined reference to `dlclose'

How to repeat:
build with 

" ./configure --prefix=/usr/local/mysql-5.5.7-rc CFLAGS="-O3 -m32 -march=core2 -mtune=core2 -fomit-frame-pointer -pipe -fno-exceptions" CXXFLAGS="-O3 -m32 -march=core2 -mtune=core2 -fomit-frame-pointer -pipe -fno-exceptions" --enable-assembler --disable-shared --with-mysqld-ldflags=-all-static --with-client-ldflags=-all-static --with-plugins=innobase --without-debug CXX=gcc --with-comment="Build 5.6.7-rc x32"  --enable-thread-safe-client

Changing client/Makefile 
From
   LIBS = -lcrypt -lnsl -lm -lz
To
   LIBS = -lcrypt -lnsl -lm -lz -ldl

Fixed this problem

Thank you for the report.

I can not repeat described behavior. Which version of gcc do you use?

I got the same error on Debian 6.0 (squeeze) gcc (Debian 4.4.5-8) 4.4.5

Thank you for the feedback.

Please try with current version 5.5.8 and inform us if problem still exists.
