Compilation with MySQL 5.0

[Rodolfo Gonzalez Gonzalez]

Hi,

I'm trying to compile cyrus-sasl-2.1.21 with MySQL 5.0.18 but configure 
says:

--- start ---
checking SQL... enabled
checking for mysql_select_db in -lmysqlclient... no
configure: WARNING: MySQL library mysqlclient does not work
--- end ---

config.log shows:

--- start ---
configure:11589: checking for mysql_select_db in -lmysqlclient
configure:11620: gcc -o conftest -Wall -W -O3 -mtune=nocona 
-I/usr/include/mysql -O3 -mtune=nocona
-I/usr/include/mysql -I/usr/include/mysql -L/usr/lib/mysql 
-lmysqlclient -lcrypt -L/usr/lib/mysql
-Wl,-rpath,/usr/lib/mysql conftest.c -lmysqlclient >&5
/usr/lib/mysql/libmysqlclient.a(my_compress.o)(.text+0xdd): In function 
`my_compress_alloc':: undefined reference to 
`compress'/usr/lib/mysql/libmysqlclient.a(my_compress.o)(.text+0x180): In 
function `my_uncompress':: undefined reference to `uncompress'
collect2: ld returned 1 exit status
--- end ---

The mysql libraries come from the mysql.com generic linux RPM's. I guess 
this problem has something to do with a conflict between the system's zlib 
and the mysql's zlib. I haven't tested recompiling MySQL but first I 
wanted to know if someone else had the problem. The configure line was:

LDFLAGS="-L/usr/lib/mysql -lmysqlclient -lcrypt" \
CFLAGS="-O3 -mtune=nocona -I/usr/include/mysql" \
CPPFLAGS="-O3 -mtune=nocona -I/usr/include/mysql" \
./configure \
   --enable-login \
   --enable-sql \
   --with-mysql=/usr \
   --with-authdaemond=/var/lib/sasl \
   --with-saslauthd=/var/run/sasl \
