On Linux FC2 with mySQL 4.1, I'm trying to compile a very simple C
by using GCC, but I get this error message:

[root@pc]# gcc -o hello -I'/usr/src/redhat/BUILD/mysql-4.1.9/include/'
-L'/usr/lib/mysql' -lmysqlclient -lz -lcrypt -lnsl -lm hello.c
/usr/bin/ld: cannot find -lmysqlclient
collect2: ld returned 1 exit status

I checked:
[root@pc]# /sbin/ldconfig -v | grep libmysqlclient
libmysqlclient_r.so.10 -> libmysqlclient_r.so.10.0.0
libmysqlclient.so.10 -> libmysqlclient.so.10.0.0

[root@pc]# echo $LD_LIBRARY_PATH

[root@pc]# find . -name "*libmysqlclient*"

What could I doing wrong? Regards.
