I updated and installed libc-client and libc-client-devel to version 2002e-17, then recompile the package for squirrelmail plugin serversidefilter. The errors about mail.h and 2002e-17 are gone, but I got the following warnings and errors (too long, I cut it): gcc -c filtercmd.c -DSQUIRRELMAILCONFIGFILE='"/etc/squirrelmail/config.php"' gcc -c checkcreds_cclient.c -I/usr/include/imap '-DMAIL_H="mail.h"' '-DLINKAGE_C="linkage.c"' -DIMAP_TIMEOUT=2 checkcreds_cclient.c: In function âmm_loginâ: checkcreds_cclient.c:84: warning: incompatible implicit declaration of built-in function âstrncpyâ gcc -o filtercmd filtercmd.o checkcreds_cclient.o /usr/lib/c-client.a -lssl -lpam -L/usr/lib/ -lgssapi_krb5 -lcrypt -lkrb5 -lresolv -lcom_err -ldl -lz -lcrypto -lk5crypto -static /usr/lib//libpam.a(pam_handlers.o)(.text+0x9d0): In function `_pam_parse_conf_file': : warning: Using 'dlopen' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking ...

What should I do to fix the error? Thanks! Hongwei
