Hi, I installed libc-client and libc-client-devel RPMs using yum update. Everything went fine. However, the header file shortsym.h installed in /usr/include/imap/ has all these short symbols defined which are not found... where are these? For instance, here are the errors: #define auth_link a_link #define auth_log a_log #define auth_login_client al_cli #define auth_login_server al_ser #define auth_md5 a_md5 #define auth_md5_valid a5_val #define auth_md5_client a5_cli #define auth_md5_server a5_ser #define auth_pla a_pla #define auth_plain_valid ap_val #define auth_plain_client ap_cli #define auth_plain_server ap_ser #define authenticate a_auth #define authserver_login a_serv #define body_encodings bencds #define body_types btypes #define compare_csizedtext cm_szt #define compare_cstring cm_str #define compare_ulong cm_uln #define default_proto d_prot #define dummy_append d_appn ...... My question is where are all these a_link, al_cli, al_ser, a_log, a_md5, etc defined? I can not find it in any header file on my system....however the install was clean. Thanks for any pointers, and best wishes! __________________________________ Do you Yahoo!? Yahoo! Mail - Easier than ever with enhanced search. Learn more. http://info.mail.yahoo.com/mail_250
