Hi all: I use vpopmail+mysql+sqwebmail,and have installed vopopmail+mysql. i think it is ok. then there is some problem when i install sqwebmail. i run ./configure --enalbe-authvchkpw --without-authpam --without-authuserdb --without-authpwd --without-authshadow --enable-webpass=no then run make there is some error massage like this: ... /usr/local/vpopmail-4.8.4/vauth.c 537:undefined reference to 'mysql_free_result' /home/vpopmail/lib/libvpopmail.a vuth.o):infunction'vopen_smtp_relay': /usr/local/vpopmail-4.8.4/vauth.c 563:undefined reference to 'mysql_query' /usr/local/vpopmail-4.8.4/vauth.c 584:undefined reference to 'mysql_query' . . . make[1]:***[authvchkpw] Error 1 make:***[all-recursive] Error 1 /usr/local/vpopmail-4.8.4 is the path i unzip the tar file /home/vpopmail is the path i install even if i delete the path /usr/local/vpopmail-4.8.4 ,the error is the same. i think maybe mysql lib path is wrong, but i try to copy the mysql lib file to /usr/lib . but it is of no effect. Today i reinstall Redhat6.2+qmail+mysql+vpopmail, it is all ok. when i install sqwebmail, it is the same error. i am very vey anxious and will appreciate for ur help. pls reply asap. [EMAIL PROTECTED]
