Dear MaFai: If you make sure your configuration is right. There maybe anthor problem. It is about your sql driver. I have met this problem before when I setup Oracle database.
You can check the driver in "FreeRadius_Root/src/modules/rlm_sql/drivers/rlm_sql_mysql", modify the Makefile so that all environment variable in correct , rebuild the driver , and go up to FreeRadius root directory, then make , make install again. Following is my Makefile about mysql driver, may it be helpful # Generated automatically from Makefile.in by configure. include ../../../../../Make.inc TARGET = rlm_sql_mysql SRCS = sql_mysql.c RLM_SQL_CFLAGS = $(INCLTDL) RLM_SQL_LIBS = -L/usr/lib -lmysqlclient -lm -lnsl -lresolv -lsocket -lposix4 -lpthread -lz include ../rules.mak Sincerely, Albert - List info/subscribe/unsubscribe?
