Free Radius Compilation problem

Hi All, I am compiling the free radius server code on Linux kernel 2.4.20. I wanted to use it for the text file authentication. I am getting the error as follows: sql_mysql.c:39:20: errmsg.h: No such file or directory sql_mysql.c:40:19: mysql.h: No such file or directory gmake[10]: *** [sql_mysql.o] Error 1 gmake[9]: *** [common] Error 2 gmake[8]: *** [static] Error 2 gmake[7]: *** [common] Error 2 gmake[6]: *** [static] Error 2 gmake[5]: *** [common] Error 2 gmake[4]: *** [all] Error 2 gmake[3]: *** [common] Error 2 gmake[2]: *** [all] Error 2 gmake[1]: *** [common] Error 2 make: *** [all] Error 2 Whether it is configuration problem or library proble. Help needed. Thanks in advance. Regards, Wable R. U.
