Hi I am trying to use SNMP to monitor FreeRadius 1.0.4 server installed on a solaris 10 machine. When I run the configure scripts, I see error message for snmp.h, asn1.h and snmp_impl.h saying either update these header files or compile with --enable-ucd-snmp-compatibility option. I searched the mailing list and found that I can comment out the ifdef is these header files, which include the net-snmp header files. I made those changes and now when I run the configure script the I get following error message in config.log file: configure:8336: checking for asn1.h,snmp.h,snmp_impl.h configure:8364: gcc -c -g -O2 -D_REENTRANT -D_POSIX_PTHREAD_SEMANTICS -DOPENSSL_ NO_KRB5 -Wall -D_GNU_SOURCE -DNDEBUG conftest.c 1>&5 configure: In function `main': configure:8360: warning: unused variable `a' configure:8533: checking for snmp_build_var_op in -lsnmp configure:8545: gcc -o conftest -g -O2 -D_REENTRANT -D_POSIX_PTHREAD_SEMANTICS - DOPENSSL_NO_KRB5 -Wall -D_GNU_SOURCE -DNDEBUG conftest.c -lnsl -lresolv -lso cket -lposix4 -lpthread -lcrypto -lssl -lsnmp 1>&5 ld: fatal: library -lsnmp: not found ld: fatal: File processing errors.

I have following .so files in /usr/sfw/lib directory. libnetsnmp.so libnetsnmpagent.so libnetsnmphelpers.so libnetsnmpmibs.so snmp/lib/libnetsnmp.so And the /usr/sfw/lib directory is in both PATH and LD_LIBRARY_PATH variables. Can some one please tell me what do I do to get this damn thing working. Any pointers/procedures to get snmp based monitoring of radius server up is r most welcome. Thanks in advance. -Vishwa.
