We have been trying to build bsnmpd 1.12 on freebsd 5.3 but have many weird issues building snmp_bridge, snmp_hostres & snmp_mibII modules. The errors seem to come from compiler strictness cc -fpic -DPIC -O -pipe -I/work2/vrajan/head/products/rapid/freebsd5/src/usr.sbin/bsnmpd/modules/snmp_mibII/../../../../contrib/bsnmp/lib -I/work2/vrajan/head/products/rapid/freebsd5/src/usr.sbin/bsnmpd/modules/snmp_mibII/../../../../contrib/bsnmp/snmpd -DHAVE_ERR_H -DHAVE_GETADDRINFO -DHAVE_STRLCPY -DHAVE_SYS_TREE_H -I. -Wsystem-headers -Werror -Wall -Wno-format-y2k -W -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Wreturn-type -Wcast-qual -Wwrite-strings -Wswitch -Wshadow -Wcast-align -Wchar-subscripts -Winline -Wnested-externs -Wredundant-decls -c /work2/vrajan/head/products/rapid/freebsd5/src/usr.sbin/bsnmpd/modules/snmp_mibII/../../../../contrib/bsnmp/snmp_mibII/mibII_route.c -o mibII_route.So /work2/vrajan/head/products/rapid/freebsd5/src/usr.sbin/bsnmpd/modules/snmp_mibII/../../../../contrib/bsnmp/snmp_mibII/mibII_route.c: In function `sroutes_RB_INSERT_COLOR': /work2/vrajan/head/products/rapid/freebsd5/src/usr.sbin/bsnmpd/modules/snmp_mibII/../../../../contrib/bsnmp/snmp_mibII/mibII_route.c:516: warning: empty body in an if-statement /work2/vrajan/head/products/rapid/freebsd5/src/usr.sbin/bsnmpd/modules/snmp_mibII/../../../../contrib/bsnmp/snmp_mibII/mibII_route.c:516: warning: empty body in an if-statement /work2/vrajan/head/products/rapid/freebsd5/src/usr.sbin/bsnmpd/modules/snmp_mibII/../../../../contrib/bsnmp/snmp_mibII/mibII_route.c:516: warning: empty body in an if-statement /work2/vrajan/head/products/rapid/freebsd5/src/usr.sbin/bsnmpd/modules/snmp_mibII/../../../../contrib/bsnmp/snmp_mibII/mibII_route.c:516: warning: empty body in an if-statement /work2/vrajan/head/products/rapid/freebsd5/src/usr.sbin/bsnmpd/modules/snmp_mibII/../../../../contrib/bsnmp/snmp_mibII/mibII_route.c: In function `sroutes_RB_REMOVE_COLOR': /work2/vrajan/head/products/rapid/freebsd5/src/usr.sbin/bsnmpd/modules/snmp_mibII/../../../../contrib/bsnmp/snmp_mibII/mibII_route.c:516: warning: empty body in an if-statement /work2/vrajan/head/products/rapid/freebsd5/src/usr.sbin/bsnmpd/modules/snmp_mibII/../../../../contrib/bsnmp/snmp_mibII/mibII_route.c:516: warning: empty body in an if-statement /work2/vrajan/head/products/rapid/freebsd5/src/usr.sbin/bsnmpd/modules/snmp_mibII/../../../../contrib/bsnmp/snmp_mibII/mibII_route.c:516: warning: empty body in an if-statement /work2/vrajan/head/products/rapid/freebsd5/src/usr.sbin/bsnmpd/modules/snmp_mibII/../../../../contrib/bsnmp/snmp_mibII/mibII_route.c:516: warning: empty body in an if-statement /work2/vrajan/head/products/rapid/freebsd5/src/usr.sbin/bsnmpd/modules/snmp_mibII/../../../../contrib/bsnmp/snmp_mibII/mibII_route.c:516: warning: empty body in an if-statement /work2/vrajan/head/products/rapid/freebsd5/src/usr.sbin/bsnmpd/modules/snmp_mibII/../../../../contrib/bsnmp/snmp_mibII/mibII_route.c:516: warning: empty body in an if-statement How could the following line in freebsd5/src/usr.sbin/bsnmpd/modules/snmp_mibII/../../../../contrib/bsnmp/snmp_mibII/mibII_route.c throw so many errors? RB_GENERATE(sroutes, sroute, link, sroute_compare); We have not been successful in using the gcc -E option to get preprocessed code to analyze the issue. Any help will be appreciated.
