Compiling +------------ + +net-snmp 5.3.1 and later have been compiled successfully on IRIX 6.5 using the +MIPSpro C compiler 7.4.4m in C99 mode: + + CC=c99 ./configure && make && make install + +Please note that the "host" module doesn't compile on IRIX, so you *cannot* +configure with "--with-mib-modules=host". + +Compiling with gcc may be possible, but is unsupported at this point in time +due to difficulties with the IRIX system headers. Brent Bice has reported +a successful build of net-snmp 5.4 with gcc 3.4.6 on a IP30 machine using: + + CFLAGS="-D_PAGESZ=16384 -D_MIPS3_ADDRSPACE -DIP30 -DR10000 -DMP \ + -DCELL_PREPARE -DBHV_PREPARE" ./configure ... + +See http://techpubs.sgi.com/library/tpl/cgi-bin/getdoc.cgi/0620/bks/\ +SGI_Developer/books/DevDriver_PG/sgi_html/ch10.html and +/var/sysgen/Makefile.kernio . + +2. CPU stats +------------ + +net-snmp 5.4.1 and later reports CPU statistics on IRIX 6.x by default using +the hardware/cpu/cpu_sysinfo module. There's also an alternative implementation: +hardware/cpu/cpu_pcp. For full discussion and build instructions for cpu_pcp +see Patch #1675869: + + http://sf.net/support/tracker.php?aid=1675869 + + +3. Perl +------- + +When compiling with Perl support, it's recommended to specify + + ./configure --enable-as-needed + +for proper libperl linking. + + +4. Known Issues +--------------- + +Accessing certain MIB objects on IRIX64 machines (i.e. when running a 64-bit +kernel will trigger nlist/klookup errors. The agent will not return proper +values for the affected MIB objects (e.g. tcpConnTable, udpTable). +Starting from net-snmp 5.4, you can avoid nlist altogether (recommended for +IRIX64) by using + + ./configure --without-kmem-usage ... + + +5. Feedback +----------- + +Please also see README and PORTING. + +If you have questions, additional insights or (even better) patches regarding +net-snmp on IRIX, please refer to the net-snmp mailing lists (see +http://www.net-snmp.org/lists). -- cgit v1.2.3
