Some notes for the IRIX port ============================ 1. 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. 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 ... 3. 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).
