| 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 ... |
