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:
|
|
|
|

|
|
|
|
|
|
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 ...
|
|
|
|
