Pls let me know which linkline is missing here.
Even i tried including '-lc' option still the same issue.

Never do this, remove -lc since added by the driver.

Do you know where those functions are defined and what they do?
You can search mass quantities by using:
nm -pxAN lib-paths | grep -e if_indextoname -e setlinebuf

[jagobbur]

This function shall map an interface index to its corresponding name.

After running nm command it says file or directory not found.
bash-3.00$ nm -pxAN lib-paths | grep -e if_indextoname -e setlinebuf
/usr/local/packages/compiler/usr/ccs/lbin/nm32: No such file or directory

[Dennis Handly]

Ok, there is a man page for each.
if_indextoname(3) says to use -lipv6, unless on 11.31.
setlinebuf(3) seems to be in libc but why would you use it instead of Standard setvbuf(3)? It seems to only be in 11.31.

[Dennis Handly]

>nm -pxAN lib-paths | grep -e if_indextoname -e setlinebuf
>/usr/local/packages/compiler/usr/ccs/lbin/nm32: No such file or directory

You need to replace lib-paths to something like /usr/lib/lib*

nm(1) is in /usr/ccs/bin. Make sure it is in your PATH before the foreign devil /usr/local/bin.

First symbol I am able to resolve by adding linklin option "-lipv6"
I need help on second sumbol i.e.ld: Unsatisfied symbol "setlinebuf" in file objects/prod/NetMonitor.c.o

[jagobbur]

I am going to use 'setvbuf' instead of 'setlinebuf' is that fine?
