[Nagiosplug-devel] compiling check_icmp on Solaris 5.9

[Stephan Janosch]

Hi guys!

I compiled plugins 1.4 on a solaris (SunOS <hostname> 5.9 
Generic_117171-15 sun4u sparc SUNW,UltraAX-i2 ) box. Following error 
occured:


# make
make  all-recursive
Making all in intl
Making all in lib
make  all-am
Making all in plugins
gcc  -g -O2  -L. -o check_icmp  check_icmp.o  ../intl/libintl.a -liconv 
-lgen -lsocket

*** Error code 1

Sorry for the linebreaks. These three symbols could not be found, 
because they are defined in _libnsl_. So I did following:

I added "-lnsl" to the "gcc-line":

# gcc  -g -O2  -L. -o check_icmp  check_icmp.o  ../intl/libintl.a 
-liconv -lgen -lsocket -lnsl

Then check_icmp was complied succesfully.

I hope, that helps on future issues with check_icmp.
Best regards, Stephan
