[Nagiosplug-help] check_radius compiling problem for Solaris

[Daniel Rubio]

Hi!

I'm trying to compile the check_radius plug in a Solaris 8 system using 
gcc3.1 (./configure --with-as=/usr/ccs/bin/as --with-ld=/usr/ccs/bin/ld 
--disable-nls).
I'm vaving the following problem (make all):

...
gcc -Wall -g  -c log.c
gcc  -o check_radius check_radius.o md5.o util.o \
        dict.o attrprint.o log.o
Undefined                       first referenced
 symbol                             in file
socket                              check_radius.o
gethostbyname                       util.o
bind                                check_radius.o
getservbyname                       check_radius.o
gethostbyaddr                       util.o
sendto                              check_radius.o
recvfrom                            check_radius.o
ld: fatal: Symbol referencing errors. No output written to check_radius
collect2: ld returned 1 exit status
make: *** [check_radius] Error 1

I've'nt idea where could be the problem ... anyone can help?
