Re: Libnet in FreeBSD
Question: do I need to set the cflag & libs options in the libnet-config file for the compiling and linking to happen correctly ?

Re: Libnet in FreeBSD
ok after that e-mail last night, I did try a make of the ports collection libnet after the make, everything looked fine, atleast I didnt notice anything missing in the log or config files but I still see the same problem, " undefined reference to libnet_init" and msgs liks that for every libnet call. I used -lnet too, but of no use, even did the changes in make file that mel had suggested in the previous post. So I dont know what the problem here is or if this is some incompatibility between how i have BSD and how I have libnet or probably they are not linking together or something like that. Otherwise I dont see why the compiler doesnt recognize any libnet function calls. Here is a question I have, I've worked in TinyOS before and I'm wondering if in Libnet we need a separate directory for each application with its own custom-written make file, or things can just be in one pool from where they are compiled. I do a simple cc -lnet filename.c compile. Is there something else I'm missing here ?

Re: Libnet in FreeBSD
Sorry I'm not getting this... what did u want me to try ? I'm not using the ports collection and have installed libnet 1.1.2.1 in root. Did u say I had to add these lines to the make-file of my app.c sample file or to the BSD make-file in usr/share/mk or is it something else ? .also my /usr/local/lib doesnt have any lib11 file like that. Just wanted to understand it before I tried it.

Hmm, that goes into BSD's make system, so read up on it: less /usr/share/mk/bsd.README also: gzcat /usr/share/doc/psd/12.pmake/paper.ascii.gz|less These are more general C-programming topics though, not specific for FreeBSD. I just gave you a BSD make example, cause I knew that'll work out of the box, but you can use other systems, like the GNU autotools + gmake or jam.

Re: Libnet in FreeBSD
Question: Do I need to do this for every libnet app I compile, like modify the PROG variable in the app's folder even for the sample aplications already compiled & set ? Aside this, if someone could tell me the exact compilation steps for Libnet, it would be really helpful.

Linking 101. If you used the port (/usr/ports/net/libnet) then: cc -L/usr/local/lib/libnet11 -lnet dns.c or: cat

Re: Libnet in FreeBSD
well actually, even the sample applications seem to have the same problem, So I'm guessing its some installation issue: # cc dns.c /var/tmp//ccImyVt1.o(.text+0x88) : In function 'main' : : undefined reference to 'libnet_init' This is how my compilation result reads for the dns.c sample application. Says the same for all libnet calls.

Could you show the entire compile line, you're likely to miss -L/usr/local, but there may be other things. Also helps to know what you use for you simple application: bsd's make with a Makefile, gmake with a Makefile or just type commands by hand. -- Mel ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
Libnet in FreeBSD
Hi, I'm trying to work with Libnet in BSD, I ftped the package, did a ./configure and a make install and things seemed to be fine. But when I try to compile a simple application, I get a msg : " undefined reference :libnet_init" , actually it looks like it doesnt recognize any of the libnet functions calls. Am I missing something here ? or is there something else to be done about getting libnet to run here ?
