Re: GNU Linker problem with Dapper

I've been using Dapper for some time now, but never written code till
now. And today, just as I started learning about libnet, I hit a
roadblock.

I have gcc, g++ versions 4.0 and 3.4 installed, along with libnet1 and
libnet1-dev, all installed through apt (synaptic actually :)).

However when I try to compile any programs with libnet, each instance
of a libnet function in the code gives me this kind of error:

Terminal Output Begins
spectre@TheHotChilipepper:~$ gcc-3.4 libnet_learn_1.c
/tmp/ccmaIgZz.o: In function `main':libnet_learn_1.c:(.text+0x39):
undefined reference to `libnet_init'
:libnet_learn_1.c:(.text+0x4d): undefined reference to `libnet_destroy'
collect2: ld returned 1 exit status
Terminal Output Ends

/usr/include/libnet.h and the /usr/include/libnet directories _are_ there.

For the linker the header files are irrelevant at the point the error
message is issued.

Whats wrong then? Never seen this happen in Fedora (my last distro)
or elsewhere.

gcc -lnet libnet_learn_1.c
^^^^^
