Question

I have been trying to install libnids (Ubuntu LTS and Mac OS X) all the day and now I know how to compile programs with it.

I write this here because there is not much documentation but there are samples in the libnids downloaded folder with a makefile. The important things of this makefile are these:

CC = gcc    
PCAPLIB     = -lpcap    
LNETLIB     = -lnet    
LIBS        = -L../src -lnids $(PCAPLIB) $(LNETLIB) -lgthread-2.0 -lnsl

example:
    $(CC) example.c -o example $(LIBS)

And if you’re compiling it in Mac OS X ignore this: -lgthread-2.0 -lnsl -L../src
But I don’t know if something stop to works because of these omitted things.

Answer 1

I found it. The best way is to compile the library and then use local reference to the “.a” file.

Makefile example

CC = gcc -g -Wall 
GLIB =  `pkg-config --cflags --libs glib-2.0`
PCAPLIB     = -lpcap
LNETLIB     = -lnet

LIBS_SRC    = libnids-1.24/src/libnids.a
LIBS        = $(PCAPLIB) $(LNETLIB) -lgthread-2.0 

program: program.c
    $(CC) -c $(CFLAGS) program.c -o program.o $(GLIB) $(LIBS)
    $(CC) program.o  -o program $(LIBS_SRC) $(GLIB) $(LIBS)

But if you want to compile the library and install it into your system you got to use -lnids instead of the above way. But the first solution always works.
