[ENet-discuss] Enet Installation and C++

[Charlie Sibbach]

Hey all,

Well, I'm stumped. I thought it was simply my inexperience with UNIX,
but after my guru friend spent a few hours and couldn't get it working
either, I have to turn to the list.
Here's the problem. After downloading the source, and following the
build instructions in the README, I got Enet installed on my Mandriva
Linux installation. Next, I create a basic hello world program to make
sure it's getting linked in correctly. That program is this:

#include <iostream>
#include <enet.h>
using namespace std;

int main() {
	enet_initialize();
	cout << "Hello, cocksucker!" << endl;
	enet_deinitialize();
	return 0;
	}

I compile it thus:
g++ -I/usr/local/include/enet -L/usr/local/lib hello.cpp

This program produces about a hundred errors. Such as:

If I convert it to a straight C file and just use gcc with this invocation:
gcc -I/usr/local/include/enet -L/usr/local/lib -lenet hello.c

 I still get errors, but this time from the linker:
/home/masamune/tmp/ccGMkZMM.o(.text+0x1d): In function `main':
: undefined reference to `enet_initialize'
/home/masamune/tmp/ccGMkZMM.o(.text+0x32): In function `main':
: undefined reference to `enet_deinitialize'
collect2: ld returned 1 exit status

If you're still there, the question of the day is what gives? My
friend and I spent at least two hours playing with configuration
scripts, variables and other stuff I don't yet understand; and this is
the best we could do. We want to use Enet in a C++ project, and all
the headers seem to have adequate protections for this, so I don't
think that's the problem. Is it possibly a Mandrake/Mandriva issue?

Any and all advice here is much appreciated!
