having Problem to compile Openflow module

Hi, I'm recently use NS3 simulator to develop my program, for my program I need openflow module to work with NS-3. So I follow the instruction https://www.nsnam.org/docs/release/3.25/models/html/openflow-switch.html to install openflow and cope it with NS-3. But I met problems from the very first step, the OS I use is OS X Yosemite:

So the very first problem I met is here:

The OFSID requires libxml2 (for MPLS FIB xml file parsing), libdl (for address fault checking), and boost (for assert) libraries to be installed.

I can't find any port of libdl to port it using macport and when I googled, it looks like it is a library of Oracle solaris system... so if I don't have this library anything will go wrong with the integration of NS-3 and openflow?

And the second problem I met is here:

Obtain the OFSID code. An ns-3 specific OFSID branch is provided to ensure operation with ns-3. Use mercurial to download this branch and waf to build the library:
```
$ hg clone http://code.nsnam.org/openflow
$ cd openflow
```
From the “openflow” directory, run:
```
$ ./waf configure
$ ./waf build
```

So I successfully downloaded this branch and try to build it, and I got prompted with some problems:

1. the very first one is "conflicting types for 'strlcpy'",

Waf: Leaving directory `/Users/Effi/openflow/build'

Build failed:

-> task failed (err #1):

-> task failed (err #1):

{task: cc daemon.c -> daemon_1.o}

-> task failed (err #1):

{task: cc dhcp.c -> dhcp_1.o}

I googled and looked at the header file, and found a definition with this function, so I think its just because the header file want to check if a function call 'strlcpy' exists(util.h file line 106-108), if not, it will define it, which according to the error message I got, it seems that my system library already have this function, but the #ifndef line works not so great so it thinks it is a duplicate definition. So I comment out this three lines to get things work, which it works and the compilation proceeds to next few files and I got another problem:

2.

which appears that problem exists in xtoxll.h, which its contents :

#ifndef XTOXLL_H

#define XTOXLL_H 1

#include <arpa/inet.h>

#include <sys/types.h>

static inline uint64_t

htonll(uint64_t n)

{

return htonl(1) == 1 ? n : ((uint64_t) htonl(n) << 32) | htonl(n >> 32);

}

static inline uint64_t

ntohll(uint64_t n)

{

return htonl(1) == 1 ? n : ((uint64_t) ntohl(n) << 32) | ntohl(n >> 32);

}

#endif /* xtoxll.h */

I did not see anything wrong here, so I can't find any solution to solve it... anyone can help?

Hi,

I'm not a 100% sure about that, but the openflow module won't work on mac.

I would try compiling it inside a VM running Linux.

Cheers,

Luciano.

Did you find a solution to this problem? This is what I'm facing.

2 warnings and 3 errors generated.

Hi, I currently did not find any solution of this and I just decided not to be bothered by this as it would be a later objective of my project. If you are still facing the problem, try install a virtual machine of Linux, though it may not be a good solution. But wasting time of figuring out what goes wrong of Mac and this module just don't worth it... At least from my perspective.

Hi All,

Did anyone get to build Openflow on Mac OS-X?

I have gotten the error messages below. I also checked the file xtoxll.h, but I didn´t get to finding out an error.
