Compiling Dynamips on Intel Mac + Leopard.
by David Sudjiman ~ December 16th, 2007. Filed under: Cisco, Mac.This article is a continuity from my previous article.
As I’ve upgrade my MBP from Tiger to Leopard, some adjustment needs to be made.
Installing XCode 3.0
If you get the Leopard CD, you can install XCode 3.0 from it. Go to Optional Install - Xcode Tools - and run XcodeTools.mpkg to install.
Or you can also download it from http://developer.apple.com/tools/download/. You need to get Apple Developer Connection to get it.
Installing X11 SDK
This package is installed by default when you have Leopard on your machine. However, if you need to install X11 SDK, you can use Leopard CD. Go to Optional Install - Xcode Tools - Packages - and run X11SDK.mpkg to install.
MacPorts
Get this MacPorts-1.5.0-10.5.dmg and install it.
Update your port list.
sudo port -v selfupdate
Install libpcap
$ sudo port install libpcap $ sudo ln -s /opt/usr/local/libpcap.a /usr/local/lib/libpcap.a
Instal libelf
$ sudo port install libelf
Download the latest Dynamips 0.2.8-RC2 source code and install it.
$ curl 'http://www.ipflow.utc.fr/dynamips/dynamips-0.2.8-RC2.tar.gz' -o dynamips-0.2.8-RC2.tar.gz $ tar -zxvf dynamips-0.2.8-RC2.tar.gz $ cd dynamips-0.2.8-RC2 $ make $ mv dynamips dynamips-0.2.8-RC2.intel-mac.bin $ strip dynamips-0.2.8-RC2.intel-mac.bin
Greg has put his Dynamips compiled on Leopard. You can download this binary from here

Saya menggunakan GNS-3, bisa juga menggunakan dynamips namun masih gagal di “emulate mode”
masih ingat saya?

Wisperwind,
After getting libelf from ports as well, you need to create these additional links in order for the compiler to find them:
$ sudo ln -s /opt/local/include/libelf /usr/include/libelf
$ sudo ln -s /opt/local/include/libelf.h /usr/include/libelf.h
After this & instructions from David, I ran the make without any problems.
