OpenWRT Mac OSX SDK & Toolchain

OpenWRT (trunk version for x86) and Carambola2 (v2.8) SDK and Toolchain development binaries can be found at http://mehmetalierturk.com/openwrt for Mac OSX (El Capitan). Binaries contain main developments packages  as preinstalled (gcc & gdb) and others packed under packages subdir.


Building OpenWRT on Mac OS X 10.10 Yosemite

After upgrading to Yosemite, I have to rebuild OpenWRT for new os. Here is the complete steps to build OpenWRT on Mac OS X 10.10 Yosemite. I tested it both Carambola 2 native and OpenWRT x86 architectures.

First, you need a disk image on your mac. Go to Disk Utiliy->New Image-> Case sensitive, sparse disk Image. I allocate 15GB to work on 2 different builds.

Second, install XCode from App Store, and Command Line Tools:

xcode-select --install

Then, install macports (clean install is needed) and update:

sudo port selfupdate

Install required ports:

sudo port install gcc47 coreutils asciidoc bzip2 fastjar flex getopt gtk2 intltool jikes zlib openssl p5-extutils-makemaker rsync ruby sdcc unzip gettext libxslt bison gawk autoconf wget gmake ncurses e2fsprogs ossp-uuid gawk findutils gnutar

Everything is ready to get the source code and build. Mount the disk we setup in the first step and cd into and get OpenWRT.

git clone git://git.openwrt.org/14.07/openwrt.git

clang can build everything from scratch.

gcc -v

Configured with: –prefix=/Applications/Xcode.app/Contents/Developer/usr –with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 6.0 (clang-600.0.54) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin14.0.0
Thread model: posix

export PATH=/opt/local/libexec/gnubin:/opt/local/bin:${PATH}

Setup your firmware options:

make menuconfig

and build:

make -j 8

Configure Eclipse NS3 on Mac OS X 10.10 Yosemite

To get ns3 running with Mac OS X 10.10 Yosemite:

Configure Development Environment

  1. Download Xcode from Apple App Store https://itunes.apple.com/tr/app/xcode/id497799835?mt=12
  2. Install Xcode
  3. Download and install command line tools. You can type `xcode-select –install` terminal or https://developer.apple.com/downloads/index.action
  4. gdb 7 has some problems with on Mac OS X so, install gdb 6 with macports using `sudo port install gdb-apple` or homebrew
  5. Download ns3 source code using web site http://www.nsnam.org or get with mercuriel `hg clone http://code.nsnam.org/ns-3-dev`
  6. Change ns3 directory and run `./waf -d debug configure`

Configure Eclipse

  1. Download Eclipse IDE for C/C++ Developers from http://www.eclipse.org/downloads/
  2. From eclipse New->New Project select C++ Project
  3. Point location of the ns3 and name it
  4. Right click on the project and properties, C/C++ Build change build command to waf `${workspace_loc:/NS3Dev}/waf` and build directory to `${workspace_loc:/NS3Dev}/build`
  5. Change incremental build all to build
  6. Now build project
  7. If you get unnecessary errors,from Eclipse Preferences->C/C++->Code Analysis uncheck Syntax and Semantic Erros

Signing gdb

Mac OS X requires gdb to be signed to access memory locations so:

  1. Open Keychain Access, Keychain Access->Certificate Assistant->Create a Certificate…
  2. Name the cert as `gdb-cert` select `Self Signed Root` and `Code Signing` also check override defaults
  3. Next, until “Specify a Location The Certificate” and select `System`
  4. Find cert in Keychain Access and if its not trusted trust the cert.
  5. From terminal sign the gdb `sudo codesign -s gdb-cert $(which gdb)`

Configure Eclipse Debugger

  1. Debug Configurations add new configuration
  2. Select C/C++ Application from list `build/scratch/scratch-simulator`
  3. In Environmental’s tab select new and add `DYLD_LIBRARY_PATH` variable and `${workspace_loc:/NS3Dev}/build` value
  4. In debug section select debugger path to gdb

Fixing OMNET++ on Mac OS X 10.9 Mavericks

Upgrading to Mac OS X 10.9 Mavericks breaks OMNET++, some actions required to get it working correctly. Here is the steps that I followed;

  1. Install latest Xcode 5.0.1 from Mac App Store
  2. Install command line tools  xcode-select –install
  3. Install macports Mavericks build
  4. Install gcc version 4.7 via macports
    sudo port selfupdate
    sudo port install gcc47
    sudo port select –set gcc mp-gcc47
    After this point you can compile OMNET++ and get working but, I faced problems when running simulations like missing icons/images in simulation. I think Tcl library has issues with Mavericks, in my case it has to reinstall too.
  5. sudo port install tcl
    sudo port install tcllib
  6. Now, edit configure.user in OMNET++ source directory
    CC=gcc-mp-4.7
    CXX=g++-mp-4.7
    TK_LIBS=”-L/opt/local/lib -ltk8.6 -ltcl8.6″
  7. Now you can follow OMNET++ standard installation instructions.
    ./configure
    make

 


Simulating Wireless Sensor Network with OMNet++ on Mac OS X Lion

There are several network simulators available which are design for different purposes. Quick google will result survey papers discussing these simulator both advantages, disadvantages and usage areas. After deep diving into these simulator environments, OMNeT++ is the best logical option for simulating WSN (Wireless Sensor Networks). OMNeT++ is available as commercial and academic uses and actively developed.

Also, OMNeT++ provides infrastructure to develop components top off on it and WSN is available as 3rd party component. OMNeT++ models are available in its website. Mixim is a modeling framework for mobility and fixed networks which is necessary simulating wireless networks with OMNeT++.

OMNeT++ 4.2.1 and MiXiM 2.2.1 is greatly integrated and works well under Mac OS X Lion. After installing OMNeT++ MiXiM is imported into workspace and compiled under OMNeT++. To be able to compile and build tools latest XCode version is needed.
