Building StegoTorus on Darwin

We describe the build process for a clean (modulo XCode, developer commandline tools, emacs, xquartz, iterm2, and homebrew) install of Mac OS X 10.9.5.

We use clang++.

1. Install the prerequisites:

>brew install git autoconf automake libjpeg pkg-config openssl libevent jansson

(if libevent fails to "link" try changing the ownership on /usr/local/lib/pkgconfig)

2. Clone the repositories.

>git clone https://github.com/SRI-CSL/jel.git
>git clone https://github.com/SRI-CSL/stegotorus.git

3. Build and install jel

>cd jel
>autoreconf -i
>./configure --enable-silent-rules
>make
>sudo make install

4. Build StegoTorus

>cd stegotorus
>autoreconf -i

Overide apple's deprecation of openssl:

>export libcrypto_LIBS="-L/usr/local/opt/openssl/lib -lcrypto"
>export libcrypto_CFLAGS=-I/usr/local/opt/openssl/include

>./configure --enable-silent-rules
>make

If this produces linking errors (e.g., on Mac OS X 10.8.5) one can also use clang as the compiler:

>CC=clang CXX=clang++ ./configure
...
checking for gcc... clang
...
>make

5. Testing StegoTorus

1. Install the prerequisites

  ```

brew install tor ```

2. Make sure you can bootstrap tor:

  ```

cd stegotorus tor -f data/torrc ```

 If this bootstrap OK, then kill tor, and remove the cache:

  ```

rm -rf ~/.tor ```

3. Now in two windows start stegotorus

  ```

./modus_operandi/start-client-vm06 ```

 and then in the other window, start tor, note we are using a different

configuration file.

  ```

tor -f data/stegotorrc ```

This should bootstrap but will no doubt be slower than bootstrapping

directly.
