Steem OS X Build Instructions

1. Install XCode and its command line tools by following the instructions here: https://guide.macports.org/#installing.xcode. In OS X 10.11 (El Capitan) and newer, you will be prompted to install developer tools when running a devloper command in the terminal. This step may not be needed.

2. Install Homebrew by following the instructions here: http://brew.sh/

3. Initialize Homebrew:

   brew doctor
   brew update
   

4. Install dependencies:

   brew install boost cmake git openssl autoconf automake qt5
   brew link --force openssl 
   

5. Optional. To support importing Bitcoin wallet files:

   brew install berkeley-db
   

6. Optional. To use TCMalloc in LevelDB:

   brew install google-perftools
   

7. Clone the Graphene repository:

   git clone https://github.com/steemit/steem.git
   cd graphene
   

8. Build Steem:

   git submodule update --init --recursive
   cmake .
   make
   

Low Memory Mode

This mode reduces the amount of RAM it takes to build a validating node

cmake -DLOW_MEMORY_NODE=ON .

Content Patching

If you do not need an API server or to see the result of patching content then you can use this flag. This will also remove the dependency on Qt5

cmake -DENABLE_CONTENT_PATCHING=OFF .
