This library implements the core Bitcoin functionality for the AirBitz wallet. It manages accounts, syncing, and Bitcoin transactions.
Assuming your system has the necessary command-line tools installed, it should be possible to build an Android or iOS-compatible version of ABC by doing something like:
cd deps
make
This will automatically guess the type of build you want to do. If you would like to build for a specific platform, use one of the following inside the 'deps' directory:
make abc.build-android-arm
make abc.build-ios-universal (only works on a Mac)
make abc.build-native
The build process requires several pieces of software to be installed on the host system:
git wget autoconf automake libtool pkgconfig cmake
To install these on the Mac, please use Homebrew. The 'wget' and 'cmake' that come from MacPorts are known to be broken.
If you are building for iOS or Mac native, you also need a working installation of the XCode command-line tools. For Linux native builds, you need the clang compiler.
The 'deps' system automatically downloads and builds the various open-source libraries that the AirBitz core depends on. If you want to bypass the deps system and run 'make' directly from the top-level directory, you need to manually compile all these dependencies and install them on your system. This approach is a lot of work, but it makes sense if you often find yourself modifying the dependencies.
The entire library used to live in the "src" directory, but we are in the process of re-designing the library's API. The new (work-in-progress) library lives in the "abcd" directory, and the code in the "src" is just a shim that adapts the new library to the old API. Once the GUI's switch to the new API, the "src" directory will go away.
The "deps" directory contains a system for downloading and building all the libraries that ABC depends on, as well as ABC itself, for mobile platforms.
The "util" directory contains a set of command-line tools that exercise the core. We use these internally for debugging and testing.
The "server" directory contains the source code for our git replication utility. We run this on our sync servers each time a wallet pushes new data, copying the data to the other servers as well.
The "tests" directory contains some random test code. This is largely unmaintained, and doesn't even compile. We will scrap this once the command- line utilites in "util" are more complete, since those will allow us to do all the testing we need with some simple shell-script wrappers. We should also think about doing proper unit tests at some point in the future.
