For developers, there is also the option to download the full source code as a ZIP archive or by cloning the authoritative source repository from GitHub. Go to https://github.com/bitcoin/bitcoin and select "Download ZIP" from the sidebar. Alternatively, use the git command line to create a local copy of the source code on your system. In the following example, we are cloning the source code from a Unix-like command line, in Linux or Mac OS:

Carefully review the build pre-requisites which are in the first part of the build documentation. These are libraries that must be present on your system before you can begin to compile bitcoin. If these pre-requisites are missing the build process will fail with an error. If this happens because you missed a pre-requisite, you can install it and then resume the build process from where you left off. Assuming the pre-requisites are installed, we start the build process by generating a set of build scripts using the +autogen.sh+ script.

The Bitcoin Core build process was changed to use the autogen/configure/make system starting with version 0.9. Older versions use a simple Makefile and work slightly differently from the example below. Follow the instructions for the version you want to compile. The autogen/configure/make introduced in 0.9 is likely to be the build system used for all future versions of the code and is the system demonstrated in the examples below.

The +configure+ script allows you to enable or disable certain features of bitcoind through the use of the +--enable-FEATURE+ and +--disable-FEATURE+ flags, where +FEATURE+ is replaced by the feature name, as listed in the help output above. In this chapter, we will build the bitcoind client with all the default features.

If all goes well, the +configure+ command will end by creating the customized build scripts that will allow us to compile bitcoind. If there are any missing libraries or errors, the +configure+ command will terminate with an error instead of creating the build scripts as shown above. If an error occurs, it is most likely a missing or incompatible library. Review the build documentation again and make sure you install the missing pre-requisites. Then run +configure+ again and see if that fixes the error. Next, we will compile the source code, a process that can take up to an hour to complete. During the compilation process you should see output every few seconds or every few minutes, or an error if something goes wrong. The compilation process can be resumed at any time if interrupted.
