haessal/build-bitcoincore repository overview

⁠Bitcoin Core builder

The Dockerfile in this project is to assemble the container image for building Bitcoin Core⁠ v0.20.1. In the container, the required tools and libraries are installed according to UNIX BUILD NOTES⁠.

This container is designed to build command-line only bitcoin node, so libraries for GUI are not installed. To compile Berkeley DB 4.8 from source code and install it, this script⁠ is used.

⁠To build Bitcoin Core:

⁠Assemble the container image

$ docker image build -t builder .

In this description, builder is used as the name of the image.

⁠Clone Bitcoin Core source code

The builder assume that the target version of Bitcoin Core is v0.20.1.

$ cd /path/to/workdir
$ git clone [email protected]:bitcoin/bitcoin.git
$ cd bitcoin
$ git checkout -b v0.20.1 v0.20.1

⁠Run the container with the cloned Bitcoin Core source code

$ docker container run --rm -it -v `pwd`:/workspace builder

⁠Build Bitcoin Core (In the container)

# cd /workspace
# ./autogen.sh
# CXXFLAGS="-g -O0" CFLAGS="-g -O0" ./configure --without-gui
# make

The CXXFLAGS="-g -O0" CFLAGS="-g -O0" is not strictly necessary to build, but I offten run the configure script with these option because I want debug info to be included.

When the make complete, you can find src/bitcoind in workdir.
