To pull the image, use docker pull nobodyxu/llvm-toolchain:tag.

How to build

To build it on your only computer that is not x86_64 architecture, you need to run

echo -e "FROM debian:buster\nRUN mkdir -p /opt/llvm/src" | docker build -f - --tag=nobodyxu/llvm-toolchain:stage1

before running make (a technique to save compilation time by reusing previous build).

On x86_64 architecture, just run make.

Proxy for apt and git during the build

During the build, the port 8000 and 8080 is being checked for accessibility. If these port is on, the build will assume the apt and git proxy respectively is up on your computer.

• To specify a different port, pass environment variable APT_PROXY_PORT and GIT_PROXY_PORT respectively when invoking make.
• To specify a different host, pass environment variable APT_PROXY_HOST and GIT_PROXY_HOST respectively when invoking make.
• To use no proxy, pass environment variable NO_APT_PROXY and NO_GIT_PROXY respectively when invoking make.
