My notes on developing changes to compiler-explorer

git clone https://github.com/mattgodbolt/compiler-explorer (or this)
git clone https://github.com/compiler-explorer/infra

Patch compiler-explorer-image/clang/Dockerfile, using some of the stuff from docker-compiler-explorer:

 COPY build /root/

Build and run docker:

docker build -t ce:v1 compiler-explorer-image/clang
docker run -it -p 10240:10240 -v ~/src/compiler-explorer-dev/infra:/infra -v ~/src/compiler-explorer-dev/built-compilers:/opt/compiler-explorer -v ~/src/compiler-explorer-dev/compiler-explorer:/compiler-explorer ce:v1

From within the docker instance, download some compilers:

./bin/ce_install list 'compilers/c++'
./bin/ce_install install 'compilers/c++/clang 11.0.0'

Still from within docker, build and run compiler-explorer itself:

cd /compiler-explorer
make
