compiler-explorer / clang-builder

Clang Compiler build scripts

The repository is part of the Compiler Explorer project. It builds the docker images used to build the various clang compilers used on the site.

To Test

This assumes you have set up your user account to be able to run docker without being root; if you haven't done so, you'll need to prefix these commands with sudo.

• docker build --build-arg image=22.04 -t clangbuilder .
• docker run clangbuilder ./build.sh trunk

Alternative to run (for better debugging)

• docker run -t -i clangbuilder bash
• ./build.sh trunk

clang-builder's Issues

clang-patmat fails to build

https://github.com/compiler-explorer/compiler-workflows/actions/runs/4613460554/jobs/8155454203

llvm master branch is now main

https://lists.llvm.org/pipermail/llvm-dev/2020-November/146615.html

There is a mirror in place until January 7th, at which point the master reference will disappear from llvm/llvm-project

kill s3cmd

Failed to build clangbuild docker

When I run:

sudo docker build -t clangbuilder .

in the source tree. The output shows error report:

Sending build context to Docker daemon    255kB
Step 1 : ARG image
Please provide a source image with `from` prior to commit

It looks like that I need to pass an image argument to it but I don't know how should I pass it.

My docker version is 20.10.6

---

And if I change the DockerFile to

# ARG image
FROM ubuntu:22.04
...

I received:

manifest unknown: OCI index found, but accept header does not support OCI indexes

I am on CentOS7.

@Sameeranjoshi - do you know who to talk to about this?
