Also being hit by this: https://github.com/google-deepmind/mujoco_mpc/actions/runs/6644237828/job/18052982016 I think this is only affecting C++20 builds. |

Oh yeah, it does only affect C++20 builds, the STL headers shouldn't touch consteval and friends if building for an earlier standard version. |

Same issue for us :/ https://github.com/PedestrianDynamics/jupedsim/actions/runs/6645042045/job/18055479382 I noticed that after the image upgrade clang-15 is available but not the default clang, is this related? Also gradual rollout fine and dandy but how am I supposed to select a newly added clang version if it is random if I get an old or new image? Should I just |
You can use the LLVM Ubuntu repository as a workaround until this is fixed. You can make it install clang-17 like here: https://github.com/wheremyfoodat/Panda3DS/blob/master/.github/workflows/Linux_Build.yml Note that the |

thank you for the report. we'll have a look |

Maybe an anecdote, but one solution I tried (that didn't work, but seems like it should) was: Having Setting It seems that Anyway, since GCC 12 + 13 and clang 15 can currently be installed, pairing GCC 12 with clang 15 seems like an escape hatch but I wasn't personally able to get it working. edit: this comment's suggestion to use clang 17 seems promising as an alternative |

Same issue here on C++20: https://github.com/sourcemeta/jsontoolkit/actions/runs/6646548576/job/18060229938. Interestingly enough, the problem is not always reproducible. Retrying the same job a couple times makes it go away. |

Microsoft / Github seems to not care. Bad optics. |
|
The real treasure is the friends we made along the way while waiting 3 months for a fix |
Haha happy C++ coding everybody! We'll stand together even in the face of broken CI 😅 GitHub is us after all. |

Due to bug[0], on ubuntu, clang cannot #include <chrono> with -std=c++20. Switch it to c++17, compile with c++20 on macOS. Alternative solution: install latest clang on ubuntu, but that takes much more time to run. [0]: actions/runner-images#8659

Description
Some ubuntu-latest runners come with a newer version of libstdc++ and still have clang 14 which only has partial consteval support. As a result, trying to compile a file that does
#include <chrono>fails like this:Should be fixable by using clang 17.
Platforms affected
Runner images affected
Image version and build link
2.310.2
Link to a failing build: https://github.com/wheremyfoodat/Panda3DS/actions/runs/6640518979/job/18041094730
Ignore the "Setting up newer Clang" step in this run, the compilation step was still using the stock ubuntu-latest clang
Is it regression?
Yes (worked fine until yesterday: https://github.com/wheremyfoodat/Panda3DS/actions/runs/6614729350/job/17965319784)
Expected behavior
Runner clang should probably be able to compile this
Actual behavior
Some (not all) ubuntu-latest runners fail to compile C++ files that do
