Please rebase against latest main and add an entry to the matrix in |

rebasing is done, I'll look into adding clang |

Added Clang support, I hope it works (we'll see after the workflow run has been approved) |
|
Please add a clang Release build too. You can just change config in the matrix entry to |

ok, done, also rebased against current main |

Must be Debug,Release. No spaces and no trailing comma.

Please fix. I want to get this merged.

Unfortunately it is still not working. The env. var. CONFIGURATION is only being set to Debug. I think you need single quotes when setting the matrix value:
config: 'Debug,Release',

doesn't work either

I just duplicated the clang section now, once for Release and once for Debug

It complains a lot about non-final classes (structs) derived from KVEntry having virtual functions but no virtual destructor, which in std::optional code (that explicitly calls the destructor somewhere) could theoretically lead to the wrong destructor being called (that of the struct directly derived from KVEntry instead of the one of a hypothetical class derived from that struct that might actually need its destructor called). This doesn't matter in practice because 1. those classes don't have any implemented constructors that need to do anything 2. no further classes are derived from those that are derived from KVEntry So (I think!) these warnings are only hypothetical, but still annoying. Apparently this does not happen if Clang uses libc++ or MSVCs C++ stdlib (in the ClangCL case), but only with libstdc++, maybe even only with libstdc++ from GCC14, but that's the only version I have on my machine. fixes KhronosGroup#1011

Sorry about all the troubles. This workflow needs to use the "Ninja Multi-Config" generator for the multi-config builds to work. The separate matrix entries you have just added are good for now. I'll work on converting to "Ninja Multi-Config" later. |

Thank you for your hard work on this. |
