Original GitHub issue: https://github.com/deepseek-ai/3FS/issues/87

I started a container of Ubuntu:22.04 on WSL2, and build 3FS following the guide. But the compiler complained about consteval error.

Here is the related log:

        _S_fractional_width()

Other environment infomation:
Clang 14.0
Host Nixos 24.11 on WSL2

I will try clang-17 later and paste the result.

Quick Reply:
I changed to clang-18, and it seems that everything is well. But I modified dome codes:

CMakeLists.txt(top level): remove '-fcoroutine-ts'.
remove -Werror
some compiler errors.(easy to fix)

The progress completes 30%, and I will paste the following result later.

Compilation complete, but some modifications are made. I'm not sure whether these modifications preserve the semantic, as some of them are probable breaking changes. I haven't tested the binaries, and have no idea about it works.

Here are my patches for references, of which some modifications are absolutely redundant.

0001-build-change-to-clang-18.patch
0001-build-clickhouse-change-to-clang-18.patch
0001-build-folly-change-to-clang-18.patch
0001-build-jemalloc-change-to-clang-18.patch
0001-build-leveldb-change-to-clang-18.patch
0001-build-rocksdb-change-to-clang-18.patch

Anyway, it works on my computer.

A hotfix: modification of executor.setNumthreads() is wrong. It is supposed to be preserved.
