Submodules should be cloned recursively. Try git clone --recursive RepoURL.

Submodules should be cloned recursively. Try git clone --recursive RepoURL.

I didn't clone the repo recursively, but latter I use this command:

git submodule update --init --recursive

I think it's equivalent? I will reclone your repo recursively to try if it help.

It turned out the two commands are not equivalent. Cloned the repo recursively and cmake configuration done. But build failed:

Please note that only MSVC and clang++ in Linux were tested. Using other compilers or environments is theoretically feasible, but there may be some minor issues that need to be fixed.

The endian.h is not available on Windows. agz-utils uses it for endian determination in gnu environment. Please remove the gnu macros in agz-utils/misc/endian.h.

As for std::aligned_alloc, It appears that mingw64 doesn't provide the std::aligned_alloc function in C++17. However, there is a workaround using _aligned_malloc on Windows. You can try changing AGZ_CC_MSVC in agz-utils/alloc/alloc.h to match mingw64.

I may attempt to fix the compilation issues on mingw later.

Doing as you said, but run into another problem:
