@gaul commented on GitHub (Jul 25, 2024):

Sorry no one active on this project uses Windows so we cannot help you. @siketyan added the original MSYS support so maybe they have a suggestion? The error appears to be in the WinFsp header itself:

/home/Administrator/s3fs-fuse-master/WinFsp/inc/fuse/winfsp_fuse.h: In function ‘void* fsp_fuse_signal_thread(void*)’:
/home/Administrator/s3fs-fuse-master/WinFsp/inc/fuse/winfsp_fuse.h:342:14: error: ‘sigwait’ was not declared in this scope
  342 |     if (0 == sigwait((sigset_t *)psigmask, &sig))

so I suggest investigating why signal support is not working. I can submit a PR for some shallow issues but they won't address your main problem.

I am also not a Windows user for now but will try the compile instructions on this weekend.

I tried compiling s3fs-fuse on a fresh Windows + MSYS2 environment and here is what I learned:

  • libopenssl-devel is no longer available, use openssl-devel instead.
  • -I/usr/include compiler option is missing so we can't find any libc headers on compilation. Use make CXXFLAGS=-I/usr/include instead of make.
  • inc/fuse/winfsp_fuse.h is missing import of string.h for memset(). Add #include <string.h> at the top of the file.
  • fdcache_entity.cpp uses fallocate() but it's not available. We can use posix_fallocate() but I don't know it's enough to work or not.

After these considerations, I was able to finish the compile and .\s3fs.exe --version works!

@siketyan Thanks!

inc/fuse/winfsp_fuse.h is missing import of string.h for memset(). Add #include <string.h> at the top of the file.

Thanks. This issue can be resolved with a PR from @gaul, so I will merge it.

fdcache_entity.cpp uses fallocate() but it's not available. We can use posix_fallocate() but I don't know it's enough to work or not.

Thank you for noticing that fallocate is not available.
However, posix_fallocate cannot be used to replace fallocate.
To save space on the cache file, s3fs uses PUNCH HOLE(sparse file) instead of reserving the entire file size, thus fallocate is used.

I believe that this is fixed -- please reopen if this is not addressed. It would be great if someone could further improve Windows support and set up a CI task to avoid future breakage.
