This package doesn't build without commit 626b8c0f6aa2101802a93653bbd18651999caaf1

@MasterDuke, could you please update this to v0.5.4? Both 0.5.2 and 0.5.3 contained a serious bug where the FUSE driver would hang when reading files in the mounted filesystem. Thanks!

0.5.3 installed with no trouble or intervention on my part, many thanks!

I've patched the PKGBUILD to work with the v0.5.3 release that fixes the issue. It builds nicely on my RPi, so I reckon it's fine to enable the aarch64 arch. I've removed a few dependencies that aren't needed. Also, I'm pretty certain the sparsehash dependency can be dropped (but I only spotted that now).

Thanks for maintaining this build!

Hi, author here. I've just reproduced this on my Arch Raspberry Pi. It seems I wasn't expecting the source tarball to be built from within a different git repo, so the code that auto-generates the version files will try to pull the information from the outside git repo, which isn't a good idea. I've got a fix for this, it'll be part of the next release.

Ah ha, the lpthread business was a red herring. I believe the actual problem happens very early on when cmake is running git describe --tags --match "v*" --dirty, but since this is just a shallow clone without any tags it dies with fatal: No names found, cannot describe anything. I tried deepening the clone, but that didn't bring in any tags, so I just manually added a v1.4.0 tag (whoops, that should have been v0.4.0) and then makepkg -irs succeeded.

Can confirm @MasterDuke's problem, 0.3.1-2 won't build.

There's a missing -lpthread somewhere. If I copy out the failed test file and try to compile it manually g++ test_pthread.cpp I get the same error, but if I do g++ -lpthread test_pthread.cpp it succeeds.

I'm getting an error when building 0.3.1-2.
