error: could not compile `sled` (lib) due to 1 previous error
It seems like shadowsocks-rust is using sled which is using atomic-shim to support atomic on mips and powerpc CPUs.
But atomic-shim is only enabled on mips and powerpc targets, but ARMv5TE and a bunch of other architectures also don't have AtomicI64.
There are some issues about this problem:
atomic-shim/issues/4
sled/issues/1070
There are also pull requests for these problems, but these projects are no longer maintained actively, so possibly they will never be merged.
sled/pull/1494
atomic-shim/pull/5
I'm not familiar with rust so I can't solve it myself. Please help solving this.
