error: incremental compilation: could not create session directory lock file: Input/output error (os error 5)

[allenzhao64]

I tried this code:

$ cargo build

some other observation:

The cargo build works only when using a local device path.

cargo build --release works fine,

The file is hosted on a NFS device

[ms140569]

I'm facing this issue when compiling anything hosted on my SAMBA/SMB Fileserver (rather than NFS)

This is:
Mac OSX 10.14.6
rustc 1.48.0 (7eac88a 2020-11-16)

my workaround is to either disable incremental compilation or work on a local APFS Filesystem ...

Caused by:

The source for the panic is:

 872         let incr_comp_session = self.incr_comp_session.borrow();

[ehuss]

#85698 has changed it so that rustc does not panic in this situation, but it will still generate an error.

I'm going to close this as a duplicate of #49773 to consolidate the issues related to session locking.
