syntastic integration does not seem to work with workspaces

[sdroege]

Running rust.vim on e.g. https://github.com/sdroege/gstreamer-rs and saving e.g. gstreamer/src/lib.rs will give a syntastic error:

syntastic: error: exception running system('cd /home/slomo/Projects/rust/gstreamer-rs/gstreamer && cargo check '): Vim(let):E484: Cannot open file /tmp/v4Hn0xR/5

Running cargo check in the workspace root or inside the gstreamer sub-crate works fine. I assume the latter is what should happen.

syntastic works fine on other crates that are not workspaces.

Hi!

Is this latest version of rust.vim on which system? I tried to reproduce the issue with gstreamer/src/lib.rs inside and https://github.com/sdroege/gstreamer-rs , however it seems to work fine. I've tested with Vim-Plug, using only Syntastic and rust.vim as plugins, on Vim 8.

That's with latest rust.vim (git master as of today), vim 8.1, syntastic (git master as of today) and both installed in ~/.vim/bundle

It may be a problem unrelated to rust.vim: https://groups.google.com/forum/#!topic/vim_use/SOtvjCOr7_Q

That mentions setting $TMPDIR to some other place but that has no effect for me. If e.g. it tries to use /tmp/v4Hn0xR/5 then /tmp/v4Hn0xR exists but there's not 5 in there.

Only syntastic on Rust workspaces has this problem for me, normal crates and other languages work fine

I'm not getting any errors but vim/syntastic doesn't make use of the advantage of a workspace. When I open a source file it triggers cd my-home/my-workspace/my-crate && cargo check. I would expect it to do cd my-home/my-workspace && cargo check. Is this configurable?

RTFM solved it for me:

 let g:rust_cargo_avoid_whole_workspace = 0

Not sure but this might be the better default.
