`cargo install cargo-xbuild` fails with noexec /tmp mount #90

Closed ChaiTRex closed 3 years ago

ChaiTRex commented 3 years ago

There are many systems out there with a noexec /tmp mount. The current cargo install cargo-xbuild will fail to work on all of them.

$ mount | fgrep /tmp
tmpfs on /tmp type tmpfs (rw,nosuid,nodev,noexec,noatime)

$ cargo install cargo-xbuild

Unfortunately, this is an issue with the cargo install command itself: https://github.com/rust-lang/cargo/issues/4350

So there is nothing specific to the cargo-xbuild crate that is causing this issue, apart from using a dependency that has a build script. I'm therefore closing this issue in favor of the linked cargo issue because there is nothing we can do about it from our side. For the short term, maybe the workaround described in https://github.com/rust-lang/cargo/issues/4350#issuecomment-340215811 helps.
