Public bug reported: Hi,
I've recently reported a linking problem #1727695, and as a workaround I've built the snap (https://github.com/hadmut/snap-rustc) on a 16.04 system and installed it on a 17.10. The linking problem does not occur then, but I run into another problem: % cargo build error: could not execute process `rustc -vV` (never executed) Caused by: No such file or directory (os error 2) Again a problem that did not occur under 16.04 and 17.04. Altough I can run rustc from the command line, cargo can't when run under 17.10. Unfortunately, and that's what's making things really difficult to debug, I cannot strace the process. strace as a regular user is not possible with snap binaries, since snaps cannot be straced as regular users. Running strace as root, on the other hand, completely freezes the process. No clue why cargo cannot run the rust compiler when run as a snap under 17.10. This problem does not occur, when running cargo directly as /snap/rust/x1/usr/local/bin/cargo build It then can run rustc (because it uses it's own path to find binaries and thus starts rustc from within the snap and not /snap/bin), but not cc as a linker. snapd and snapcraft are just too buggy to be usable under 17.10.
