Failing to build or install py-spy on Mac OS 13

[jrabinow]

I'm trying to build py-spy to add it to MacPorts, but I seem to be running into an issue with libproc.
Machine info:

macOS 13.3 22E252 arm64
Xcode 14.3 14E222b

When attempting to cargo install, I get the following error:

$ cargo install py-spy
error: failed to run custom build command for `libproc v0.12.0`

Caused by:

My attempt at a macports port seems to be running into an issue with libproc as well:
macports_build.txt

Any ideas on how I could get py-spy to build?

[benfred]

it looks like libproc is failing to build here w/ fatal error: 'libproc.h' file not found .

This seems to be the same error as andrewdavidmackenzie/libproc-rs#82 .

I just built successfully on my OSX system, but I'm still on Catalina (and on an intel based machine).

Thanks for linking both issues, I reported my issue upstream along with a patch. I'm not sure how long it'll take to fix or what functionality is included in the libproc library - asking with zero context here, does it make sense to try to remove the dependency on libproc-rs?
If not, it might make sense to close this issue since it looks like the problem is upstream

[benfred]

does it make sense to try to remove the dependency on libproc-rs?

py-spy isn't actually using libproc directly, libproc is being used by the remoteprocess and proc-maps dependencies of py-spy. the remoteprocess dependency is using it to get the exe/cwd https://github.com/benfred/remoteprocess/blob/70509587992eead0fdeb5534125c8ac7db2ce9a8/src/osx/mod.rs#L50-L62 - and proc-maps is using it to get the filename for a region of memory https://github.com/rbspy/proc-maps/blob/6d6fcb987fe663a7232b90a4182feb0dfc7c1f4c/src/mac_maps/mod.rs#L146 .

We could replace it in both cases, but ideally we'd just get it fixed upstream.

[jrabinow]

Both libproc-rs and proc-maps have released new versions with the fix

[jrabinow]

Hi @benfred would it be possible to release a new version of py-spy including the upstream fix from libproc-rs?
