source viewer problem

[peter7891]

Hello,

I have the problem where the source viewer only works for main.rs and any other code is unavailable.

The error is can't find source code for selected symbol

I tried this with one of my other projects, it works for the other project but not this one.
This is very weird.

[peter7891]

The only difference between the 2 projects is, the one that is not working is a workspace with multiple crates.

to be honest I'm really not sure how this feature works; I imagine that the debug symbols for the binary include a source map, and maybe the paths are wrong in the context of a workspace?

This thread on the same problem has a comment from 2018 saying "It appears the AT_decl_file entries for C++ code have absolute pathnames while the entries for Rust have relative pathnames."

Someone more recently said that running dsymutil fixed it, but it didn't for me.

After running dsymutil, in Instruments picking File -> Symbols, then Add Symbols (in the top middle of the window) -> Individual symbols, then the dsym file found at like target/release/mybinary.dSYM made the source show!
