Request for Relative Paths

[Platin21]

Is your feature request related to a problem? Please describe. The feature I request is the ability to add rpath's to frameworks and so/lib/dylib files so that the can be relative to some point and are not required to be inside the runtime linker search path.

This is something that is only for Linux and MacOS interesting.

• For MacOS it's because of .app's requiring the lib's to be internal in the .app container and signed if it's not a system library
• For Linux there are similar executable containers that make this maybe interesting also the commands are roughly the same.

Describe the solution you'd like My Proposal would be something in that ballpark:

foreign import libclang "libclang@app/libs/"

The other option would be to have a relative path search path flag added to the compiler:

odin build main.odin -relative_path="@app/libs/"

I'm not sure which of these two ways is better but one thing that is important is to change the nameingconvention of the relative identifiers as writing out @executable_path and so on is pretty awful. My proposal in that regard would be to have:

@app = @executable_path (on macOS this actually points to the .app folder) @bin = @loader_path (this points to the folder containing the actual binary this can be set for libraries and also executables)

Couldn't we overload the collection system to do this? Like how system is reserved. We could have system_app and system_bin.

[Platin21]

As in -collection=MyLib:@bin/lib thing is just it's not really per library that's what sucks a bit about it. Like one doesn't need to add a rpath to each library they added.

Or did you mean we just collect all the paths and add them once and depending how one does do system_app or system_bin ?

So say for example:

foreign import clang "system_app:/lib/libclang" 

Would still required one to define somehow the system_app path as it doesn't need to be the same every time. E.g “one cannot just simply” for this that path and for that this path with the from you proposed way.

Github bot again..

I’ll make a pr with both versions and let’s see what feels better we can certainly add a rpath flag..

Bump.
