Instructions are incomplete about flapigen-rs HOT 5 CLOSED

Hi, @spease!

error: Can not put/generate foreign lang helpers: update of c++\rust_interface\rust_str.h failed: the system cannot find the path specified. (os error 3)

I'm not sure what the proper way is to get past this error. It looks like I might be able to just copy the file over, but that seems rather inelegant and undesirable as my local copy would eventually fall out of sync with the library copy...

You don't need copy rust_str.h over, it is part of rust_swig binary (bundled as resource to rust_swig.rlib) so rust_swig always has it. The problem is in the path that you specify as output (c++\rust_interface\rust_str.h), rust_swig doesn't create directories for you, so you have to create them by hands or add to build.rs appropriate code.

Sorry, I don’t think I understand. You say they’re bundled with it, but I have to specify a path in build.rs. How do I specify a path to the resources? Is there an example somewhere?

You don't need to specify a path to the resource.
You actually should not care about rust_str.h at all.
I mean something wrong with output, not with input.

I mean that message:

error: Can not put/generate foreign lang helpers: update of c++\rust_interface\rust_str.h failed: the system cannot find the path specified. (os error 3)

tells you that something is wrong with "c++\rust_interface" directory,
it doesn't exist, or you use the wrong slash character (\ instead of /),
or this path is not relative to the root of the crate.

I attached a minimal example of a crate that works for me (cargo build).
Does it work for you?

foo.zip

There is now detailed documentation: https://dushistov.github.io/rust_swig/ ,
plus error message about not created directory I made more clear.
