build error with localy built toolchain on macos x

[bentxt]

Like described under 'Installation' but for macos:

 curl -s -o ./.rust/rustup-init.tmp -- https://static.rust-lang.org/rustup/dist/x86_64-apple-darwin/rustup-init

With this resulting toolchain

which cargo
/Users/ben/builds/vonuvoli-scheme/vonuvoli-scheme/.rust/rustup/toolchains/nightly-x86_64-apple-darwin/bin/cargo

But it doesn't build

It seems there are some incompatibilities with OSX.

I'll try to fix the build for OSX in the weekend if I get some time.

However, you could quickly try to patch the code to fix these minor incompatibilities. (For example a (ext::libc::S_IFMT as u32) would work for some, and the other is just find the equivalent of RUSAGE_THREAD for OSX.

I also seem to have issue building on MacOS. This has not been fixed right?

@Machine-Jonte nop, not yet. (I mainly use Linux, thus I didn't cross-compile it for OSX, especially given how clumsy the whole Rust cross-compiling experience is.)

If you could try to fix the compile errors and let me know the patch that makes it work, I could try to put in some #cfg[...] items in the code to make it work.

Else, I'll have to find a weekend and make it work. (I've already experienced the Rust cross compiling to OSX on another project, I just need to port the scripts into this project.)

[Machine-Jonte]

@cipriancraciun I did some quick hackaround but not sure how to test out if it actually works.

I expected this to work (i.e. running cargo run --bin vonuvoli-scheme-interpreter ./examples/benchmark--controls.ss )

[cipriancraciun]

Yes, it compiles and works, just that the arguments of the interpreter are perhaps a bit counter-intuitive.

See the help at:

vonuvoli-scheme/documentation/tools/interpreter--help.txt

Lines 6 to 17 in e2d1a94

	--------------------------------------------------------------------------------
	---- How to execute scripts?
	vonuvoli-scheme-interpreter -s /.../script.ss [ script-argument ... ]
	vonuvoli-scheme-interpreter -c '(scheme code)' [ script-argument ... ]
	The first `--` argument terminates the parsing of interpreter arguments,
	and starts the script arguments; it is also removed from the resulting list.
	Note, that any argument after the `-s /.../script.ss` or `-c '(scheme code)'`
	is considered an argument for the script.
	However the first `--` is processed as described above.

Basically you need to use -s script.ss.

@Machine-Jonte if you happen to use Discord, there is a channel dedicated to this project https://discord.gg/WuCr5rzfq2, and it could perhaps work a bit better than back-and-forth on GitHub for smaller problems.
