Chakracore: [OS X] ChakraCore is built against different SDK than Rust which prevents linking ChakraCore into Rust projects

[dilijev]

See https://github.com/Microsoft/ChakraCore/issues/1441#issuecomment-242277297

FYI @fishrock123

[obastemur]

1493 should take care of this.

[dilijev]

@Fishrock123 Can you confirm whether this issue was fixed for you by #1493 ?

[obastemur]

Closing this one for now. From the discussion at #1493 there should be other things to consider (no longer SDK difference)

@Fishrock123 once you can share the steps, please open up an issue with the details so we may look into. Thanks!

[obastemur]

Prepared the bash script below for anyone looking into calling ChakraCore from Rust

CHAKRA_BUILD_FOLDER=$1

if [ ! -d $CHAKRA_BUILD_FOLDER ]; then
  echo "usage: compile.sh <path to ChakraCore BuildLinux folder>"
  exit 0
fi

@obastemur Still trying to get around to this again... some day.

How is this script intended to be used?

[obastemur]

@Fishrock123 Compile the rust file i.e. HelloWorld.rs into helloWorld.o and run the script above. It will link all of them into a single binary.

[dilijev]

@obastemur @liminzhu Is there any place for a script like that in the wiki, samples, or other documentation, so it doesn't just get lost in this issue?

[obastemur]

@dilijev unless we don't put a working rust sample and keep track of it, I don't think it is a good idea to locate such script to our wiki or any other official document.

Sample script above, I just wanted to clear out couple of tricky steps for people interested using ChakraCore from Rust. Search engines should lead to this page whenever they need it.

[dilijev]

@obastemur fair enough. Anything we can do to make this easier to find for people looking for this? I guess searching our issues for "Rust" is enough.

[darfink]

I will try to have my build script up to date, but right now it is automated and works on Windows, macOS & Linux (all tested on x64 static & dynamic).
Besides linking it also generates an interface file of the entire API usable in Rust.

For any rustaceans interested: https://github.com/darfink/chakracore-rs/tree/master/chakracore-sys
It will be published on Crates.io this week.

[obastemur]

@darfink I haven't tested but sounds really good! Thanks!
