The build steps given on front page give me following errors-

Hi, when I copy and paste your command, I get the same error. Try deleting the command and manually typing it in. It could be an issue if you copied the command from a presentation or something, the - (U+002D) gets converted to a long – (U+2013) character, which is different.

[youngar]

It looks like the wrong dash character is baked into README.md.

[youngar]

Should be fixed now! Let me know if it works. Thanks for reporting!

[atawre]

Thanks for quick help. It did work. Here are last few messages from Ninja command -

This is probably a first step for me to look at what OMR is all about.

=> (integer 0)

[youngar]

The branch master currently prints a bunch of debug garbage collection information, which is the majority of what you're seeing. The output Hello world! and the return value of an (integer 0) is the important part, it looks like everything is working!

This is a great way to get started with OMR. Most of the presentation material we have here focuses on using the jitbuilder component of OMR. We are currently in the process of adding true javascript objects b9 using the OMR garbage collector, and the documentation and tutorials will hopefully come concurrently.
