using ./src/luajit-x -bl tests/test-1.lua gives => invalid header #21

./lang/bcread.lua:717: invalid header

This is running on Ubuntu Linux with a luajit 2.1 installed.

Pretty much the same error when running with just luajit instead of luanit-x

Hi,

the language toolkit supports only LuaJIT 2.0 bytecode. The bytecode's header contains the information about the LuaJIT bytecode's version and bcread immediately give up when it does encounter the 2.1 version tag.

Normally implementing support for 2.1 bytecode require some works.

Wiladams commented 9 years ago

OK. So, what you're saying is if I just use 2.0, it should work right?

I hope you do upgrade to 2.1, as there have been quite a lot of bug fixes and performance improvements.

Yes, with 2.0 everything should work fine. The language toolkit has a quite large test suite that cover almost every aspect.

As for 2.1 I note that you are interested. I think also that it is interesting to have but for the moment I don't have a lot of spare time to work on that but in the future I'm probably going to do it.

Ok. For what I am doing, 2.0 is ok.

Using luajit 2.0 works fine, thanks.

Are there any grammars for 'C' or other languages besides Lua as yet?

Short answer: no. :-)

I would love to have another grammar to show an example of the usage of the parser but nothing other than Lua is available right now.
