Cannot build / run tests?

[vidstige]

Hi,
I would like to add some feature to this awesome project. However, after cloning and running make it gets stuck on this error:

pascal.js vidstige$ make
jison parse.jison
make: jison: No such file or directory
make: *** [parse.js] Error 1

I guess jison needs to be downloaded somehow. I tried npm install to no avail. Doing some research right now to see if I can resolve it.

Ok, fixed the build in #2. I can now run parse.js to get an AST by issuing node parse.js examples/hello.pas. Where do I go from here? Thanks.

@vidstige I updated the README with a bit more information about how to use the code including how to generate JavaScript. The JavaScript output works, however, LLVM/clang IR format has changed since I wrote this (specifically the getelementptr keyword). For example:

$ node compile_native.js tests/ffib.pas build/ffib
.../pascal.js/compile_native.js:17
        throw new Error("Errors during compilation:\n" + stderr);
        ^

Error: Errors during compilation:
llc-3.8: <stdin>:5:72: error: expected comma after getelementptr's type
@BOOLEAN_0_ = global [2 x i8*] [ i8* getelementptr inbounds ([6 x i8]* @BOOLEAN_0_.FALSE_1_, i32 0, i32 0), i8* getelementptr inbounds ([5 x i8]* @BOOLEAN_0_.TRUE_3_, i32 0, i32 0) ]
                                                                       ^

This means that the IR being generated by ir.js is no longer compatible with recent versions of clang/LLVM. I'm not going to have time to debug this myself, but I would be happy to accept a fix if you want to track it down. There may be other problems apart from the getelementptr issue, but for that one I would start here:

• http://lists.llvm.org/pipermail/llvm-dev/2015-October/091019.html
• http://stackoverflow.com/questions/40118694/expected-comma-after-getelementptrs-type-llvm

Oh, and make sure you either have an executable named llc or change the LLC variable in compile_native.js to point to you llc executable. For example, on Ubuntu 16.10 with clang installed, I change the LLC variabled to "llc-3.8".

Worked like a charm, got some fibonacci numbers printed in my terminal here. I'm on mac though, and not so interested in native anyway. Thanks for your quick help. 👍 I will try to see if I can get this to build in travis ci as well.
