[antlr-interest] ANTLR3 C Target Runtime Error

[H S]

The code I am using is the one in the documentation found here:
http://www.antlr.org/api/C/index.html

I have just changed these two lines, just to make it compile:

tstream = antlr3CommonTokenStreamSourceNew(ANTLR3_SIZE_HINT, lxr->pLexer->tokSource);

if (psr->pParser->rec->errorCount > 0)

For the first one, I had added the TOKENSOURCE macro and for the second one I changed errorCount to getNumberOfSyntaxErrors.

That's really it.

Thanks,
Hai

Correct function, but obviously you are doing something wrong because the hundreds of parsers out there already would not be there if there was a bug as fundamental as this one. Follow the C examples or post your driver code so we can see what you are doing wrong.
