[antlr-interest] ANTLR3 C Target Runtime Error

Hi,
Thanks for your reply.
I have tried one of those examples but I still get the same runtime crash
due to the fact that the state "member" variable is not initialized.
Is there a way to properly initialize it?
( as opposed to just passing it as a parameter which doesn't work).
Thanks!

Download the examples from the download page and check out the driver there, in case there is something else that is no up to date in my online docs (that I will update soon;-)

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.
