[antlr-interest] Need help getting the Antlr C runtime to link into test app.

[Jim Idle]

You do not need to flag it as extern C, that is already done. Other than that, there is not enough information here, such as your .g file, the command lines you are using and so on.

It does work, but you should base your driver program around the C examples.
