[antlr-interest] Linking against the C runtime.

[dario.damico at damix.it]

The same happens when compiling for i386, like in:

    gcc -lantlr3c -arch i386 SimpleCalcParser.c SimpleCalcLexer.c

Then I found the solution proposed by Shinji Nakamatsu in:

    http://www.antlr.org/wiki/display/ANTLR3/Five+minute+introduction+to+ANTLR+3

Sorry, I didn't see that comment before.

Subject : [antlr-interest] Linking against the C runtime.

> Hi everybody, I have a problem linking against the C runtime for ANTLR. I'm using the following software:
> 
>   Operating system: Mac OS X 10.7.4 
>   ANTLRWorks+ANTLR: Version 1.4.3 - for Windows, Linux and Mac OS X
>   ANTLR C Runtime : libantlr3c-3.4.tar.gz
> 
> I installed the runtime like this:
>   ./configure --enable-64bit
>   make
>   sudo make install
> 
> I used ANTLRWorks to generate lexer and parser for a grammar; I obtained
> 2 .c files and 2 .h files. I tried to compile them like this:
> 
>   gcc -lantlr3c SimpleCalcParser.c SimpleCalcLexer.c
> 
> But I got this error:
> 
>   SimpleCalcParser.c: In function ‘main’:

> In these emails, http://www.antlr.org/pipermail/antlr-interest/2010-September/039702.html a problem similar to mine was reported, and was completely solved by adding the --enable-64bit flag.
