How do I build my parser in C++?
In general, you need to compile all the supplied .cpp files (in the cpp directory), and link them to your project. I recommend building a library.
I use the GNU compiler, g++, on Linux as follows:
g++ -I. -c *.cpp
ar r libantlr.a *.o
Or, to build a shared library:
g++ -fPIC -I. -c *.cpp
g++ -shared -Wl,-soname,libantlr.so -o libantlr.so *.o
g++ -I .../antlr/cpp -c *.cpp g++ -o app_name *.o -L .../antlr/cpp -l antlr
On Windows, with MSVC, I build a static library (antlr.lib) from the supplied .cpp files as one project, and link it into subsequent projects which use ANTLR. I believe others have built DLLs of ANTLR, but I haven't tried it.
