[antlr-interest] Antlr C target with LibXML

[Ivan Brezina]

Hi,
try to execute the compiler like "gcc -E -P" and check the output.
Or try to compile the output manually.
ANTLR adds a define for each token you declare and these macro definitions
do interfere with some datatype present in libxml headers.

For example if you create your own token called "int" in .g
then the GLexer.h will contain a macro definition

#define int <some number>

When you declare your own token names, you should always use some prefix.

Ivan
PS: did you try to switch the order of headers included?
PS2: <off-topic> on the other hand it is impossible to compile ANTLR headers
with QT, because QT contains macro called "emit" white emit is a name
of the function in antlr headers.
