If you want to use ANTLR C runtime library, you should pay attention that it will be compiled to 32-bit library by default even in 64-bit platform:

# ./configure
......
# make
make  all-am
make[1]: Entering directory '/root/Project/libantlr3c-3.4'
/bin/sh ./libtool  --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I. -Iinclude    -m32  -O2  -Wall -MT antlr3baserecognizer.lo -MD -MP -MF .deps/antlr3baserecognizer.Tpo -c -o antlr3baserecognizer.lo `test -f 'src/antlr3baserecognizer.c' || echo './'`src/antlr3baserecognizer.c

In order to build 64-bit library, you should specify --enable-64bit option during configure stage:

./configure --enable-64bit

Then it will be generated to 64-bit library.
