libxml2`s version 2.9.3

[VarolOkan]

Thanks for the feedback.
It compiles on my system just fine. Looking at my linking stage

libtool: link: g++ -Wall -Werror -ansi -pedantic -I/usr/include/libxml2 -g -O2 -o test_app main.o /usr/lib64/libxml2.so -llzma -lz -lm -ldl -L/home/varol/AI/libAIML/js/v8//out/x64.release/obj.target/tools/gyp/ -L/home/varol/AI/libAIML/js/v8//out/x64.release/obj.target/third_party/icu/ ../src/libaiml.a -lpcrecpp -lpthread -lrt -lv8_base -lv8_snapshot -licuuc -licui18n -licudata -lv8_libbase.x64 -L../std_utils/src -lstd_utils -Wl,-rpath -Wl,/usr/lib64 -Wl,-rpath -Wl,/usr/lib64

I see that autotools are linking against /usr/lib64/libxml2.so

can you let me know how you used configure ?
