After git cloning the repo, the vanilla Makefile does not work for me.

I had to make a few changes:

boost_inc_path = -I/my_path_to_boost/include
boost_lib_path = -L/my_path_to_boost/lib
# global variables
export BISON_EXE = bison
export FLEX_EXE = flex
export CXX = g++

export CXXFLAGS = -Wall -g ${boost_inc_path} -D _GLIBCXX_USE_CXX11_ABI=0
export LINKFLAGS = ${boost_lib_path} -lboost_program_options -lboost_filesystem -lboost_system

The pre-processor define -D _GLIBCXX_USE_CXX11_ABI=0 was a key missing piece that took me a while to debug, after getting linker issues. The reason we need this define is that the Boost libraries were compiled with this macro OFF, however the Boost headers have this macro ON by default.

Hopefully this helps any future users of this tool.

And thank you Song for creating this brilliant tool. I've been having several issues with the perl library and this one solves all of them.

It seems not support the for loop expansion.
Is my usage incorrect, or is it really not supported?

like this:
<% for( $i = 0; $i < 4; $i += 1) { %>

May I ask for your help？thks~~~
