# Makefile for Linux GNU compiler
#
# Usage:
#   make            - Build all tools. They will be copied into 'bin' directory.
#   make clean      - Clean.
#   make hlcsg      - Build hlcsg.
#   make hlbsp      - Build hlbsp.
#   make hlvis      - Build hlvis.
#   make hlrad      - Build hlrad.
#   make ripent     - Build ripent.
#
# Before running the tools, please make sure the default maximum stack size on your computer
#   is more than 4MB.
#
# When compiling with g++:
#   Flag '-fno-strict-aliasing' is a must.
#   All macro definitions should not be changed, because all code were written and checked under this assumption.
#   The following warnings should be ignored:
#     warning: no newline at end of file
#     warning: '???' may be used uninitialized in this function
#     warning: suggest parentheses around assignment used as truth value
#     warning: passing ‘float’ for argument 1 to ‘void seconds_to_hhmm(unsigned int, unsigned int&, unsigned int&, unsigned int&, unsigned int&)’
#     warning: ignoring #pragma warning
#     warning: comparison between signed and unsigned integer expressions
#     warning: enumeration value ‘???’ not handled in switch
#     warning: unused variable ‘???’
#     warning: converting to ‘int’ from ‘vec_t’
