#   ************ PamCut makefile ************
#    
#     Author: Nicola Mori
#   
#    		This makefile will produce a cut library libPamCut.so. In the "Build options"
#       section the various compilation options can be set; they will propagate to the
#       whole project.
#    


# ------------------------------- Build options ----------------------------#
#
# Normally you will not have the necessity to modify what lies below, if you
# correctly specified the names for the submakefiles in include.mk. Modify
# the options below to set optimization flags, compiler name and so on. 
#

# C++ compiler and linker
C++ = g++

# Optimization flags.
# 1) Use -O, -O1, -O2, -O3 to optimize for speed or -g, -g1, -g2, -g3
# for debugging (slower execution).
# 2) Uncomment -DDEBUGPAMCUT to enable debug sections in the .cpp code (these sections must be included between
# "#ifdef DEBUGPAMCUT" and "#endif"). Note that if you
# use debug instructions also in the .h code (headers) you will also have to add -DDEBUGPAMCUT
# to the compiler options for the main analysis program.
OPTIMIZE = -g3 #-DDEBUGPAMCUT


# Library flags
# Pamela software is modular, so some libraries may not be available in some istallations.
# To avoid linking problems, here you can define flags to exclude those parts of the
# PamCut software which make use of unavailable libraries. Remember to place
# the code to be excluded between proper preprocessor directives. See the documentation or the cut
# TofNucleiZCut for an example.

EXCLUSIONFLAGS = -DNO_CALONUCLEI -DNO_TRKNUCLEI #-DNO_TOFNUCLEI -DNO_CALONUCLEI -DNO_TRKNUCLEI

# Put below the files on which every .cpp  must depend on, ie., those files that,
# if modified, will trigger a complete recompilation of the project. 
COMMONDEPS = makefile

# The file include.mk contains the inclusion of all the sub-makefiles (subdir.mk)
# in the project. Includes for new cuts must be added there and not below... 
-include include.mk

#-------------------------------- Make body --------------------------------#
#
# Below the make commands are defined. There are no options to set in this section,
# so it has to be modified only in case of radical changes to the make procedure.

# Remove command for clean
RM := rm -rf

# Additional dependencies from headers of other software (PAMELA, ROOT)
ifneq ($(MAKECMDGOALS),clean)
ifneq ($(strip $(CPP_DEPS)),)
