# PHP-CPP Makefile
#
# This makefile has a user friendly order: the top part of this file contains
# all variable settings that you may alter to suit your own system, while at
# the bottom you will find instructions for the compiler in which you will
# probably not have to make any changes
#
#
# Php-config utility
#
# PHP comes with a standard utility program called 'php-config'. This program
# can be used to find out in which directories PHP is installed. Inside this
# makefile this utility program is used to find include directories, shared
# libraries and the path to the binary file. If your php-config is not
# installed in the default directory, you can change that here.
#
PHP_CONFIG = php-config
UNAME := $(shell uname)
#
# Installation directory
#
# When you install the PHP-CPP library, it will place a number of C++ *.h
# header files in your system include directory, and a libphpcpp.so shared
# library file in your system libraries directory. Most users set this to
# the regular /usr/include and /usr/lib directories, or /usr/local/include
# and /usr/local/lib. You can of course change it to whatever suits you best
#
# Since OSX 10.10 Yosemite, /usr/include gives problem
# So, let's switch to /usr/local as default instead.
ifeq ($(UNAME), Darwin)
INSTALL_PREFIX = /usr/local
else
INSTALL_PREFIX = /usr
endif
DESTDIR_HEADERS = $(INSTALL_PREFIX)/include
DESTDIR_LIB = $(INSTALL_PREFIX)/lib
#
# SONAME and version
#
# When ABI changes, soname and minor version of the library should be raised.
# Otherwise only release verions changes. (version is MAJOR.MINOR.RELEASE)
#
SONAME = 2
VERSION = 2.0.0
#
# Name of the target library name and config-generator
#
# The PHP-CPP library will be installed on your system as libphpcpp.so.
# This is a brilliant name. If you want to use a different name for it,
# you can change that here.
#
PHP_SHARED_LIBRARY_BASE = libphpcpp.so
PHP_SHARED_LIBRARY_SONAME = $(PHP_SHARED_LIBRARY_BASE).$(SONAME)
PHP_SHARED_LIBRARY = $(PHP_SHARED_LIBRARY_BASE).$(VERSION)
PHP_STATIC_LIBRARY = libphpcpp.a
#
# Compiler
#
# By default, the GNU C++ compiler is used. If you want to use a different
# compiler, you can change that here. You can change this for both the
# compiler (the program that turns the c++ files into object files) and for
# the linker (the program that links all object files into a single .so
# library file. By default, g++ (the GNU C++ compiler) is used for both.
#
#
# Compiler flags
#
# This variable holds the flags that are passed to the compiler. By default,
# we include the -O2 flag. This flag tells the compiler to optimize the code,
# but it makes debugging more difficult. So if you're debugging your application,
# you probably want to remove this -O2 flag. At the same time, you can then
# add the -g flag to instruct the compiler to include debug information in
# the library (but this will make the final libphpcpp.so file much bigger, so
# you want to leave that flag out on production servers).
#
CXXFLAGS_EXTRA = -Wall -fvisibility=hidden -fvisibility-inlines-hidden
CPPFLAGS_EXTRA = -std=c++11 -DBUILDING_PHPCPP $(shell $(PHP_CONFIG) --includes)
#
# Linker flags
#
# Just like the compiler, the linker can have flags too. The default flag
# is probably the only one you need.
#
# Are you compiling on OSX? You may have to append the option "-undefined dynamic_lookup"
# to the linker flags
#
LDFLAGS_EXTRA = -shared $(shell $(PHP_CONFIG) --ldflags) -Wl,-soname,libphpcpp.so.$(SONAME)
#
# Command to remove files, copy files, link files and create directories.
#
# I've never encountered a *nix environment in which these commands do not work.
# So you can probably leave this as it is
#
RM = rm -f
CP = cp -f
LN = ln -f -s
MKDIR = mkdir -p
#
# The source files
#
# For this we use a special Makefile function that automatically scans the
# common/ and zend/ directories for all *.cpp files. No changes are
# probably necessary here
#
COMMON_SOURCES = $(wildcard common/*.cpp)
PHP_SOURCES = $(wildcard zend/*.cpp)
HEADERS = $(wildcard include/*.h)
#
# The object files
#
# The intermediate object files are generated by the compiler right before
# the linker turns all these object files into the libphpcpp.so shared
# library. We also use a Makefile function here that takes all source files.
#
