# A sample Makefile for building Google Test and using it in user

# tests.  Please tweak it to suit your environment and project.  You

# may want to move it to your project's root directory.

#

# SYNOPSIS:

#

#   make [all]  - makes everything.

#   make TARGET - makes the given target.

#   make clean  - removes all files generated by make.

# Please tweak the following variable definitions as needed by your

# project, except GTEST_HEADERS, which you can use in your own targets

# but shouldn't modify.

# Points to the root of Google Test, relative to where this file is.

# Remember to tweak this if you move this file.

GTEST_DIR = ..

# Where to find user code.

USER_DIR = ../samples

# Flags passed to the preprocessor.

# Set Google Test's header directory as a system directory, such that

# the compiler doesn't generate warnings in Google Test headers.

CPPFLAGS += -isystem $(GTEST_DIR)/include

# Flags passed to the C++ compiler.

CXXFLAGS += -g -Wall -Wextra -pthread

# All tests produced by this Makefile.  Remember to add new tests you

# created to the list.

TESTS = sample1_unittest

# All Google Test headers.  Usually you shouldn't change this

# definition.

GTEST_HEADERS = $(GTEST_DIR)/include/gtest/*.h \

                $(GTEST_DIR)/include/gtest/internal/*.h

# House-keeping build targets.

all : $(TESTS)

clean :

	rm -f $(TESTS) gtest.a gtest_main.a *.o

# Builds gtest.a and gtest_main.a.

# Usually you shouldn't tweak such internal variables, indicated by a

# trailing _.

GTEST_SRCS_ = $(GTEST_DIR)/src/*.cc $(GTEST_DIR)/src/*.h $(GTEST_HEADERS)

# For simplicity and to avoid depending on Google Test's

# implementation details, the dependencies specified below are

# conservative and not optimized.  This is fine as Google Test

# compiles fast and for ordinary users its source rarely changes.
