在我的MacBook中，GNU4.7.1是默认的。当我在学校的服务器上运行我的程序时，我不断地得到大量的分段错误。我从学校服务器下载了程序的当前状态，这样我就可以使用NetBeans来帮助调试。我在让更新的GNU替换我的MacBook继续设置为默认的旧的4.2版本时遇到了很多问题。

OSX编译器对我来说是全新的，我无法调整我的makefile来编译所有的东西，就像它在我学校的服务器上一样。

人们告诉我使用gcc或g++代替其他，但其他人告诉我，这不应该重要。据我所知，OSX为c/c++使用不同的GNU更新版本库，现在Clang是标准吗？我想坚持GNU/GCC，因为这是我在CS课程中使用的。

目前看来，当我的makefile试图链接“std：：‘t 19937”时，它找不到链接它的头。

，我的问题是：如何让我的makefile编译，以便使用std::mt19937和c++11库？

makefile

OBJECTS = Ammunition.o Armor.o Consumable.o Creature.o Entity.o Gold.o Item.o parser.o Potion.o Scroll.o Weapon.o XMLSerializable.o CreatureFactory.o DungeonLevel.o Player.o Tile.o ItemFactory.o
HEADERS = Ammunition.h Armor.h Consumable.h Creature.h Entity.h Gold.h Item.h parser.h Potion.h Scroll.h Weapon.h XMLSerializable.h CreatureFactory.h DungeonLevel.h Player.h Tile.h ItemFactory.h

all: Jhack

# I tried this and adding $(LIBS) where "-std=c++0x" is below.. 
# LIBS = -std=c++0x -std=c++11 -std=gnu++11

%.o: %.cpp $(HEADERS)
    gcc -c $< -o $@ -std=c++0x

Jhack: $(OBJECTS) main.o
    gcc -o Jhack $^

clean:
        rm -f *.o Jhack

run: Jhack
    ./Jhack

我试着把"-std=c++0x“换成-std=c++11和-std=gnu++11，我也尝试把它们都加进去。我也试着用g++交换gcc，但是我似乎想要改变的每一件事都会导致更多的错误和警告。

下面是当前错误消息的第一部分(它不停地进行)：
