我的MacBook上默认使用GNU 4.7.1。当我在学校的服务器上运行我的程序时，我不断收到大量的段错误。我从学校服务器下载了程序的当前状态，以便我可以使用NetBeans来帮助调试。我遇到了很多问题，让新的GNU取代我的MacBook继续设置为默认版本的古老版本。
OSX编译器对我来说是全新的，我无法调整我的makefile以编译它在我学校服务器上的所有内容。
人们告诉我使用gcc或g ++代替另一种，但是其他人告诉我它应该没关系。根据我的理解，OSX使用不同的库来为新版本的GNU for c / c ++，现在Clang是标准的？我想坚持使用GNU / GCC，因为这是我在CS课程中使用的。
目前看来，当我的makefile尝试链接“std :: mt19937”时，它找不到链接它的标题。
我的问题是：如何编译我的makefile以便使用std :: mt19937和c ++ 11库？
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
我尝试将-std = c ++ 11和-std = gnu ++ 11换成“-std = c ++ 0x”。我也尝试过添加它们。我也尝试用g ++交换gcc，但我似乎尝试或改变的所有内容都会导致更多的错误和警告。
这是当前错误消息的第一部分（它继续，然后打开）：

答案 0 :(得分：0)
原来我搞砸了我的编译器和安装到错误位置的MacPorts的路径？新的OSX安装和适当的GNU undated解决了它。
