在Makefile中使用Clang ++代替G ++

Question

我有一个makefile,使用g ++ 4.6可以很好地构建我的项目.

#specify the compiler  
GXX=g++ -std=c++0x

# Specifiy the target  
all: linkedList

# Specify the object files that the target depends on  
# Also specify the object files needed to create the executable  
linkedList: StudentRecord.o Node.o LinkedList.o  ListMain.o
    $(GXX) StudentRecord.o Node.o LinkedList.o  ListMain.o -o linkedList

# Specify how the object files should be created from source files  
LinkedList.o: LinkedList.cpp
    $(GXX)  -c  LinkedList.cpp

ListMain.o: ListMain.cpp
    $(GXX)  -c  ListMain.cpp

StudentRecord.o: StudentRecord.cpp
    $(GXX)  -c  StudentRecord.cpp

Node.o: Node.cpp
    $(GXX)  -c  Node.cpp

当我将第一行更改为GXX = clang++ -std=c++0xclang时会抛出一些相当密集的错误,关于iostream在此之后没有找到正确的args或其他许多错误(但这是"root"错误).

In file included from /usr/include/c++/4.6/iostream:39:
In file included from /usr/include/c++/4.6/ostream:39:

/usr/include/c++/4.6/type_traits:630:59: error: '_Tp' does not refer to a value
    : public integral_constant<bool, __is_standard_layout(_Tp)>

这是我的makefile的问题,还是这个简单的编译真的有区别吗？

使用clang 2.9.

注意: clang抱怨的是#include <iostream>

如果您使用的是 OS X Lion (10.7) 或 Mountain Lion (10.8)，请使用“c++”(/usr/bin/c++)，而不是直接使用“clang++”。尽管其中一个是另一个的符号链接，但 clang 有一些智能来设置正确的路径和编译器选项，以完成您在使用 C++ 时所期望的更多操作。
