我已经使用C/C++大约7个月了,目前我正在尝试编写一小组线性代数程序.现在我正在尝试测试我的vector类,但是收到错误消息:

在/usr/include/c++/4.2.1/stdexcept:43中包含的文件中,来自vector.cpp:8:/usr/include/c++/4.2.1/exception:40:错误:'#pragma'不允许这里

我正在运行Mac OS X 10.6.5,并检查了我的/usr/include/i386_types.h文件与http://www.opensource.apple.com/source/xnu/xnu-1456.1.26/bsd/i386/_types.h中找到的文件.无论价值多少,它们看起来都是一样的.

以下是我的测试人员文件的内容

#include <cstdlib> // L8: the offending line
