关于条件编译的问题
初学c++,在vc++里想用一下流行的那个matrix tcl ,可毫无头绪啊,老报重定义,想看懂下面的代码需要什么知识啊?
#ifndef _NO_NAMESPACE
using namespace std;
using namespace math;
#define STD std
#else
#define STD
#endif
#if !defined(_NO_TEMPLATE)
# if defined(_MSC_VER)
# if _MSC_VER > 1000
# include <complex>
typedef complex<double> type;
# else
typedef double type;
# endif
# elif defined(__BORLANDC__)
# if defined(__WIN32__)
# include <complex>
typedef complex<double> type;
# else
# include <complex.h>
typedef complex type;
# endif
# elif defined( __GNUG__ )
# include <complex>
typedef complex<double> type;
# elif defined( _SGI_BROKEN_STL )
# include <complex>
typedef std::complex<double> type;
# endif
typedef matrix<type> Matrix;
#else
typedef matrix Matrix;
#endif
#ifndef _NO_EXCEPTION
# define TRYBEGIN() try {
# define CATCHERROR() } catch (const STD::exception& e) { \
cerr << "Error: " << e.what() << endl; }
#else
# define TRYBEGIN()
# define CATCHERROR()
#endif
简直要崩溃了。
用的下面的那个模板

想把这些东西看懂的话,能推荐一些相关材料不?
