源代码在linux下写的,先要在windows下编译,用到这几个函数,网上搜到替换(drand48()->((double)rand()/(RAND_MAX+1.0)), srand48->srand, lrand48->rand)
Visual C++ 2008 Standard:M_PI is not definedIn my app I use the constant M_PI.As recommended, in my cpp file I wrote:#define _USE_MATH_DEFINES#include <cmath> The compiler complains: "error C2065: 'M_PI' : undeclared identifier"I have transferred the solution and source files from the Visual Studio 2005 Standard. In this version of VS all was compiled and linked just fine.Replacing the <cmath> with <math.h>#define _USE_MATH_DEFINES#include <math.h>solves the problem: all compiles OK.Also if I define _USE_MATH_DEFINES in ProjectProperties/C++/Prepocessorand #include <cmath> in the cpp module, all works.VS 2010: How to change VC++ directories Inherited values (read only)VS2010 introduces the user settings file (Microsoft.cpp.<Platform>.users.props) to control global settings including Global search path. These files are located at $(USERPROFILE)\appdata\local\microsoft\msbuild\v4.0 directory.The issue you are seeing is a bug in the UI. To make it possible to change the ordering of these read-only directories, here is the workaround that you can apply:1. open up the property manager, 2. right click on the .user.props file to bring up the property page3. open up VC++ Directories -> Include Directories, add new paths after $(IncludePath)4. Click on the "Edit" dropdown on VC++ Directories -> Include Directories property, the user directories as well as the inherited values will show up in the upper pane5. you can move the directory orders as you wish and save.
