如何使用其他库编译可视化C ++程序 [英] How to compile visual C++ program with additional libraries

问题描述

我定义了来源&标题 - MathCore.h& MathCore.cpp

MathCore.h如下代码：

  #ifdef MATHCORE_EXPORTS 
   #define MATHCORE_API __declspec（dllexport）
  ＃else 
   #define MATHCORE_API __declspec（dllimport）
  ＃endif 
  
 MATHCORE_API  bool  isPowOf_Two（ unsigned   int  n ）; 
 MATHCORE_API  bool  isFormOf_tpnmo（ unsigned   int  n）; 
 MATHCORE_API  int  isolate_LST（ int  x）; 
 
 
  //  此类从MathCore.dll导出 
  class  MATHCORE_API MathEngine {
  public ：
 MathEngine（< span class =code-keyword> void ）; 
  //   TODO：在此处添加您的方法。 
}; 
 
  extern  MATHCORE_API  int  nMathCore; 
 
 MATHCORE_API  int  fnMathCore（ void ）; 

我从visual studio 2008生成了lib - MathCore.lib和各自的dll-MathCore.dll，然后我在一个不同的文件夹中创建了C ++源文件 - t.cpp在MathCore中定义的函数，为简单起见，我将MathCore.lib和MathCore.dll放在同一个文件夹中。

t.cpp就像这样....

  #pragma comment（lib，MathCore.lib）
   #include  < span class =code-preprocessor> <   iostream   >  
   #include      MathCore.h 
  
 使用  namespace  std; 
 
 MATHCORE_API  bool  isPowOf_Two（ unsigned   int  n）; 
 MATHCORE_API  bool  isFormOf_tpnmo（ unsigned   int  n）; 
 
  int  main（）
 {
 
  while （ 1 ）{
  unsigned   int  x; 
 cin>> x; 
 cout<< isPowOf_Two（x）<<   \ n; 
 cout<< x<<   \ n; 
} 
 system（ 暂停）; 
  return   0 ; 
} 

我的问题是..不使用Visual Studio我想用批处理文件编译t.cpp说 - run.bat

所以我将vcvarsall.bat和vcvars32.bat包含在同一个源文件夹中，我的run.bat命令就像这样....

 @ echo off 
 callvcvarsall.bat
 callvcvars32.bat
 echo off 
 cl / O2 t.cpp / link MathCore.lib 
 @if ERRORLEVEL == 0（
 goto good 
）
 
 @if ERRORLEVEL！= 0（
 goto bad 
）
 
：好
 echoclean compile
 echo％ERRORLEVEL％
 goto end 
 
：bad 
 echo错误或警告
 echo％ERRORLEVEL％
转到结束
 
：结束

当我运行run.bat它创建t.obj没有t.exe我认为它没有链接MathCore.lib，我想知道如何使用其他库编译可视化C ++源代码并包含在命令行我chekc视觉工作室命令行辩论它没有帮助我解决这个问题。



请任何人都知道使用所需的libs文件编译可视化c ++源文件的确切命令行论证。

解决方案

我会用

 CL / O2 t.cpp MathCore.lib 

参见 http://msdn.microsoft.com/en-us/library/610ecb4h （v = vs.100）.aspx [ ^ ]以及 / OUT 选项-us /库/ y0zzbyt4（v = VS.100）的.aspx> http://msdn.microsoft.com/en-us/library/y0zzbyt4（v = VS.100）的.aspx [<一个href =http://msdn.microsoft.com/en-us/library/y0zzbyt4(v=vs.100).aspx\"target =_ blanktitle =New Window> ^ ]。

I defined source & header -"MathCore.h" & "MathCore.cpp"
MathCore.h as below code :

#ifdef MATHCORE_EXPORTS
#define MATHCORE_API __declspec(dllexport)
#else
#define MATHCORE_API __declspec(dllimport)
#endif

MATHCORE_API bool isPowOf_Two(unsigned int n);
MATHCORE_API bool isFormOf_tpnmo(unsigned int n);
MATHCORE_API int isolate_LST( int x);


// This class is exported from the MathCore.dll
class MATHCORE_API MathEngine {
public:
	MathEngine(void);
	// TODO: add your methods here.
};

extern MATHCORE_API int nMathCore;

MATHCORE_API int fnMathCore(void);

and I generated lib - "MathCore.lib" and respective dll-"MathCore.dll" from visual studio 2008,then I created C++ source file-"t.cpp" in a different folder which uses functions defined in MathCore,for simplicity I put MathCore.lib and MathCore.dll within same folder.
t.cpp like this....

#pragma comment(lib, "MathCore.lib")
#include <iostream>
#include "MathCore.h"

using namespace std;

MATHCORE_API bool isPowOf_Two(unsigned int n);
MATHCORE_API bool isFormOf_tpnmo(unsigned int n);

int main()
{

    while(1){
    unsigned int x;
    cin>>x;
    cout<<isPowOf_Two(x)<<"\n";
    cout<<x<<"\n";
    }
    system("Pause");
    return 0;
}

My problem is.. without using Visual Studio I want to compile the t.cpp using batch file say -"run.bat"
so I included "vcvarsall.bat" and "vcvars32.bat" to same source folder,my "run.bat" commands like this ....

@echo off
call "vcvarsall.bat"
call "vcvars32.bat"
echo off
cl /O2 t.cpp /link MathCore.lib
@if ERRORLEVEL == 0 (
   goto good
)

@if ERRORLEVEL != 0 (
   goto bad
)

:good
   echo "clean compile"
   echo %ERRORLEVEL%
   goto end

:bad
   echo "error or warning"
   echo %ERRORLEVEL%
   goto end

:end

when I run "run.bat" it creates "t.obj" without "t.exe" I think it does not link MathCore.lib,I want to know how to compile visual C++ source with additional libraries and includes in commandline I chekc visual studio commandline arguements It not helped me to solve this problem.

Please anyone know exact commandline arguements to compile a visual c++ source file with needed libs files.

解决方案

I would use

CL /O2 t.cpp MathCore.lib

See http://msdn.microsoft.com/en-us/library/610ecb4h(v=vs.100).aspx[^] and also the /OUT option at http://msdn.microsoft.com/en-us/library/y0zzbyt4(v=vs.100).aspx[^].
