VC编译常见错误--1、Fatal Error C1010unexpected end of file while looking for precompiled header di rective这一般是由于使用了参数/Yu"stdafx.h"，意思是在每个文件中都应该使用#include来包含这个头文件。

一般改正，就是在每个。

CPP文件中包含这个文件就可以。

2、LNK2001on__beginthreadex and__endthreadex这是一个非常常见的链接错误。

原因是由于在VC3。

0以后所有的M FC类都是线程安全的，在MFC类库中使用了Thread Local Stora ge(TLS)提供预处理的数据。

因此如果程序中包含了"stfafx.h"头文件或者使用了，MFC类库中的类就会使用MSVCRTx0.DLL来进行链接。

改正方法如下：On Visual C2.x,5.0,and6.0:Select the Project menu,and then continue Steps2throug h5below.On Visual C4.x:Select the Build menu.Select the Settings...option.Select the C/C++tab.Select Code Generation on the Category list box.Finally,make a selection other than Single-Threaded on th e Use Run Time Library list box.如果使用了"Multithreaded using DLL"方式还要求在预处理符号中加上_AFXDLL符号.还在LIBC。

LIB是C Runtime的静态链接库。

MSVCRTx0.DLL是C Runtime的动态链接库。

如果程序中包含了任何MFC代码,或者编译使用了/MT选项,都要求使用多线程库。

为什么在程序中包含了"StdAfx.h"文件也会出现这个连接错误呢？是由于在"StdAfx.h"中使用了MFC类，并且重载了new等操作符，如果在程序中使用了NEW等就会出现链接错误。

/user2/shuquanying/archives/2006/1327664. shtmlVisual C++Error MessagesVisual C++Error MessagesThis page contains a listing of"difficult to diagnose"error mes sages and possible fixes.I haven't taught a programming clas s that uses Visual C++in several years so this list is probabl y out of date by now.It was valid for Microsoft Visual C++ve rsion6.0service pack3.C1001:INTERNAL COMPILER ERROR(compiler file'msc1.cp p',line1786)Please choose the Technical Support command on the Visual C++Help menu,or open the Technical Support help file for more informationThis error results from leaving off the parentheses immediately following the function name in a function header.To correct t he error simply add()to the end of the function name.C1010:unexpected end of file while looking for precompiled h eader directiveIf your project is an MFC AppWizard created project then this error results from not#including StdAfx.h as the first＃i nclu de statement(before any other＃i ncludes,data declarations, or executable program code).C1083:Cannot open precompiled header file:'Debug/<Project-Name>.pch':No such file or directoryThis error results from a missing file-the compiled version of StdAfx.cpp.Visual C++does a poor job of keeping track of t his file and frequently"forgets"how to build it.This problem o ften occurs after restoring a saved workspace from diskette wi thout the Debug directory.To fix the error select StdAfx.cpp fr om the workspace file list them choose Compile from the Buil d menu.If that doesn't work the go to Project->Settings,sel ect the C/C++tab,and click the radio button labeled Create Precompiled Headers.C2001:newline in constantThis error is usually caused by a string or character constant that is missing its closing'or"symbol.C2065:'<data-member name>':undeclared identifierIf this error occurs in one of your member functions then it is generally the result of forgetting the class scope operator in f ront of the function name in your.cpp file.C2143:syntax error:missing';'before'PCH creation point' Check each of the＃i nclude files to ensure that the closing brace of each class declaration is followed by a semicolon.C2143:syntax error:missing';'before'*'If this error is followed by two C2501errors then the problem is an undeclared class name within a pointer declaration.For example,the declaration:CClass*pObject;will generate the above error message followed by a C2501e rror message for'CClass'and another C2501message for'pO bject'.The problem is that the compiler isn't recognizing CClas s as a valid class/type name.To correct the problem add a＃i nclude of the file containing the declaration of CClass(e.g.,＃i nclude CClass.h)C2447:missing function header(old-style formal list?)This error usually results from a missing{or use of a;inste ad of a{following the parameter list of a function header.C2511:'<function-name>':overloaded member function not fo und in'<class-name>'This error results from a mismatch in the parameter list of a member function declaration(.h file)and definition(.ccp file). Check the forward declaration of the function in the.h file and its definition in the.cpp file and ensure that the number of p arameters and the type of each parameter match exactly.C2512:'<constructor-function-name>':no appropriate default c onstructor availableThis error usually occurs when you implement the constructor function of a derived class and forget to include parameter pa ssing to the base class constructor function.For example ass ume that CDerived is derived from CBase and that the CBase constructor function requires one parameter(e.g.,int A).If yo u define the CDerived constructor function as:CDerived::CDerived(int A,int B){...}the compiler will issue the above error message on the line c ontaining the function header of CDerived::CDerived()because you haven't provided instructions for routing the parameter A to CBase::CBase().Because you didn't provide instructions the compiler assumes that CBase::CBase()requires no arguments and it complains because no version of CBase::CBase()has been defined that accepts zero arguments.If you intended to provide a version of CBase::CBase()that re quires no arguments then the error message indicates that yo u forgot to declare that function in your base class declaration (e.g.,in CBase.h).If CBase::CBase()does require one or more arguments then y ou must correct the problem by including explicit instructions for passing parameters from the derived class constructor funct ion to the base class constructor function.The correction for t he example above is:CDerived::CDerived(int A,int B):CBase(A){...}C2556:'<function-name>':overloaded functions only differ by return typeC2371:'<function-name>':redefinition;different basic types These errors usually result from a mismatch of function type b etween a.h and.cpp file.Check the forward declaration of th e function in the.h file and its definition in the.cpp file and make the function return type identical in both files.C2601:'<function-name>':local function definitions are illegal This error results from defining one function inside the body of another function.It usually means that you omitted one or more}symbols in the function just before the function named in the error message.C2653:'<Class-Name>':is not a class or namespace name This error usually results from not having＃i nclude"StdAfx.h" as the first＃i nclude statement in your class.cpp file.It can also occur if your class definition is in a.h file and you forget to＃i nclude that.h file in another file that refers to the cl ass name.C2661:'<Class-Name>::<Function-Name>':no overloaded func tion takes n parametersThis error indicates a mismatch between the parameters used in a function call(e.g.,from main.cpp)and the declaration of the function.The function call is passing n parameters and t here is no function declaration that uses that number of para meters.LNK1104:Cannot open file nafxcwd.libThis error sometimes occurs when a project uses a class fro m the MFC but the project settings don't explicitly tell the link editor to look in the MFC libraries.Go to Project-->Settings(Build-->Settings in Visual C++4.0).On the General tab check the box that says"Use MFC ina Shared DLL".LNK1168:cannot open Debug\<Project-Name>.exe for writing This error occurs when the link editor attempts to write to a. exe file that is currently in use.The.exe file of an executing program is write protected until the program is terminated.Loo k at the status bar at the bottom of your screen and find theicon representing your executable application.Open the applic ation and exit from it.Then select Build.LNK2001:unresolved external symbol__endthreadexLNK2001:unresolved external symbol__beginthreadexThese errors result from using an MFC object or function with out telling the link editor to search the MFC libraries.Go to Project-->Settings(Build-->Settings in Visual C++4.0).On the General tab check the box that says"Use MFC ina Shared DLL".LNK2001:unresolved external symbol_mainYour project doesn't contain a function called main().The error usually results from forgeting to add main.cpp to the project workspace.<File>.obj:error LNK2001:unresolved external symbol"public: void__thiscall<Class1>::<Function1>(<Type>)"This a generic form of a LNK2001error where<File>.obj can be any object file in your project and<Class1>::<Function1>(< Type>)can be any function in any class.Substitute the specifi c<File>,<Class>,<Function>,and<Type>in your message i nto the instructions below to diagnose and correct the proble m.An LNK2001error means that the link editor is looking for a compiled function and can't find it.The call to the"missing fu nction"is somewhere in<File>.cpp.Unfortunately,double-clicki ng on the error message won't take you to the point in<File. cpp>where the function is called but you can search for it wit h Find or Find In Files.The function the link editor can't find i s a member of<Class>,its name is<Function1>,and its retu rn type is<Type>.There are two common reasons for a LNK2001error:The call in<File>.cpp doesn't match the function prototype in <Class>.h and/or the implementation in<Class>.cpp.The mis match may be in the function name,return type,or number a nd/or type of parameters.Correction strategies include: Check that the function name is spelled the same(case sensi tive)in all three files(File.cpp,Class.h,and Class.cpp). Check that the function is actually declared and defined within <Class>-perhaps you defined it as a member of a different class or perhaps you tried to call the function(in<File>.cpp) using an object or object pointer of a different class.Check that the number and type of parameters in the function implementation(in<Class>.cpp)matches the number and typ e of parameters declared in the function declaration in<Class>.h.Check that the number and type of parameters in the function call(in<File>.cpp)matches the number and type of paramet ers declared in the function header in<Class>.cpp.The function was never declared or was declared but never d efined.To see if either is the case go to the ClassView windo w of the Workspace view.Click the+next to<Class>and fin d<Function>in the list of member functions.If<Function>is NOT in the list then it was never declared or defined-add a declaration to the class declaraion in<Clas s>.h and implement the function in<Class>.cpp.If<Function>is in the list then right click on it and select Go To Definition from the pop-up menu.If you get the error mes sage Cannot find definition(implementation)of this function th en the function was declared but never defined(implemented). Implement the function to<Class>.cpp.LNK2005:<some-long-string-of-mostly-garbage>already defined in<name>.lib(<name>.obj)This error usually results from including a source code file mul tiple times.If you recognize any of the names in the message then it probably results from multiple inclusion of one of your own header files.Check to be sure that you've used#ifndef/#define/#endif properly your header files.If you don't recognize the name then it's probably multiple inclusion of a system file (e.g.,afxwin.h).Make sure that you haven't explicitly included something in main.cpp that is already included in one of your own header files.Also check that you haven't＃i ncluded a .cpp file where you should have＃i ncluded a.h file./5383739_d.html作者：happyparrot出处：[url]/Expert/t opic/4258/4258967.xml?temp=.1825373[/url]1.Linking...nafxcwd.lib(thrdcore.obj):error LNK2001:unresolved extern al symbol__endthreadexnafxcwd.lib(thrdcore.obj):error LNK2001:unresolved extern al symbol__beginthreadexlibcd.lib(crt0.obj):error LNK2001:unresolved external symb ol_mainQ:VC++默认的工程设置是单线程的，而你使用了多线程，所以要修改设置。

C语言常见错误解析

C语言常见错误解析

C语言常见错误解析：1)编译错误和运行错误：1，选择编辑的文件类型不是C语言。

如：文件扩展名不是.cpp, 而是.asp等。

重做。

错误提示：解析：编辑区上方的文件名的扩展名为：.asp是网站文件, 不是正常的.cpp文件。

当然编译菜单为灰色，无法编译。

2，做完一个程序后，没有关闭工作区，继续做下一个程序，编译系统无法确定编译多个主函数中的哪一个。

关闭工作区后，重做（这时，可使用复制粘贴方法）。

错误提示：解析：左边看出，有两个main()函数，原来的是t.cpp（工程名也是t）, 现在的是li.cpp,可以编译，但不能运行。

每次运行的都是原来的程序t.exe.同时，可以看到，编译的主文件名li.cpp，与构件的文件名t.exe不相同。

3，编译系统本身故障。

编译菜单呈灰色，无法编译，按下ctl+alt+del三个键，在任务工作区，强制关闭VC,重新启动。

错误提示：略改正方法：按照正确的流程创建C语言源程序文件。

2)宏定义错误：引发语法错误错误原因：1，位置错误，宏定义错误放入函数内部；应在所有函数的前面。

错误提示：解析：遇到define，标志符出现错误，没有定义。

与函数体的语句定义格式不符。

2，缺少宏定义标志符“#”；错误提示：define pi 3.1415927解析：引起三个错误。

3，宏定义后面多加了分号“；”，误认为是语句；错误提示：语句，定义#define pi 3.1415927; 使用宏定义area=2*pi*banjing*banjing;解析：非法间接使用。

4，宏定义中库函数名错误：如sdtil.h, maths.h等错误提示：解析：不能打开stido.h文件，单引号中标志符’stido.h’错误。

5，宏定义中库函数引用标志错误：应使用一对尖括号或一对双引号<>或”“，不用函数标志圆括号( )错误提示：解析：#include中单引号中左圆括号‘（’使用错误，两函数没有定义。

C语言常见错误分析

C语言常见错误分析

C语言常见错误分析C语言是一门非常强大和灵活的编程语言。

然而，由于人为的错误或者语法错误，程序在编译或者运行的过程中常常会出现错误。

下面是常见的C语言错误以及它们的分析。

1.语法错误：语法错误是最常见的错误类型，也是最容易修复的错误。

它们包括缺少分号、括号不匹配、使用未定义的变量等。

这些错误通常会导致编译器的语法错误提示。

2.类型错误：类型错误是由于变量类型不匹配或者操作符错误而引起的。

例如，使用一个整数变量来存储浮点数值，或者将一个指针赋值给一个非指针类型的变量。

这些错误可能导致错误的计算结果或者报错。

3.逻辑错误：逻辑错误是程序的逻辑结构有误，导致程序无法正确执行。

这种错误通常不能通过编译器检测出来，而需要开发人员通过调试来找到并修复。

例如，程序的循环条件错误导致无限循环，或者条件判断错误导致程序走入错误的分支。

4.数组越界错误：数组越界错误是指访问数组时超出了数组的有效范围。

这种错误通常导致程序崩溃或者产生不可预测的结果。

例如，访问数组元素时使用了一个超过数组长度的下标。

为了避免这种错误，开发人员应该始终确保数组下标在有效范围内。

5.空指针错误：空指针错误是指使用了一个未初始化或者已经释放的指针。

这种错误通常导致程序崩溃或者产生不可预测的结果。

为了避免空指针错误，开发人员应该在使用指针之前初始化，并且在使用完毕后及时释放。

6.内存泄漏：内存泄漏是指程序在分配内存之后没有释放，导致系统中的可用内存越来越少。

如果内存泄漏严重，最终可能会导致程序崩溃或者系统变慢。

为了避免内存泄漏，开发人员应该始终确保在不再需要内存时及时释放。

7.死循环：死循环是指程序中的循环条件永远为真，导致程序陷入无限循环。

这种情况可能导致程序无法继续执行后续代码或者崩溃。

为了避免死循环，开发人员应该在循环中始终更新循环条件。

8.未处理的异常：异常是程序运行过程中可能发生的错误，它可能导致程序崩溃或者产生不可预测的结果。

为了避免未处理的异常，开发人员应该使用异常处理机制来捕获和处理异常。

C语言常见错误分析和程序调试

C语言常见错误分析和程序调试

C语言常见错误分析和程序调试C语言是一种常见的编程语言，在使用的过程中，常常会出现一些错误。

本文将分析C语言常见的错误，以及如何进行程序调试。

1.语法错误：语法错误是最常见的错误类型之一、它通常是由于拼写错误、缺少分号或括号不匹配等简单的错误导致的。

解决方法是仔细检查代码，确保所有括号都是成对且正确使用，并及时修正拼写错误。

2.逻辑错误：逻辑错误是指程序的逻辑错误，即程序没有按照预期的方式执行。

这种错误很难被编译器检测到，需要程序员自己进行调试。

解决方法一是使用printf语句来输出变量的值，以观察程序的执行过程；二是使用调试工具，如GDB，来逐步执行程序并观察变量的值。

3.内存错误：内存错误是指在程序中使用了未分配或已释放的内存。

这种错误通常会导致程序崩溃或产生不可预测的结果。

解决方法是保证正确地使用内存函数，如malloc和free，并养成好的编程习惯，即分配内存时要确保及时释放。

4.数组越界：数组越界是指程序访问了数组范围之外的元素。

这种错误可能会导致程序崩溃或产生不可预测的结果。

解决方法是仔细检查数组的索引，并确保索引的值在合法范围内。

5.变量未初始化：未初始化的变量可能包含随机的垃圾值，从而导致程序的不稳定或不可预测的结果。

解决方法是在使用变量之前，先给变量赋初始值。

6.常量溢出：常量溢出是指常量值超过了其数据类型的范围。

解决方法是使用合适的数据类型，并确保常量值在其范围之内。

7.函数调用错误：函数调用错误可能是函数名拼写错误、函数参数类型不匹配或函数调用位置错误等。

解决方法是仔细检查函数名的拼写，确保函数参数与定义一致，并确保函数调用位置正确。

总之，在编写C语言程序时，应该注意避免语法错误，正确使用内存函数和数组索引，初始化变量，选择合适的数据类型，并仔细检查函数调用。

此外，对于逻辑错误，可以通过打印输出和调试工具来进行程序调试，帮助定位问题并解决错误。
