我尝试在Ubuntu 10.04上使用kdevelop 3.5.4编译应用程序,但它失败并出现以下错误:

checking whether make sets $(MAKE)... yes
checking for g++... g++
checking whether the C++ compiler works... no
configure: error: in `/home/nts/wktools4':
configure: error: C++ compiler cannot create executables
See `config.log' for more details.
*** Exited with status: 77 ***

的config.log:

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.65.  Invocation command line was

  $ /home/nts/wktools4/configure …

我想使用kdevelop4进行c ++编程,但是当我尝试运行应用程序时,kdevelop4需要cmake二进制文件!我怎么解决这个问题？

我正在使用QT Creator调试器.当我尝试调试一个大型数组(即1000,000个元素)时,它会尝试检索整个数组的值,但我只想查看前几个元素.在KDevelop中,调试器仅显示前5个元素,然后按下单击以显示另外5个元素,依此类推.

是否有可能在QT Creator中做同样的事情？

有没有办法强制 KDevelop 对所有变量仅使用单一颜色？

我是 C++ 初学者。我写了以下内容：

// GradeBook.h
#include <iostream>
#include <string> 
using namespace std;

class GradeBook { 
public:
    GradeBook(string); // constructor that initializes courseName
    void setCourseName(string); // function that sets the course name
    string getCourseName(); // function that gets the course name
    void displayMessage(); // function that displays a welcome message 
private:
    string courseName; // course name for this GradeBook
};

// GradeBook.cpp
#include <iostream>
#include "GradeBook.h"
using namespace std;

GradeBook::GradeBook(string name)
{
    setCourseName(name);
} 

void GradeBook::setCourseName(string name)
{
    courseName = name; …

我正在编写我的第一个大c ++项目,但在运行程序时遇到了分段错误.我已经尝试使用valgrind调试它,但到目前为止还没有成功.由于程序非常大,我只会显示发生错误的相关函数:

void RigidBody::RotateAroundAxis(   dReal Angle,
                                    dRealVector3 Axis,
                                    dRealVector3 Anchor)
{   
    std::cout<<"RotateAroundAxis BodyID: " << this->GetBodyId()<<std::endl;
    dRealMatrix3 RotationMatrix=HelperFunctions::RotateAroundAxis(Angle, Axis);
    dRealMatrix3 CurrentRotation=this->GetRotation();
    dRealVector3 Position=this->GetPosition();
    dRealMatrix3 newRotationMatrix=boost::numeric::ublas::prod(RotationMatrix,CurrentRotation);
    std::cout<<"RotateAroundAxis (Debug0) BodyID: " << this->GetBodyId()<<std::endl;    
    SetRotation(newRotationMatrix);
    std::cout<<"RotateAroundAxis Debug"<<std::endl;// This is the last line that is processed without an error.
    std::cout<<"RotateAroundAxis (Debug1) BodyID: " << this->GetBodyId()<<std::endl; // This line probably causes the error.
    //  object is now rotated but needs to be translated
    boost::numeric::ublas::bounded_vector<dReal,3> PosRelToAnchor;
    std::cout<<"RotateAroundAxis (Debug2) BodyID: " << this->GetBodyId()<<std::endl;
    for(unsigned int i=0;i<3;i++){PosRelToAnchor[i]=Position[i]-Anchor[i];};
    PosRelToAnchor=boost::numeric::ublas::prod(RotationMatrix,PosRelToAnchor); …
