codeblocks

问题 I'm new to programming so I feel there is something simple I'm missing here. I'm using the latest version of Mac and I've just installed Code::Blocks along with Xcode so I can use the gcc compiler. I created a new "console application" project and the code for a hello world program shows up. I built this code and it gave me 0 errors and 0 warnings so I thought it was off to a good start. But when I go to run this code all I get is the following in my Terminal window: */Applications/CodeBlocks

问题 The delay function of dos.h header file does not work in codeblocks. It shows that delay function is undeclared. the following link contains the program below. link int main () { printf ( " This c program will exit in 10 seconds.\n"); delay(10000); return 0; } 回答1: I was also having same problem & I used this function #include <time.h> void delay(int milliseconds) { long pause; clock_t now,then; pause = milliseconds*(CLOCKS_PER_SEC/1000); now = then = clock(); while( (now-then) < pause ) now

问题 After downloading and installing Code::Blocks with MinGW , I just started a new console project on it and it created a main.c file with this content: #include <stdio.h> #include <stdlib.h> int main() { printf("Hello world!\n"); return 0; } And it does compile. However, when I run it, no "Hello world!" is shown in the console and there is a message like Process terminated with status 1993077897 (0 minutes, 3 seconds) or Process terminated with status -1073741510 (0 minutes, 7 seconds) in the

问题 I try to use wxSound to play sound, but when I try to compile and linking all project. I have this error: C:\wxWidgets-3.0.2\build\msw/../../include/wx/msw/winundef.h:171: undefined reference to `PlaySoundW@12' I Google it and got the answer about adding option -lwinmm to the linker. But it doesn't help 回答1: What are you compiling and linking exactly? Have you tried building the sound sample that comes with wxWidgets? This function is definitely in winmm.lib and wxWidgets makefiles already

问题 How can I increase the stack size in Code::Blocks? I've read this and it says default stack size in VS is 1MB. Now as far as I am concerned, it has nothing to do with VS and stack size is OS dependent. In my win10 case it is 1MB. This seems a little bit outdated as following this: project->build options->linker settings->other linker options doesn't exist no more. There's no build under project bar. Anyway, I need to increase my stack size so I can declare a huge two dimensional char array

问题 I'm learning C++ with Code::Blocks, and everytime i try to create a new class, I get an error message saying: undefined reference to `WinMain@16' Here's the code I've been using: Main Class #include "Lime.h" #include <iostream> using namespace std; int main() { Lime lime; return 0; } Lime Class (.ccp): #include "Lime.h" #include <iostream> using namespace std; Lime::Lime() { cout<<"Hi!"; } Lime Header (.h): #ifndef LIME_H #define LIME_H class Lime { public: Lime(); }; #endif If someone knows,

问题 I am trying to run the following code, but I am getting the following error. error: cannot declare pointer to 'int&' #include <iostream> using namespace std; int main() { int x = 5; int *ptr = &x; int &(*y) = ptr; *y = 5; cout << *ptr << endl; return 0; } 回答1: If you just want a new pointer to the same region of memory, use: int *y = ptr; This not so much an "alias" in that if you change *ptr or *y , both will change, but if you change the pointers themselves, the other will not be updated.

问题 I wanted opengl for code::blocks and used the link below to set it up: http://www.deannicholls.co.uk/tutorials/show/cpp_glut I tried the example file: #include <iostream> #include <GL/glut.h> using namespace std; GLfloat mat_ambient[] = {0.5, 0.5, 0.5, 1.0}; GLfloat mat_specular[] = {1.0, 1.0, 1.0, 1.0}; GLfloat mat_shininess[] = {50.0}; GLfloat light_position[] = {10.0, 10.0, 10.0, 0.0}; GLfloat model_ambient[] = {1.0, 0.5, 0.5, 1.0}; void setupMaterials() { glMaterialfv(GL_FRONT, GL_AMBIENT
