codeblocks

问题 So I keep getting this error when trying to compile C++ code using CodeBlocks. cannot open output file [filename.exe] permission denied It only started today, and it's sporadic and inconsistent. It usually goes away if I shut CodeBlocks down and restart the project, but not always. Sometimes it even goes away when I just press F9 (build & run) several times. I always check Task Manager, but there are never any .EXEs running with my file's name, or anything related to it. I've also noticed

问题 Look at the code below! You will understand what I want: #include <iostream> #include <windows.h> using namespace std; int main() { system("set plock=24865"); system("echo %plock%"); // I know this will not work.But How to make it work? return 0; } 回答1: Well, as you say, that won't work. What's important to understand is why : The system call spawns a child process to run the shell, and then you're setting an environment variable in that child process , which promptly terminates. So perhaps

问题 I'm just starting up with code::blocks using 13.12 and am attempting the simple "Hello, World" WxSmith tutorial at wiki.codeblocks.org, but I can't get the resource compiler to complete without errors. I've not made hardly any changes to what the new project wizard created for me. Here's the build log: windres.exe -I"C:\WxWidgets 3.0.0\include" -I"C:\WxWidgets 3.0.0\lib\gcc_dll\mswud" -J rc -O coff -i C:\Users\John\DOCUME~1\CODEBL~1\TUTORI~1\resource.rc -o obj\Debug\resource.res gcc: error: 3

问题 I'm sorry if this is a duplicate question but I've looked through StackOverflow and Google and haven't come up with an answer yet. I'm using Code::Blocks and SDL and trying to get GLEW working with openGL. The program code is: #include <Windows.h> #include <SDL.h> #define GLEW_STATIC #include <glew.h> int main(int argc, char *argv[]) { //initialize SDL SDL_Init(SDL_INIT_VIDEO); SDL_GL_SetAttribute(SDL_GL_CONTEXT_PROFILE_MASK, SDL_GL_CONTEXT_PROFILE_CORE); SDL_GL_SetAttribute(SDL_GL_CONTEXT

问题 I am using wxSmith in Code::Blocks for a GUI application. Everything is alright for creating basic wxWidgets components but I need to plot something within. Thus, I have downloaded MathPlot, and copied both mathplot.h and mathplot.cpp to my project folder. There is this category 'mathplot' at the wxSmith's palette (at the bottom of the editor). I have selected the 'mpWindow' component, and added #include "mathplot.h" to my main.h file for parameters declaration etc. My problem here is I am

问题 I was trying to use this library to output text on a OpenGL application so far I got a prcompiled library so it would be easier to me to get started so this the code: #include <SDL/SDL_opengl.h> #include <FTGL/ftgl.h> ... ... int main( int argc, char* args[] ) { ... ... //Y U NO WORK! FTGLPixmapFont font("ariblk.ttf"); if(font.Error()) ... ... SDL_Quit(); return 0; } So if I do compile it with this linkers: -lmingw32 -lSDLmain -lSDL -lopengl32 -lglu32 -lSDL_image -lm -lgdi32 -lsdl_mixer -lSDL

问题 I'm trying to create a window which is splitted into 2, 3, 4 etcc different resizable views in mainwindow and I'd like to implement that with wxWidgets in C::B. Actually th canvas itself splits the windows in the requested numbers, but it doesn't place any sash alongn the border of views so that it's very diffciult to notice which view starts where and ends where. I create everything on run time and I was planing to place the sash, or panels around borders of views and hoping to work in my

问题 I have downloaded and installed binaries of wxWidgets and Codeblocks onto my PC with Windows 10. Codeblocks builds and runs HelloWorld. With Codeblocks I then open an existing DEV-C++ project which uses wxWidgets - Codeblocks compiles this with no problems, but the linker fails with a message that a library dll file of Widgets is an "unrecognized format". have spent several hours looking for help on this forum and on the widgets site. I have read about Export Libraries which bridge the gap

问题 thanks in advance for taking a look at this. I'm getting a Windows error message when I try to run this program I wrote in C in Code::Blocks. The funny thing is it compiles fine, and if I lower the upper bound of what I'm testing the program runs fine as well. Details: When I try to run the program, first I get a Windows popup that says "X.exe has stopped working. Windows is checking for a solution to the problem". Shortly this changes to "X.exe has stopped working. A problem caused the
