codeblocks

问题 Is there a way to set some predefined Macros for my local installation of Code::Blocks. To elaborate on that, basically I would like to have certain blocks compiled only at pc and not anyplace I send the code to. One way to achieve this is as follows: #define MYPC #ifdef MYPC //do something #else // do something else #endif I was to achieve the same thing, but I don't want to include the line #define MYPC and woud like to add this somewhere in the IDE. I know how to do this in Visual Studio,

问题 How to run any exe file from turbo c++? I know that I should stop using turbo c++ and move one to Dev or Code::Blocks, but my school doesn't agree so I gotta wing it. I just want to know how to run a file with or without the system() function. Any kind of advice is welcome Here's what I have tried so far: 1 #include<process.h> int main() { system("tnfsv13.exe"); //tnfsv being a 16-bit application(The need for slowness v 13) return 0; } 2 #include<process.h> int main() { system("tnfsv13.bat");

问题 Installing OpenCV2.4.1 on windows 7 x64 - Mingw & codeblocks Hi, I followed this tutorial Getting started with OpenCV 2.4 and MinGW on Windows 7 I configured the same except instead of x86, i put x64. This is the example #include "opencv2/highgui/highgui.hpp" #include <iostream> using namespace cv; using namespace std; int main(int argc, char** argv) { Mat im = imread(argc == 2 ? argv[1] : "lena.jpg", 1); if (im.empty()) { cout << "Cannot open image!" << endl; return -1; } imshow("image", im)

问题 I installed OpenCV 2.4.0 in codeblocks IDE with help of this link in my windows 32bit pc. I follow the all the steps properly I think. when I run the following code it works well: #include "opencv2/highgui/highgui.hpp" #include <iostream> using namespace cv; using namespace std; int main() { cout<<"Hello"<<endl; return 0; } But when i run this code it shows that The application was unable to start correctly (0xc00000be) #include "opencv2/highgui/highgui.hpp" #include <iostream> using

问题 How to put a c++ variable data into system() function? Look at the code below: #include <iostream> #include <windows.h> using namespace std; int main() { cout << "name the app u want to open"; string app; cin >> app; system("start app"); // I know this will not work! But how to make it will? return 0; } 回答1: Simply concatenate the "start" prefix and app variable, and pass the result to system() as a c-style string, like this: #include <iostream> #include <windows.h> using namespace std; int

问题 So I've been trying to teach myself to use VBOs, in order to boost the performance of my OpenGL project and learn more advanced stuff than fixed-function rendering. But I haven't found much in the way of a decent tutorial; the best ones I've found so far are Songho's tutorials and the stuff at OpenGL.org, but I seem to be missing some kind of background knowledge to fully understand what's going on, though I can't tell exactly what it is I'm not getting, save the usage of a few parameters.

问题 OK, so I downloaded Codeblocks and I already have a cygwin terminal on my computer that I regularly use to compile and run C programs, but when I try to build a program in CodeBlocks, it gives me an error: The compiler's setup (GNU GCC Compiler) is invalid, so Code::Blocks cannot find/run the compiler. I don't know why it can't find my compiler or why it's looking for GNU GCC compiler when I have Cygwin GCC as the default compiler. 回答1: I faced the same problem. I have fixed out by going to
