问题 When I am running below code in Code::Blocks in Windows OS. I used to get an error called undefined reference to fork(). I did set/choose GCC compiler as my default compiler. #include<stdio.h> #include<unistd.h> void main() { int x; x = 0; fork(); x = 1; ... .... } Please help me and tell me, can I right unix/linux programs in Code::Blocks in windows environment? And I write another program, main() { int x = 0; if(x == 0) { printf("X = %d", x); sleep(1000);//used delay also x = 1; printf("Now

问题 I recently realized that I am not even in C99 mode after receiving the compile error 'for' loop initial declarations are only allowed in C99 mode I found some advice on how to get to C99 via a quick search which has told me to go to Projects -> Properties... But alas, it is greyed out and I am not sure that is even the correct way to fix it (probably not available because my file is not a project, it is a normal source file). I have also seen a lot of similar questions saying to enable C99

问题 I just recently started learning C++ with Code::Blocks. When I first started using it, the autocomplete worked fine, but now it doesn't for some reason. What I mean by autocomplete is this: #include <iostream> using namespace std; int main(){ int test; } If I were to type "te" (without the quotes), I wouldn't get a box that has the name of my variable in it. Any help would be appreciated. 回答1: Disabling SmartSense (settings/editor/code completion) can resolve the problem. With SmartSense

问题 I am trying to setup MingW and Code::Blocks on my Windows 8 64 bit laptop, and I'm facing some problem while building a main.cpp file. These are the versions that I have installed: x86_64-w64-mingw32-gcc-4.7.4-release-win64_rubenvb.7z for MingW (4th one in that list), and codeblocks-12.11-setup.exe for Code::Blocks . I've set the path to mingw64\bin in the environment variable. Also, in the Code::Blocks compiler settings, I have set path for all ToolChain Executables . There are two gcc in

问题 I'm following this guide to install Boost on Windows XP running CodeBlocks: http://wiki.codeblocks.org/index.php?title=BoostWindowsQuickRef. I have downloaded Boost and BoostJam and the versions are Boost: 1.52.0 BoostJam: 3.1.18.1-ntx86 I am trying to build Boost (the section "Build Boost" in the guide), so I have set the PATH succesfully to c:\boost-jam Now I want to run boost-jam, and I write: bjam --toolset=gcc "--prefix=c:\program files\codeblocks" install This is where I get an error.

问题 Hello I'm writing a c++ program and I need to get what's on clipboard into a string variable. I found a lot of solutions but all of them were written for windows. Is there any method without using the QT libraries? I found something related to X11 but not very explicit aswell. Thank you very much 回答1: Did you try to find not a code first but a program with an implementation ? I did it for you and found a lot of implementations which use direct X11 calls. I think the most valuable is this but

问题 I'm trying to set up my Code::Blocks work environment on a new computer and I'm having some problems. It's been a long time since I first did this, and now when I open my major project Boost is causing me problems. I'm fairly new to C++ still and fixing this type of problem is something I have limited experience with. When I open my project and try to compile it, I get this error: fatal error: boost/algorithm/string.hpp: No such file or directory| At this part of one of my header files:

问题 When debugging a program in Code::blocks, how do you specify command line arguments to be sent to the program being debugged. I can't find where to set this for the life of me and google searches bring up settings for debugging the compiler itself, rather than programs written in the compiler. It would be a strange thing to leave out. Thanks, Tim. 回答1: Ah, looking with a visual studio head on. It's not in the project settings dialog but off the project menu: Project->Set Programs Arguments 来源

问题 How do you add Lapack libraries to Code::Blocks IDE on Windows ?. The files I have are these: ( Victor's Compiled binary libraries for Window s on this page: http://www.stanford.edu/~vkl/code/libs.html ) lapack_win32.a lapack_win32.def lapack_win32.dll lapack_win32.exp lapack_win32.lib How would look like a simple example in C/C++ using the dynamic library? Do I use #include <lapack> ? or how? 回答1: First assuming you have installed these libraries in C:\LapackLib. Click on the Settings Menu

问题 I want to debug my c++ code using code::blocks. I open a new project and paste my code. But there is above error. To be honest, I'm not sure what is my compiler! when I want to run my code, I write: g++ -std=gnu++11 mycodename.cpp in the terminal. How can I remove above error in Linux? A step by step answer is highly appreciated. I change the compiler from setting...compiler to gnu gcc but the error is about intel compiler! 回答1: I want to debug my c++ code using code::blocks. Don't, because
