mingw32

问题 currently I am trying to make a windows application using c++. For compiling my program I use Mingw GCC. Btw I'm on Windows 10. But as soon as I use int WINAPI wWinMain(HINSTANCE hInstance, HINSTANCE, PWSTR pCmdLine, int nCmdShow) instead of int main() the compiler shows me following message: C:/mingw-w64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/../../../../x86_64-w64-mingw32/lib/../lib/libmingw32.a(lib64_libmingw32_a-crt0_c.o):crt0_c.c:(.text.startup+0x2e): undefined reference to

问题 I have installed GitHub for Windows recently and am using the git bash prompt - the one thing that is bugging me right now is when I type LS all directories are listed in blue. How do I change my git bash shell so that when I type LS the directories are listed in a different color to blue? 回答1: This is not specifically a git issue but more the shell that you are using. On MINGW32 using Git 2.9+: C:\Program Files\Git\etc\ bash.bashrc # Uncomment to use the terminal colours set in DIR_COLORS

问题 I would like to install mingw32 on my Ubuntu (16.10) cuz I would like to generate an x86 windows version of my application. The "i586-mingw32msvc-g++" executable is needed by my Makefile (CMake). I tried "sudo apt install mingw32" but it doesn't work (I have a "package not found" error). 回答1: Look more closely at what is actually available: edd@max:~$ apt-cache search mingw- libassuan-mingw-w64-dev - IPC library for the GnuPG components -- Windows port libgcrypt-mingw-w64-dev - LGPL Crypto

问题 I’m working on a project with opencv lib. I use Qt 4.8 on Windows 7 and it gives me an error when building the project: mingw32-make.exe[1]: *** Access is denied. . Stop. mingw32-make.exe: *** [release] Error 2 19:05:06: The process "F:\QtSDK\mingw\bin\mingw32-make.exe" exited with code 2.

问题 I'm trying to compile c++ programs from the commandline, but I can't. I tried all the steps and instructions listed here. I got MinGW installed, but I get stuck in the last step of the installation that explains how to change environment paths. There simply isn't PATH part of it on the environment variables, and when I try to add it or even edit the one in System variables, compiling doesn't work (nothing comes up when I type g++ on the command prompt). I've searched online for solutions, but

问题 I have used OpenCV 3.2.0 since a long time ago. Recently, I need to implement face detection with landmark detection so I decided to build the OpenCV again with extra OpenCV modules. However, it seems that OpenCV 3.2.0 is not compatible with the latest extra OpenCV modules so I have to build it with the latest OpenCV (which is 4.0.0) The problem is, I'm in a Catch 22 situation. 1. If I use mingw 32bit 5.1.0 to build OpenCV (which is a compiler bundled with Qt), I have a following error

问题 I just have a quick question. I've noticed that I don't have stdafx.h in my compiler(mingw32 on windows) Am I supposed to have it? Or maybe is there a way to get around it? Thanks for reading EDIT: ok here is my current build log once I took out ALL of the includes of stdafx.h http://pastebin.com/bczLr8xY 回答1: Read this wikipedia article. The paragraph I linked and the paragraph below it (mingw32 uses GCC). http://en.wikipedia.org/wiki/Precompiled_header#stdafx.h Since stdafx.h contains the

问题 The code removing all of the three buttons on the title-bar and removing the scroll-bar I use in "Windows 7" so far is listed: #define WINVER 0x0501 // WinXP and UP #include <windows.h> int main ( void ) { //Get a console handle HWND ConsoleWindow = GetConsoleWindow(); //Change Settings SetWindowLong (ConsoleWindow, GWL_STYLE, WS_THICKFRAME); SetWindowLong (ConsoleWindow, GWL_STYLE, WS_CAPTION); SetWindowPos (ConsoleWindow, HWND_TOPMOST, 0, 0, 0, 0, SWP_FRAMECHANGED | SWP_SHOWWINDOW); /

问题 I've been attempting to test out GLFW with C++ for quite a while and am having constant linker issues. I am fairly new to C++, although I have experience in Java and C#, working directly with the compiler is fairly new to me. Here's my setup information.
