我如何告诉cmake不要创建控制台窗口？ [英] How do I tell cmake not to create a console window?

问题描述

我可以通过gcc实现此目的：

I can achieve this by gcc :

gcc -mwindows -o simple simple.c

但是只能在cmake中找到：

But only find this in cmake:

add_executable(simple WIN32 simple.c)

但它与<$ c并不完全相同$ c> -mwindows ，

这将要求入口点为 WinMain ，

，而 gcc -mwindows 不需要这个（可以是 main ）。

while gcc -mwindows doesn't require this(can be main).

我应该如何正确执行？

推荐答案

如果使用：

add_executable(simple WIN32 simple.c)

然后必须提供WinMain函数。这就是add_executable的WIN32标志的含义：这意味着您要使其成为Windows程序，并提供WinMain函数。

then you must provide a WinMain function. That's what the WIN32 flag to add_executable means: it means you're going to make it a Windows program, and provide a WinMain function.

我建议这样做如果您确实在编写Windows应用程序。

I would recommend doing it this way if you're really writing a Windows application. It's what makes the most sense and fits most naturally with the underlying OS.

但是，如果您仍要传递gcc的 -mwindows标志，请使用主，然后只需将 -mwindows添加到CMAKE_CXX_FLAGS和/或CMAKE_C_FLAGS值。您可以在cmake-gui程序中通过交互式调整这些变量以使其包含 -mwindows来做到这一点，也可以使用CMake命令行来做到这一点，例如：

However, if you still want to pass gcc the "-mwindows" flag, but use a "main" anyway, then simply add "-mwindows" to the CMAKE_CXX_FLAGS and/or CMAKE_C_FLAGS value. You can do this in the cmake-gui program by adjusting those variables interactively to include "-mwindows" or you can do it with command line CMake, like this:

cmake -DCMAKE_C_FLAGS="-mwindows"
