为什么不是命令“cmake".生成makefile?

问题描述

我在终端中运行 cmake . 并说它生成了一些东西，然后我运行 make 并说

I run cmake . in terminal and it says it generated something, then I run make and it says

make: *** No targets specified and no makefile found.  Stop.

我想我错过了一些我需要做的事情，但我不知道是什么.它应该创建了一个 make 文件，然后我可以构建并安装该文件.

I'm guessing I've missed something else that I need to do but I can't figure out what. It should have created a make file that I can then build and then install.

如果我说的太含糊了，请告诉我我还能对这个问题补充什么.

If I'm being too vague please let me know what more I can add to this question.

$ cmake .

推荐答案

似乎 CMake 默认在 Mac 上生成 XCode 项目.CMake 生成 freeglut.xcodeproj 以及所有支持文件.

It seems CMake defaults to generating an XCode project on Mac. CMake generated freeglut.xcodeproj along with all supporting files.

你最好从一个空目录运行 cmake，这样你就可以看到它在运行时实际做了什么.

You are better off running cmake from an empty directory, so you can see what it actually does when it is run.

要生成 makefile(并创建构建目录)，请执行

To generate a makefile (and create a build directory), do

mkdir -p cmake-build && cd cmake-build
cmake .. -G"Unix Makefiles"

然后它应该生成一个Makefile.
