为什么不是命令"cmake".生成一个makefile? [英] Why isn't the command "cmake ." generating a makefile?

问题描述

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

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.

我猜我错过了我需要做的其他事情，但我不知道该怎么办.它应该已经创建了一个make文件，我可以先构建然后再安装.

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.

如果我不太清楚，请让我知道我可以为这个问题添加的内容.

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连同所有支持文件一起生成了freeglut.xcodeproj.

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

最好从空目录运行cmake，这样一来，您便可以查看它在运行时的实际作用.

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

要生成一个makefile(并创建一个构建目录)，请执行

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

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

然后它将生成一个Makefile.
