推荐答案

如果是简单的单源程序:

If it is a simple single source program:

make foo

其中源文件为 foo.c 或 foo.cpp 等

where the source file is foo.c or foo.cpp, etc.

您甚至不需要生成文件.Make 有足够的内置规则将您的源文件构建为同名的可执行文件，但没有扩展名.

You dont even need a makefile. Make has enough built-in rules to build your source file into an executable of the same name, minus extension.

运行刚刚构建的可执行文件与运行任何程序相同 - 但您通常需要指定可执行文件的路径，因为 shell 只会搜索 $PATH 中的内容以查找可执行文件，而且通常不包括当前目录 (.).

Running the executable just built is the same as running any program - but you will most often need to specify the path to the executable as the shell will only search what is in $PATH to find executables, and most often that does not include the current directory (.).

所以要运行构建的可执行文件 foo:

So to run the built executable foo:

./foo
