推荐答案

如果它是一个简单的单一源程序:

If it is a simple single source program:

make foo

其中源文件是foo.c或foo.cpp等.

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

您甚至不需要makefile. Make具有足够的内置规则，可将您的源文件构建为具有相同名称(减去扩展名)的可执行文件.

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-但是您将最需要指定可执行文件的路径，因为外壳程序将仅搜索$PATH中的内容以查找可执行文件，并且大多数情况下会执行此操作.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 (.).

因此要运行构建的可执行文件foo:

So to run the built executable foo:

./foo
