C如何在非unix上工作？ [英] How does C work on non-unix?
问题描述
我已经编程了一段时间，但我的大部分经验都是在unix上。
C编译器如何处理那些用C语言编写的操作系统？
并且没有libc？
在unix上编译C似乎很容易。代码中的所有内容都可以是机器代码，或链接到C库（通常是libc）或链接到内核的
。在非unix操作系统上是否有libc等价物？

I''ve been programming for a while, but most of my experience is on unix.
How do C compilers work on operating systems that weren''t written in C?
And that have no libc?
Compiling C on unix seems so easy. Everything in the code either goes
right to machine code, or links to a C library (often libc) or links to
the kernel. Are there libc equivalents on non-unix OSes?

C（如这里所讨论的）是一种独立于平台的语言，定义为
国际标准。

C (as discussed here) is a platform-independent language, defined
by an international standard.
See:

Ryan，
在有人说这不在主题之外这个小组，我的谦虚
答案是：
如果你在谈论像嵌入式系统这样的东西 - 通常你会用b / b
编译并为您的特定目标生成机器代码 - 然后在目标操作系统上运行该程序。
内核和库不必用C语言编写使用C t o
编写一个程序 - 虽然它可能不是*标准* C.
你想要编译C程序的目标处理器/操作系统是什么？
那里可能有一个C编译器。
希望有所帮助。

Ryan,
Before someone says this is outside the topic of this group, my humble
answer is:
If you are talking about something like an embedded system- usually you
would use a cross-compiler and generate machine code for your specific
target- then run that program on the OS of your target.
Kernels and libs do not have to be written in C for you to use C to
write a program- although it might not be *standard* C.
What target processor/OS are you looking to compile a C program for?
There might be a C compiler out there.
Hope that helps.

为什么它会有所不同？在所有托管的实现（Unix和
否则）上，OS（或类似的东西）提供了一些基本的
功能。 C库可能是该功能的一部分，或者它可以通过使用该功能单独编写
。
Windows碰巧提供动态库（msvc.dll或类似
那样）实现了C库。 Cygwin做了类似的事情。据我所知，这个
与Unix的基本相同。没有''内置''C库的
系统的编译器通常附带他们的
自己的实现。

Why would it be any different? On all hosted implementations (Unix and
otherwise), the OS (or something similar) provides some basic
functionality. The C library may be part of that functionality, or it
may be written separately by making use of that functionality.
Windows happens to provide a dynamic library (msvc.dll or something like
that) that implements the C library. Cygwin does something similar. This
is basically the same thing Unix does, as far as I know. Compilers for
systems that don''t have a ''built in'' C library usually ship with their
own implementation.
