为x86寻找16位c编译器 [英] Looking for 16-bit c compiler for x86

问题描述

我正在将uc / OS-II从DOS移植到x86（实模式）。我需要：

I am working on porting uc/OS-II from DOS to x86 (real mode). I need:

(1) A compiler generate real mode 16-bit x86 assembly
(2) An assembler assemble the generated assembly into object file
(3) A linker link object files and output executable (raw binary, COM, MZ, PE, ELF are fine)
(4) Standard library without invoking DOS service (int 21h), only depend on BIOS service.

我想知道是否有工具链可以做。

I am wondering whether there is any tool-chain could do it.

非常感谢

推荐答案

查看 FreeDOS 项目。他们有开发人员工具，其中包括编译器，汇编程序和链接器。您可能需要修改标准库，以便使用BIOS调用，而不是int 21h。

Check out the FreeDOS project. They have developer tools that include compilers, assemblers, and linkers. You'll probably have to modify the standard library, though, so that it uses BIOS calls rather than int 21h.
