debug - MDK - arm-none-eabi - 从MDK工程做一个makefile工程出来

概述

想从一个基于arm-gcc工具链编译的MDK工程，做一个makefile工程出来。
达到和MDK工程编译一摸一样的效果。

前面做了实验(debug - MDK - arm-none-eabi - 将MDK工程编译过程的所有命令行参数找出来), 已经将MDK工程编译时的全部命令行编译参数找出来了。

现在整理一个makefile出来。

笔记

my_arm_gnu_env_only.bat

先写一个带有arm-gcc环境和gnu-make环境的脚本.

@echo off
rem @file my_arm_gnu_env_only.bat
rem @breif 通用的arm-gcc工具链，编译哪个工程都可以
set path=%~dp0arm-gnu-toolchain\bin;%~dp0gnuwin32\bin;%~dp0curl;%path%
rem set path=C:\nxp\MCUXpressoIDE_25.6.136\ide\;%path%
cmd /k "echo my arm gnu env"

先将编译结果整理成一个bat

为了清晰，先将前面实验找出来的全部命令行参数先要用.bat表达出来，先能干活, 然后再整理成makefile, 这样清晰简单。

build.bat

@echo off
rem @file build.batclsrem 打印bat文件的全路径名称
echo %~f0echo.

运行效果

在cmd中先运行包含arm-gcc环境的脚本my_arm_gnu_env_only.bat，然后再运行build.bat

备注

如果是一个复杂点的工程，可能需要多个.mk才方便编译。
可以用make -c 去到一个子目录中(那里有子模块的.mk), 编译完sub.mk, 再回到主make中。
逐个子模块的.mk都编译完。再执行link.
可以参考开源工程(e.g. Smoothieware)

备注

gnu官方的make手册(https://www.gnu.org/software/make/manual/), 有makefile编写的细节问题，可以去看下。

备注

makefile命令行写的灵活一些，方便扩展到其他工程用，不过也别太过了，毕竟不是经常玩makefile.
makefile优化差不多就行，免得自己以后(e.g. 1年以后?)看时，看不懂就坏了。
