scons Windows 平台编译报错（文件路径太长）规避办法

10

# 报错内容： arm-none-eabi-g++: fatal error: cannot execute'c:/programfiles/env-windows-v1.3.2/tools/gnu_gcc/armgcc/mingw/bin/../lib/gcc/arm-none-eabi/10.3.1/collect2.exe: CreateProcess: No such file or directory  # 原因： 链接时参数（.o文件集合）长度超过windows限制的最大长度。CreateProcess WINAPI[函数](https://www.jb51.cc/tag/hanshu/)，它接受参数的最大长度是32767个字符。因为代码保存的路径比较深，编译的文件又比较多，导致在链接的时候长度超过了32767  # 解决办法 - 缩短文件路径 - 分模块编译 第一种，比较简单的做法就是给代码库换个存储位置，但这样做不太优雅，而且别人也很容易再遇到相同问题。所以我使用了另一种方式，把编译生成的.o文件统一放到一个文件夹下面来缩短路径。这个方式需要更改的地方并不多，具体如下：  通过下图可以看出，编译时的路径，明显缩短了很多，而且不再受代码库存储位置的影响。当然这种方式如果文件很多，还是会出现问题，目前对于我的应用（编译二三百个文件）来说是够了。如果这个方法不能满足您的需求，那有可能得用第二种方法了。  很抱歉，第二种方法我还没搞明白该怎么弄，，，
