Question

我将Platformio与ESP8266，WiFi板，4M RAM，32位处理器一起使用。

一个网站被嵌入：一个页面，用xxd编码的index.html，这是自定义makefile中的规则：

src/index.html.h: index.html
    xxd -i $<                                                   $@.tmp
    sed 's/unsigned char/static const unsigned char/g' $@.tmp > $@
    sed 's/unsigned int/static const unsigned int/g'   $@     > $@.tmp
    sed 's/};/,0};/g'                                  $@.tmp > $@
    rm -f $@.tmp

makefile仅与模拟器一起用于构建elf x86二进制文件。

当我为ESP8266目标构建时，我想使用platformio构建器自动执行相同的操作。

我在platformio.ini中添加了一个额外的脚本指令：

[env:nodemcuv2]
extra_scripts = pre:generate_index_html_header.py
...

并编写了以下python脚本：

Import("env")

def generate_index_html_header(source, target, env):
    print "Generating index html header"
    env.Execute( "make src/index.html.h" )

env.AddPreAction("generate_index_html_header", generate_index_html_header)

似乎没有执行，因为在构建日志中看不到跟踪“ Generating ...”：

我确定没有执行我的python“额外脚本”，因为如果我手动删除生成的文件“ index.html.h”，则生成文件会出现以下错误：

src/Serveur.cpp:3:24: fatal error: index.html.h: No such file or directory
