编译错误解决办法：fork/exec:…\arm-none-eabi-g++.exe: The filename or extension is too long

解决方案来自Edge Impulse

当使用Arduino编译STM或Arduino文件时，当要编译的目标文件列表超过命令行中的Windows最大字符数（32k）时，通常会引发此错误。

如果使用的2.0版本以下IDE版本，可参考以下方法：

如果是Arduino则使用前两种方法即可，Adafruit、esp32、STM32参照后面的方法

1.在Arduino mbed目录下，即：C:\Users\(自己的用户名)\AppData\Local\Arduino15\packages\arduino\hardware\mbed\1.1.4\ （版本号可能不同）
创建platform.local.txt 并粘贴以下代码 :

## Customized platform.local.txt to compile for mbed targets under Windows
## This recipe works around the Windows limit of 32k characters in a cmd line by calling .o files from a text file during linking
## Install: put file under your mbed sub-directory - ie: C:\Users\MYUSER\AppData\Local\Arduino15\packages\arduino\hardware\mbed\1.1.4
## You can also find the local arduino folder in the IDE under File -> Preferences -> see preferences.txt location in the bottom part of the window## hooks# create a txt file with all object file paths from libraries and sketch folders (core\variant.cpp.o needed too for linking)
recipe.hooks.linking.prelink.1.pattern=cmd /c dir /b /s {build.path}\sketch\*.o > {build.path}\obj_files_tmp.txt
recipe.hooks.linking.prelink.2.pattern=cmd /c "dir /b /s {build.path}\libraries\*.o >> {build.path}\obj_files_tmp.txt 2>nul & exit 0"
recipe.hooks.linking.prelink.3.pattern=cmd /c echo "{build.path}\core\variant.cpp.o" >> {build.path}\obj_files_tmp.txt# replace \ by \\ in file paths (otherwise escaped by linker) and save in new txt file
recipe.hooks.linking.prelink.4.pattern=cmd /v /c "@echo off && for /f %a in ({build.path}\obj_files_tmp.txt) do (set line=%a && set line=!line:\=\\! && echo !line! >> {build.path}\obj_files.txt)"# delete txt file after linking
recipe.hooks.linking.postlink.1.pattern=cmd /c del {build.path}\obj_files.txt## modify compile patterns (@{build.path}\obj_files.txt)recipe.c.combine.pattern="{compiler.path}{compiler.c.elf.cmd}"  "-L{build.path}" {compiler.c.elf.flags} {compiler.c.elf.extra_flags} "@{compiler.mbed.ldflags}" "-T{build.variant.path}/{build.ldscript}" "-Wl,-Map,{build.path}/{build.project_name}.map" --specs=nano.specs --specs=nosys.specs {compiler.ldflags} -o "{build.path}/{build.project_name}.elf" @{build.path}\obj_files.txt -Wl,--whole-archive "{build.path}/{archive_file}" {compiler.mbed} -Wl,--no-whole-archive -Wl,--start-group {compiler.mbed.extra_ldflags} {compiler.libraries.ldflags} -Wl,--end-group

如图所示：

2.在Arduino samd目录下，即：C:\Users\(自己的用户名)\AppData\Local\Arduino15\packages\arduino\hardware\samd\1.1.4
创建platform.local.txt 并粘贴以下代码 :

## Customized platform.local.txt to compile for SAMD21 targets under Windows
## This recipe works around the Windows limit of 32k characters in a cmd line by calling .o files from a text file during linking
## Install: put file under your mbed sub-directory - ie: C:\Users\MYUSER\AppData\Local\Arduino15\packages\arduino\hardware\samd\1.8.9
## You can also find the local arduino folder in the IDE under File -> Preferences -> see preferences.txt location in the bottom part of the window## hooks# create a txt file with all object file paths from libraries and sketch folders (core\variant.cpp.o needed too for linking)
recipe.hooks.linking.prelink.1.pattern=cmd /c dir /b /s {build.path}\sketch\*.o > {build.path}\obj_files_tmp.txt
recipe.hooks.linking.prelink.2.pattern=cmd /c "dir /b /s {build.path}\libraries\*.o >> {build.path}\obj_files_tmp.txt 2>nul & exit 0"
recipe.hooks.linking.prelink.3.pattern=cmd /c echo "{build.path}\core\variant.cpp.o" >> {build.path}\obj_files_tmp.txt# replace \ by \\ in file paths (otherwise escaped by linker) and save in new txt file
recipe.hooks.linking.prelink.4.pattern=cmd /v /c "@echo off && for /f %a in ({build.path}\obj_files_tmp.txt) do (set line=%a && set line=!line:\=\\! && echo !line! >> {build.path}\obj_files.txt)"# delete txt file after linking
recipe.hooks.linking.postlink.1.pattern=cmd /c del {build.path}\obj_files.txt## modify compile patterns (@{build.path}\obj_files.txt)
recipe.c.combine.pattern="{compiler.path}{compiler.c.elf.cmd}"  "-L{build.path}" {compiler.c.elf.flags} {compiler.c.elf.extra_flags} "-T{build.variant.path}/{build.ldscript}" "-Wl,-Map,{build.path}/{build.project_name}.map" --specs=nano.specs --specs=nosys.specs {compiler.ldflags} -o "{build.path}/{build.project_name}.elf" @{build.path}\obj_files.txt {compiler.libraries.ldflags} -Wl,--start-group {compiler.arm.cmsis.ldflags} -lm "{build.path}/{archive_file}" -Wl,--end-group

3.如果是Adafruit，则
在Arduino Adafruit samd目录下，即：C:\Users\(自己的用户名)\AppData\Local\Arduino15\packages\adafruit\hardware\samd\1.6.3
创建platform.local.txt 并粘贴以下代码 :

## Install: put file under your mbed sub-directory - ie: C:\Users\MYUSER\AppData\Local\Arduino15\packages\arduino\hardware\samd\1.8.9
## You can also find the local arduino folder in the IDE under File -> Preferences -> see preferences.txt location in the bottom part of the window## hooks# create a txt file with all object file paths from libraries and sketch folders (core\variant.cpp.o needed too for linking)
recipe.hooks.linking.prelink.1.pattern=cmd /c dir /b /s {build.path}\sketch\*.o > {build.path}\obj_files_tmp.txt
recipe.hooks.linking.prelink.2.pattern=cmd /c "dir /b /s {build.path}\libraries\*.o >> {build.path}\obj_files_tmp.txt 2>nul & exit 0"
recipe.hooks.linking.prelink.3.pattern=cmd /c echo "{build.path}\core\variant.cpp.o" >> {build.path}\obj_files_tmp.txt# replace \ by \\ in file paths (otherwise escaped by linker) and save in new txt file
recipe.hooks.linking.prelink.4.pattern=cmd /v /c "@echo off && for /f %a in ({build.path}\obj_files_tmp.txt) do (set line=%a && set line=!line:\=\\! && echo !line! >> {build.path}\obj_files.txt)"# delete txt file after linking
recipe.hooks.linking.postlink.1.pattern=cmd /c del {build.path}\obj_files.txt## modify compile patterns (@{build.path}\obj_files.txt)
recipe.c.combine.pattern="{compiler.path}{compiler.c.elf.cmd}"  "-L{build.path}" {compiler.c.elf.flags} {compiler.c.elf.extra_flags} "-T{build.variant.path}/{build.ldscript}" "-Wl,-Map,{build.path}/{build.project_name}.map" --specs=nano.specs --specs=nosys.specs {compiler.ldflags} -o "{build.path}/{build.project_name}.elf" @{build.path}\obj_files.txt {compiler.libraries.ldflags} -Wl,--start-group {compiler.arm.cmsis.ldflags} "-L{build.variant.path}" -lm "{build.path}/{archive_file}" -Wl,--end-group

4.如果是ESP32，则在Arduino ESP32目录下，即：C:\Users\(自己的用户名)\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.4
创建platform.local.txt 并粘贴以下代码 :


## Customized platform.local.txt to compile for ESP32 targets under Windows
## This recipe works around the Windows limit of 32k characters in a cmd line, creating an archive with sketch and libraries object files before linking
## Install: put file under your esp32 sub-directory - ie:C:\Users\MYUSER\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.4

recipe.hooks.linking.prelink.4.pattern=cmd /v /c "@echo off && for /f %a in ({build.path}\obj_files.txt) do ({compiler.path}{compiler.ar.cmd} {compiler.ar.flags} {compiler.ar.extra_flags} {build.path}\custom_lib.a %a)"# delete txt file and archive after linking
recipe.hooks.linking.postlink.1.pattern=cmd /c del {build.path}\obj_files.txt
recipe.hooks.linking.postlink.2.pattern=cmd /c del {build.path}\custom_lib.a## modify compile patterns (use custom_lib.a instead of object_files)
recipe.c.combine.pattern="{compiler.path}{compiler.c.elf.cmd}" {compiler.c.elf.flags} {compiler.c.elf.extra_flags} -Wl,--start-group "{build.path}\custom_lib.a" "{archive_file_path}" {compiler.c.elf.libs} -Wl,--end-group -Wl,-EL -o "{build.path}/{build.project_name}.elf"

5.如果是STM32，则在Arduino STM32目录下，即：C:\Users\(自己的用户名)\AppData\Local\Arduino15\packages\esp32\hardware\stm32\1.9.0

进行以上操作后，测试编译成功
