ART-Pi SDK在Linux环境下编译不通过问题

发布于 2020-11-08 21:46:01 浏览：1901 订阅该版

本人对于RT-Thread算是新手一枚，平时用的最多的是Linux开发环境，Windows下RT-Studio开发是方便，但编译速度相对比较慢，想尝试在linux下编译ART-Pi SDK。

Linux环境如下：
* Win10 WSL
* Ubuntu 20.0.4
* `gcc version 9.2.1 20191025 (release) [ARM/arm-9-branch revision 277599] `

注：RT-Thread的相关配置是在Windows下已经配置好生成rtconfig.h,及确保新引入的模块已经加入到SConscript，没有使用env配置.

遇到的问题如下3个问题：

1、在SDK下的工程目录下执行`scons --target=makefile`,编译过程正常，但无文件生成；
```
$ scons --target=makefile
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
scons: building associated VariantDir targets: build
CC build/applications/main.o
CC build/board/CubeMX_Config/Core/Src/stm32h7xx_hal_msp.o
CC build/board/board.o
CC build/board/drv_mpu.o
... ...
CC build/packages/webnet-v2.0.2/src/wn_utils.o
AS libraries/STM32H7xx_HAL/CMSIS/Device/ST/STM32H7xx/Source/Templates/gcc/startup_stm32h750xx.o
LINK rt-thread.elf
arm-none-eabi-objcopy -O binary rt-thread.elf rtthread.bin
arm-none-eabi-size rt-thread.elf
scons: done building targets.

**2、执行scons命令，出错**
 scons
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
scons: building associated VariantDir targets: build

```

3、scons --menuconfig执行出错
```
$ scons --menuconfig
scons: Reading SConscript files ...
AttributeError: 'str' object has no attribute 'load_config':
  File "/mnt/e/STM32/STM32H750XB_ART_Pi/SConstruct", line 44:

```
    
主要遇到以上3个问题，不确定是WSL编译环境导致，还是本身ART-Pi的SDK对Linux下的支持不是很完善。
