SConscript scons脚本

如何编写scons脚本让生成的目标文件在build文件夹下？

发布于 2021-11-08 10:58:39 浏览：353

如图，生成的.o 文件在源码同一个文件夹下了，但是其它的文件夹的源码生成的.o却是在build文件夹下。想请教一下怎么修改

这是对应该问价夹的 scons脚本

VariantDir 这个接口应该是你需要的 ref:https://www.scons.org/doc/3.1.2/HTML/scons-user.html

Hi @myLLgf ：我曾经也有这个疑问：
你可以试下在下面的代码中加入如下修改。
比如在bsp的Sconstruct的代码如下

objs.extend(SConscript(os.path.join(libraries_path_prefix, 'drivers', 'SConscript')))

# include cmsis
objs.extend(SConscript(os.path.join(libraries_path_prefix, 'cmsis', 'SConscript')))

修改如下：

objs.extend(SConscript(os.path.join(libraries_path_prefix, 'drivers', 'SConscript'),variant_dir='build/drivers'))

# include cmsis
objs.extend(SConscript(os.path.join(libraries_path_prefix, 'cmsis', 'SConscript'),variant_dir='build/cmsis'))

具体的可以根据自己的bsp下面做对应的修改。这样的话，编译后的.o文件会被放到build目录下面

欢迎对bsp进行PR修改，我看很多bsp都没有修改。

ch32_library = 'CH32F10x_StdPeriph_Driver'
rtconfig.BSP_LIBRARY_TYPE = ch32_library

ch32_common_drivers = 'ch32_drivers'
# include libraries
objs.extend(SConscript(os.path.join(libraries_path_prefix, ch32_library, 'SConscript'), variant_dir= 'build/' + ch32_library + '/src', duplicate=0))

# common include drivers
objs.extend(SConscript(os.path.join(libraries_path_prefix, ch32_common_drivers, 'SConscript'), variant_dir='build/' + ch32_common_drivers + '/src', duplicate=0))

# make a building
DoBuilding(TARGET, objs)

测试了一下，标准库和适配的rt驱动都能在build目录下生成，唯独startup那个汇编文件不行，暂时还没想到怎么处理

startup_path_prefix = SDK_LIB

if rtconfig.CROSS_TOOL == 'keil':
    src += [startup_path_prefix + '/CH32F10x_StdPeriph_Driver/CMSIS/WCH/CH32F10x/Source/ARM/startup_ch32f10x.s']
if rtconfig.CROSS_TOOL == 'gcc':
    src += [startup_path_prefix + '/CH32F10x_StdPeriph_Driver/CMSIS/WCH/CH32F10x/Source/GCC/startup_ch32f10x.S']

.s可能编译器不一样吧，如果觉得答案有帮助的话，欢迎采纳

找了rt-thread/bsp/stm32/libraries/HAL_Drivers/SConscript比对了下，你驱动Glob试试看？

谢谢了，本来我是按照右边的脚本去编译的，一样，然后我才改成了左边，结果没什么区别。

@myLLgf 这么说的话，可能问题不在你当前目录的Sconscript，往上一级Sconstruct查一下：
即类似这样个图里的位置：

可以的话，把这个Sconstruct文件也贴出来看下。

感谢各位的帮助！根目录下的 sconstruct 文件中

# include libraries
objs.extend(SConscript(os.path.join(libraries_path_prefix, stm32_library, 'SConscript')))

# include drivers
objs.extend(SConscript(os.path.join(libraries_path_prefix, 'HAL_Drivers', 'SConscript')))

这两行可以不要, 在 Library 文件夹里加个 sconsscript 把子文件夹的脚本自动添加 objs 就行了

import os
from building import *

cwd = GetCurrentDir()
objs = []
list = os.listdir(cwd)

for d in list:
    path = os.path.join(cwd, d)
    if os.path.isfile(os.path.join(path, 'SConscript')):
        objs = objs + SConscript(os.path.join(d, 'SConscript'))

Return('objs')

这样生成的目标文件最寻了 building.py 里的规则，都在build目录下

试了一下，对于startup.s/stratup.S依然会在库里面生成，折中的办法就是将borad/sconscript判断使用的startup语句移到库中的sconscript实现:

path = [
    cwd + '/CMSIS',
    cwd + '/CMSIS/WCH/CH32F10x/Include',
    cwd + '/StdPeriph_Driver/inc']


if rtconfig.CROSS_TOOL == 'keil':
    src += ['CMSIS/WCH/CH32F10x/Source/ARM/startup_ch32f10x.s']
if rtconfig.CROSS_TOOL == 'gcc':
    src += ['CMSIS/WCH/CH32F10x/Source/GCC/startup_ch32f10x.S']

group = DefineGroup('ch32f10x_lib', src, depend = [''], CPPPATH = path)

Return('group')

这样的话就可以，我是用ch32测试的
