Build SCON和从根目录和子目录生成

我正在尝试烤饼，但在安排时遇到了问题。我有两个相关项目，一个是生产代码，另一个是按照以下方式安排的测试：

• 根
• 根/生产
• 根/单元测试

我想配置我的构建，以便键入：

SCON-从根目录到构建两者

从生产到仅生成生产代码的SCON

从单元测试到仅构建单元测试的SCON

现在我该怎么做呢？ 如果我在根目录下有SConstruct，在生产和单元测试中有SConscript，我只能从根目录下构建。但如果我在每一级都有SConscript，Root的SConscript调用subdirs中的SConscript：

    # Just call Sconscripts for src and unitTests
    SConscript('production/SConstruct')
    SConscript('unitTests/SConstruct')

---

然后，虽然它确实按照预期构建，但它会发出大量关于为目标（…）指定了两个不同环境的警告。。在这种情况下，生产和测试之间的构建确实非常相似，但一旦我让SCON按我所希望的方式工作，我就会转而管理一系列不一定相关的更大项目

我建议在每个目录中使用一个sconstuct，在每个目录中使用一个SConscript。SConstruct脚本只需调用SConscripts，所有的逻辑都在这里。大概是这样的：

Root/SConstruct
Root/Production/SConstruct
Root/Production/SConscript
Root/UnitTests/SConstruct
Root/UnitTests/SConscript

每个文件的内容可以如下：

根目录/SConstruct

env = Environment()

# build stuff in this dir

# now call subdir SConscripts
SConscript('Root/Production/SConscript', exports='env')
SConscript('Root/UnitTests/SConscript',  exports='env')

env = Environment()

SConscript('SConscript', exports='env')

# This SConscript will be called either from the Root/SConstruct
# or Root/Production/SConstruct

Import('env')

# Build stuff here

env = Environment()

SConscript('SConscript', exports='env')

# This SConscript will be called either from the Root/SConstruct
# or Root/UnitTests/SConstruct

Import('env')

# Build stuff here

Root/Production/SConstruct

env = Environment()

# build stuff in this dir

# now call subdir SConscripts
SConscript('Root/Production/SConscript', exports='env')
SConscript('Root/UnitTests/SConscript',  exports='env')

env = Environment()

SConscript('SConscript', exports='env')

# This SConscript will be called either from the Root/SConstruct
# or Root/Production/SConstruct

Import('env')

# Build stuff here

env = Environment()

SConscript('SConscript', exports='env')

# This SConscript will be called either from the Root/SConstruct
# or Root/UnitTests/SConstruct

Import('env')

# Build stuff here

Root/Production/SConscript

env = Environment()

# build stuff in this dir

# now call subdir SConscripts
SConscript('Root/Production/SConscript', exports='env')
SConscript('Root/UnitTests/SConscript',  exports='env')

env = Environment()

SConscript('SConscript', exports='env')

# This SConscript will be called either from the Root/SConstruct
# or Root/Production/SConstruct

Import('env')

# Build stuff here

env = Environment()

SConscript('SConscript', exports='env')

# This SConscript will be called either from the Root/SConstruct
# or Root/UnitTests/SConstruct

Import('env')

# Build stuff here

Root/UnitTests/SConstruct

env = Environment()

# build stuff in this dir

# now call subdir SConscripts
SConscript('Root/Production/SConscript', exports='env')
SConscript('Root/UnitTests/SConscript',  exports='env')

env = Environment()

SConscript('SConscript', exports='env')

# This SConscript will be called either from the Root/SConstruct
# or Root/Production/SConstruct

Import('env')

# Build stuff here

env = Environment()

SConscript('SConscript', exports='env')

# This SConscript will be called either from the Root/SConstruct
# or Root/UnitTests/SConstruct

Import('env')

# Build stuff here

Root/UnitTests/SConscript

env = Environment()

# build stuff in this dir

# now call subdir SConscripts
SConscript('Root/Production/SConscript', exports='env')
SConscript('Root/UnitTests/SConscript',  exports='env')

env = Environment()

SConscript('SConscript', exports='env')

# This SConscript will be called either from the Root/SConstruct
# or Root/Production/SConstruct

Import('env')

# Build stuff here

env = Environment()

SConscript('SConscript', exports='env')

# This SConscript will be called either from the Root/SConstruct
# or Root/UnitTests/SConstruct

Import('env')

# Build stuff here

请注意，SConscript脚本不会创建

环境（）

，而是使用从根/SConstruct传入的环境，或者使用同一目录中的SConstruct

还考虑使用<代码> ValuthIdir < /Code >参数，使用<代码> SCONScript（）/<代码>函数调用，将所有生成输出放在除了代码目录结构之外的目录结构中。这样做时，还要考虑使用<代码>重复= 0 参数，使用<代码> SCONScript（）/<代码>函数调用。SConscript函数很详细，并且。

@Puchatek，很乐意帮助：）
