我应该什么时候使用scon扫描仪与parseDepends和依赖关系？

Question

我为这么长的问题道歉。

下面是我想用scon做的事情

• 在语法文件组件(是语音识别项目)之前构建一个java组件。我的语法文件组件需要java组件来自己编译。
• 使用多处理(-j)

到目前为止正在起作用的是：

• 我们95%的c++代码都是用scon -j4完美构建的。正确地创建了Dependcies树
• 我们的自定义python使用ant从java组件生成.jar。

不起作用的是：

• 当使用-j4时，将在java编译之前调用定制的python，以从语法文件组件生成二进制文件。

下面是生成sideLibrary.jar的scon脚本文件(使用命令)

Import('common_env')
#Grab a copy of the top environment (the one sent by the SConstruct file)
common_env = common_env.Clone()
#Current working directory.
currentDir = common_env['ENV']['LOCALROOT'] + '/' + common_env.sconsGetCWD()
#Launches ant -q
tgts = common_env.Command(target = [currentDir + '/dist', currentDir + '/dialogeditor/lib', currentDir + '/doc/sdtk', currentDir + '/obj', common_env['ENV']['LOCALROOT'] + '/LINK/bin/win32/sideLibrary.jar'], source = 'build.xml', action = 'ant -q -f $SOURCE')
#Cleans the generated folders
common_env.Clean(tgts, '')

下面是用于生成语法二进制文件(使用自定义生成器)的scon脚本文件：

Import('common_env')
#Creates a copy of the build environment sent from the SConstruct file.
common_env = common_env.Clone()
#Because this component is only compiled in win32
if (common_env['ENV']['CONFIG'] == "win32"):
    #Language of the grammar.
    common_env['ENV']['LANGUAGE'] = 'en'
    #Language pack.
    common_env['ENV']['LANGUAGE_PACK'] = 'English.America.3.3.0'
    #Grammar name
    common_env['ENV']['GRAMMAR_NAME'] = 'faa'
    #Compiles the grammar using a custom builder.
    common_env.buildGrammar(src = common_env['ENV']['LOCALROOT'] + '/LINK/bin/win32/sideLibrary.jar')

有人告诉我，将src = calling _env‘env’+‘/LINK/bin/bin/bin 32/ sideLibrary.jar . our’传递给我们的定制构建器时，他告诉scon，在调用buildGrammar之前，他必须自动地从buildGrammar中等待。我真的很怀疑，因为文档只说：

源: Node对象的列表，表示此构建器函数用于构建目标的源。

这就引出了扫描仪、ParseDepens和取决于 (我已经阅读了关于它们的scon文档)。

在我的脑海中，还不清楚我应该使用哪个组件来完成我想要做的事情:在使用-j4的另一个组件之前强制编译java组件。

能给我点一下灯笼吗？

谢谢

Answer 1

嗯，我不确定这个问题能帮到谁，但我觉得至少回答我的问题很重要。

因此，对于以scon开头的每个人，始终使用"source=“作为函数参数。我的所有问题(-j4不起作用)都与以下事实完全相关:当我调用自定义构建器时，我使用它的方式是"buildGrammar(src="blabla")“。这是错误的。必须是"buildGrammar(source="blabla")

Answer 2

您可能不需要Scanner、ParseDepends或Depends。请看一下我们的ToolsForFools指南，看看如何为您的生成器提供一个Emitter。

SCons需要知道的是，文件sideLibrary.jar是由系统中的另一个生成器创建的(整个构建描述)。如果您已经显式地将sideLibrary.jar指定为creating的目标，那么这应该是现成的。然后，SCons知道sideLibrary.jar既是一个生成器的目标，也是另一个生成器的源文件。所以它可以正确地安排单个构建步骤..。

但是，如果您的sideLibrary.jar只是另一个构建命令的副产品：

env.YourBuilder('other.jar', Glob('*.java'))

，然后您需要为这种类型的构建定义一个特殊的发射器，这样SCons就可以同时看到构建other.jar和创建sideLibrary.jar之间的联系。

我希望这能让你更清楚。如果您仍然很难让它正常工作，请查看我们的UserMailing列表(scons-users@scons.org，也请参阅http://scons.org/lists.html)，在这里我们可以更详细地讨论您的问题，您可能会获得更多有用的参考指针。
