目标平台
[自 OOo 3.0 起]
可以使用 description.xml 中的 平台 标签来确定一个扩展的目标平台。
请注意 这个平台标签只在安装过程中使用以确定用户使用何种平台。这无法用来识别扩展，详见 标识符文档。
如果没有平台标签，那么就默认为所有平台适用。这与显示注明所有平台适用是一样的：
<platform value="all" />
属性值可以包含多个平台标记，由逗号分隔：
<platform value="windows_x86,linux_x86,solaris_sparc" />
只有在其中一个平台标签与用户平台相匹配时扩展才能被安装。特殊的“all"平台表示所有平台。也就是说，这个扩展可以安装在所有平台上。相反的
<platform value=" " />将防止在所有平台安装。
平台标签（Flatform token）需要由 OOo 来定义。每个标签可以表示一个特定的平台集。当前已定义的标签在 平台标签章节列出。
Do not confuse these tokens with those used to specify a native library in the manifest.xml. We will unify the use of the tokens in one of the future releases.
Platform Tokens

The tokens with the description 'Not yet supported' will be supported at a later time (see issue 88578).
Backward Compatibility of Platforms
Often an OOo built for 32bit platform will run on the respective 64bit platform as well. In this case the platform element would only need the value of the 32bit platform. The reason is, that the extension manager compares the platform of the extension with the platform for which OOo was built. Here are some examples:
| Extension platform | OOo build for platform | Platform where OOo runs | Result |
|---|---|---|---|
| Linux_x86 | Linux_x86 | Linux_x86 | ok |
| Linux_x86 | Linux_x86 | Linux_x86_64 | ok |
| Linux_x86 | Linux_x86_64 | Linux_x86_64 | fails |
| Linux_x86_64 | Linux_x86 | Linux_x86_64 | fails |
Generating the Platform String in the Build Environment
When it is necessary to generate the description.xml and the platform string during in the build process one can utilize the rtlbootstrap.mk which is contained in the inc folder. rtlbootstrap.mk is build in module sal and contains values for the operating system and processor. For example:
RTL_OS:=Linux RTL_ARCH:=x86
These values correspond to the values of the bootstrap variable ${_OS} and ${_ARCH}. The file can be included in the makefile which generates the description.xml and use
PLATFORMSTRING = $(RTL_OS:l)_$(RTL_ARCH:l)
to form the string.
