是否存在使用中的所有已知目标三元组的列表? [英] Does a list of all known target triplets in use exist?

问题描述

使用交叉编译工具时，通常必须提供目标三元组".给出的例子

When cross compiling tools, you will often have to provide "a target triplet". Example given

• i686-pc-linux-gnu
• arm-none-linux-gnueabi
• powerpc-unknown-linux

以此类推...

这些三胞胎有时实际上是四个组成部分，具有以下形式:

These triplets, which are sometimes in fact four components, have the following form:

< CPU>-<制造商> [-< KERNEL>]-< OS>

内核是可选的，制造商可以是未知"或无"之类的东西，因为它通常是不相关的.

Kernel is optional and manufacturer can be something like "unknown" or "none", since it is often not relevant.

我还没有找到一个记录所有可能在此处使用的值的页面.我知道所有组件几乎都是自由样式"，因此没有官方标准会强迫您使用官方标准化列表中的组件.然而，工具设计者和配置脚本编写者希望用户指定其三联体到他们的工具/脚本中，因此他们必须牢记一些可能的值，并且应该有类似非官方列表"的工具制造者，脚本编写者和用户可以使用这些三元组.参考.

What I haven't found yet is a page that documents all possible values to be used here. I know that all components are pretty much "free style", so there is no official standard that would force you to use components from an official standardized list. Yet tool designers and configure script writers expect users to specify those triplets to their tools/scripts, so they must have some possible values in mind and there ought to be something like an "unofficial list" tool makers, script writers and users can use as a reference.

有人找到过这样的名单吗?

Has anyone ever found such a list?

推荐答案

是的，在libtool源文件中.它称为平台.它可能不完整.还有一个名为 config.sub 的文件，该文件在运行 autoreconf 时生成.这些可能是最新的/完整的.

Yes, there is in the libtool sources. It's called PLATFORMS. It's probably not complete. There's also a file called config.sub that gets generated when autoreconf is run. Those are probably more up to date/complete.

但是根据定义，您要的东西似乎是不可能的.如果有一些制造商推出的新的"xyz" CPU，它将暂时不会出现在列表中.

But by definition, what you are asking for seems kind of impossible. If there's a new 'xyz' CPU that some manufacturer rolls out it's not going to appear on the list for a time.

那么在这种情况下， configure 脚本编写者是做什么的呢?我的解决方案如下.我在名为 bootstrap.sh 的脚本中调用了 autoreconf ，该脚本在 GNU shtool 中的sed包装器脚本)都可以插入在 autoreconf 将其复制到AC_CONFIG_AUX_DIR后，我需要进入 config.sub .

So what's a configure script writer do in that case? My solution is the following. I have autoreconf called in a script called bootstrap.sh that sets up a few things before the build as advocated by the Goat Book folks. This script uses sed (well, technically the sed wrapper script in GNU shtool) to insert what I need into config.sub after autoreconf copies it to AC_CONFIG_AUX_DIR.

幸运的是， config.sub 文件带有时间戳，因此如果/在将"xyz"添加到官方"列表时，您仅可以测试时间戳.然后，将新的官方" config.sub 添加到压缩包中，并使用 bootstrap.sh 来测试 autoreconf 是否正在编写最新的足够的 config.sub .如果还不够，请用新的副本复制旧的副本.

Fortunately, config.sub files are timestamped so if/when 'xyz' is added to the "official" list you can just test the timestamp. Then you'll add the new "official" config.sub to your tarball and use bootstrap.sh to test if autoreconf is writing a recent enough config.sub. If it's not a recent enough, copy over the old one with the new one.
