我可以指示bazel发出".elf"消息吗?后缀为可执行文件? [英] Can I instruct bazel to emit a ".elf" suffix to executables?

问题描述

cc_binary(在osx/linux上)创建不带后缀的可执行文件.这是有道理的，因为这些平台上的标准是不使用扩展.

cc_binary (on osx / linux) creates executables with no suffix. This makes sense, since the standard on those platforms is to not use extensions.

但是，当通过自定义CROSSTOOL将Bazel用作交叉编译器时，我希望Bazel发出带有显式.elf后缀的elf文件.

When using Bazel as a cross-compiler through a custom CROSSTOOL, though, I'd like Bazel to emit an elf file with an explicit .elf suffix.

通过CROSSTOOL或自定义的重命名"规则是否可行?

Is this possible, either through CROSSTOOL or a custom "rename" rule?

推荐答案

您可以将cc_binary命名为"foo.elf"，而bazel将会对其进行构建.或者，您也可以使用genrule进行重命名.

You can name your cc_binary 'foo.elf' and bazel will just build it. Or you can use genrule to do the renaming afterwards.

现在，如果您需要使用多个工具链来构建相同的cc_binary，并且每次生成不同的扩展名，那将更加棘手.但是genrule也可以在那里工作.

Now if you need to build the same cc_binary with multiple toolchains, each time producing a different extension, that's a little bit more tricky. But genrule will work there too.
