@bazel_skylib//rules:native_binary.bzl
定义native_binary
可用于将本机可执行文件包装在 bazel 目标中的规则。我用它来包装一个packfolder.exe
从 Sciter SDK 调用的打包工具。
我将二进制文件放入我的源代码树中third_party/sciter/packfolder.exe
并编写了这个BUILD
文件。
# third_party/sciter/BUILD
native_binary(name = "packfolder",
src = "packfolder.exe",
out = "packfolder.exe"
)
bazel run third_party/sciter:packfolder
运行没有问题。现在我想在我的自定义cc_sciter_resource
规则中使用这个目标。
# third_party/sciter/sciter_rules.bzl
def _impl(ctx):
in_files = ctx.files.srcs
output_file = ctx.actions.declare_file(ctx.label.name)
ctx.actions.run(
outputs = [output_file],
inputs = in_files,
arguments = [],
executable = ctx.executable.packfolder.path)
return DefaultInfo(files = depset([output_file]))
cc_sciter_resource = rule(
implementation = _impl,
attrs = {
"srcs": attr.label_list(),
"packfolder": attr.label(
default = Label("//third_party/sciter:packfolder"),
executable = True,
cfg = "exec"
),
}
)
问题是,当我尝试构建使用此规则的目标时,比如说
cc_sciter_resource(
name = "hello_world_resource.cpp"
srcs = [...]
)
我收到以下错误。
