使用 bazel 进行初始构建设置，用于在一个最小示例（具有广泛的依赖关系）上测试通用 UI 库。构建设置包括该库的规则和配置。但是，当我扩展此构建时，将依赖项目作为包（BUILD）添加到子文件夹中并将库保留为 new_local_repository - bazel 吐出错误。

它不会将该库的共享二进制文件复制到构建输出。因此，它给出了共享库或所需二进制文件丢失的随机（依赖于任何二进制文件）错误：

ERROR: C:/users/ilya/source/repos/project-cross-platform/project/BUILD:28:10: Copying Execution Dynamic Library failed: missing input file 'external/qt/bin/Qt5Core.dll', owner: '@qt//:bin/Qt5Core.dll'

这是示例工作区文件：workspace(name = "project")

load("@project//:qt_configure.bzl", "local_qt_path")

new_local_repository(
    name = "qt",
    build_file = "//:qt.BUILD",
    path = "./",

qt.构建：

似乎有几个错误，如果删除可能会一起解决问题：

  • 规则“new_”用于添加不是用 Bazel 构建的存储库（请参阅文档）
  • 当使用规则 new_local_repository 依赖不是用 Bazel 构建的 repo 时，您必须指定该 repo 的路径（您这样做了）以及用于构建该 repo 的构建文件。构建文件是相对于其他存储库的根目录简单地定义的，所以简单地 /<BUILD File)。您指定为构建文件(build_file = "//:qt.BUILD",) 的内容看起来错误。

祝你今天过得愉快 ：）
