Question

我正在尝试构建/安装名为envoy的项目的依赖项。

项目目录如下：

有两个bazel WORKSPACE文件：

$ find . -iname WORKSPACE
./WORKSPACE 
./ci/WORKSPACE

我想我必须从顶层目录构建bazel本机依赖关系，但是我不知道如何指定目标BUILD文件。您能否在bazel build上提出建议命令来实现那个目标？

编辑：我正在尝试在此处https://github.com/envoyproxy/envoy/blob/master/bazel/README.md

上构建步骤2中提到的内容。

编辑＃2：：进行$ bazel build //source/exe:envoy

时

我遇到以下错误

能否请您进一步提出建议？

编辑＃3：为完整起见，我在scl下运行此命令，以便获得较新的GCC版本

- name: "Install envoy dependencies"
        yum: name="{{ item }}" state=latest
        with_items:
          - cmake
          - libtool
          - libstdc++
          - bazel
          - centos-release-scl
          - devtoolset-7-gcc-c++   # scl enable devtoolset-7 bash
        environment:
          http_proxy: "{{ prx.http }}"
          https_proxy: "{{ prx.https }}"

表示我先输入scl enable devtoolset-7 bash，然后输入通常的内容

Answer 1

从DEVELOPER.md开始构建Envoy：

$ bazel build //source/exe:envoy

此//source/exe:envoy目标在source/exe/BUILD中定义。

要运行所有测试：

$ bazel test //test/...

...递归引用所有目标。

要运行特定的测试，例如test/common/http/BUILD中定义的async_client_impl_test。 //test/common/http是程序包名称。

$ bazel test //test/common/http:async_client_impl_test

由于绝对目标标签中的//，因此可以从项目目录中的任何位置运行这些命令。

Answer 2

您可以尝试“进入-u google.golang.org/grpc”并查看其是否有效吗？
