编译impl出现问题：bzl依赖库

[reacher1130]

f如果使用官方interconnection-impl的源码，不修改repositories.bzl，其中
def ic_impl_deps():
_com_github_nlohmann_json()
maybe(
git_repository,
name = "spulib",
commit = SPU_COMMIT_ID,
remote = "{}/{}.git".format(SECRETFLOW_GIT, SPU_REPOSITORY),
# remote = "https://github.com/reacher1130/spu.git",
)
这是可以bazel编译通过的；
如果将其中的spu的git依赖库改成自己fork过的spu的main分支，并且spu中的repositories.bzl的yacl的git依赖库也改成自己fork过的yacl的main分支，就会出现如下编译问题：
ERROR: /root/develop/interconnection-impl/ic_impl/algo/lr/BUILD.bazel:19:11: error loading package '@spulib//libspu/mpc': at /root/.cache/bazel/_bazel_root/b12e4e3f9a14f11e902c5f6f1fe2e080/external/spulib/bazel/spu.bzl:20:6: at /root/.cache/bazel/_bazel_root/b12e4e3f9a14f11e902c5f6f1fe2e080/external/yacl/bazel/yacl.bzl:20:6: at /root/.cache/bazel/_bazel_root/b12e4e3f9a14f11e902c5f6f1fe2e080/external/rules_foreign_cc/foreign_cc/defs.bzl:8:6: at /root/.cache/bazel/_bazel_root/b12e4e3f9a14f11e902c5f6f1fe2e080/external/rules_foreign_cc/foreign_cc/ninja.bzl:8:5: at /root/.cache/bazel/_bazel_root/b12e4e3f9a14f11e902c5f6f1fe2e080/external/rules_foreign_cc/foreign_cc/private/framework.bzl:5:6: at /root/.cache/bazel/_bazel_root/b12e4e3f9a14f11e902c5f6f1fe2e080/external/bazel_features/features.bzl:3:6: Unable to find package for @bazel_features_globals//:globals.bzl: The repository '@bazel_features_globals' could not be resolved: Repository '@bazel_features_globals' is not defined. and referenced by '//ic_impl/algo/lr:lr_handler'

需求：对yacl其中相关互联互通部分的代码进行修改和日志输出，因此需要在bzl中修改为自己的yacl库，非常感谢！

或者出现如下问题：

或者随机出现：
ERROR: /root/develop/interconnection-impl/ic_impl/BUILD.bazel:74:11: error loading package '@yacl//yacl/base': at /root/.cache/bazel/_bazel_root/b12e4e3f9a14f11e902c5f6f1fe2e080/external/yacl/bazel/yacl.bzl:20:6: at /root/.cache/bazel/_bazel_root/b12e4e3f9a14f11e902c5f6f1fe2e080/external/rules_foreign_cc/foreign_cc/defs.bzl:4:6: at /root/.cache/bazel/_bazel_root/b12e4e3f9a14f11e902c5f6f1fe2e080/external/rules_foreign_cc/foreign_cc/cmake.bzl:140:5: at /root/.cache/bazel/_bazel_root/b12e4e3f9a14f11e902c5f6f1fe2e080/external/rules_foreign_cc/foreign_cc/private/framework.bzl:5:6: at /root/.cache/bazel/_bazel_root/b12e4e3f9a14f11e902c5f6f1fe2e080/external/bazel_features/features.bzl:3:6: Unable to find package for @bazel_features_globals//:globals.bzl: The repository '@bazel_features_globals' could not be resolved: Repository '@bazel_features_globals' is not defined. and referenced by '//ic_impl:util'

yacl 最新版本更新了 rules_foreign_cc 包。需要在 interconnection-impl 的 WORKSPACE 文件中增加下面两行代码：

load("@bazel_features//:deps.bzl", "bazel_features_deps")
bazel_features_deps()

参看 SPU 的配置文件：https://github.com/secretflow/spu/blob/main/WORKSPACE#L56

[reacher1130]

但yacl最新版本的workspace里存在这两句load和依赖，因此在interconnection-impl的workspace里增加这两行代码时会提示重复：
ERROR: Failed to load Starlark extension '@bazel_features//:deps.bzl'.
Cycle in the workspace file detected. This indicates that a repository is used prior to being defined.
The following chain of repository dependencies lead to the missing definition.

• @bazel_features
  This could either mean you have to add the '@bazel_features' repository with a statement like http_archive in your WORKSPACE file (note that transitive dependencies are not added automatically), or move an existing definition earlier in your WORKSPACE file.
  ERROR: Error computing the main repository mapping: cycles detected during computation of main repo mapping

[shaojian-ant]

interconnection-impl 不会用到 yacl WORKSPACE 里面的代码，只用到 yacl repositories.bazel 里面的代码。你的 WORKSPACE 文件是怎么修改的呢

[shaojian-ant]

只需要把 下面代码放在 interconnection-impl WORKSPACE 文件的最后应该就可以

load("@bazel_features//:deps.bzl", "bazel_features_deps")
bazel_features_deps()
