Call to build toolchains (rules_foreign_cc_dependencies()) is not working

Hello,

I don't have a repo to reference. This is a problem I am experiencing with the source code at my job. I am migrating the github dependencies to our personal repo. This just involved downloading the packages from github and adding them to out repo. Then, referencing the link in the source. Json.

I am experiencing a build error when calling rules_foreign_cc_dependencies(). It is apparently trying to build toolchains from github, but my system does not have access to github (i.e. it does not have internet connectivity) so it is failing. I need a work-around for this.

How can I manually/automatically include all of the toolchain dependencies built by rules_foreign_cc_dependencies()? What are the dependencies? Where can I download/include them in my WORKSPACE/BUILD files?

Start at the rules_foreign_cc_dependencies() entry point and review how its dependencies are referenced from WORKSPACE and BUILD files. Reproduce the offline build failure in an environment without GitHub access, then identify the complete dependency set and verify that an offline configuration can include it without fetching from GitHub.
