Building neovim in corporate environment

Neovim
1

I am trying to build neovim on a linux box in corporate environment. By corporate, I mean:

  • Internet access is only via proxy server
  • Proxy server requires user/pass authentication
  • The password is very strong, contains special characters

So far, I am failing miserably. When I put proxy details into ~/.wgetrc or ~/.curlrc, the corresponding utilities work fine. However, I am unable to make CMake build process to recognise them… I tried playing with HTTP(S)_PROXY environment variables, but unsuccessfully. If I put password as is, I get wrong proxy format errors. If I replace special characters with 0x{ascii hex} or %{ascii hex}, this does not work either…

Then I tried manual download of the missing modules. This kind of worked (very tediously) with tarballs in .deps/build/downloads, but now build fails with the following message, and I am not sure what to do next:

Any help would be appreciated.

And my personal experience building neovim: if there is internet access, all is great. If there is no internet, you are royally fu**ed…

How about URI-encoding the password?

It seems that URI encoding replaces the special characters with %{ascii hex} - I tried that already

Hmmm… If your company’s proxy server authenticates with non basic auth, you might have to put cntlm between curl and the proxy.

OK, I think I managed to do it, after all:

  1. I had to build and use cntlm server
  2. Had to set the following 4 env. vars: HTTP_PROXY, HTTPS_PROXY, http_proxy, https_proxy. There are so many utilities that use internet during the build, some use one variable, some another. And on linux the case of env. var. matters
