Failed to build gem native extension

[Donatien]

Hello, please forgive me in advance if I'm doing a mistake as I'm quite new to using vim. I'm trying to install sqlint on windows 10. Installation on Fedora 23 on another machine worked fine but I can't install on Windows 10 for use with gvim 7.4.17.

I installed ruby and the ruby dev environment, as required. As far as I understood, the issue lies with this part of the file "extconf.rb" (located here for me: C:\Ruby23-x64\lib\ruby\gems\2.3.0\gems\pg_query-0.9.0\ext\pg_query):
unless File.exist?("#{workdir}/libpg_query.tar.gz") File.open("#{workdir}/libpg_query.tar.gz", 'wb') do |target_file| open('https://codeload.github.com/lfittl/libpg_query/tar.gz/' + LIB_PG_QUERY_TAG, 'rb') do |read_file| target_file.write(read_file.read) end end end

I can successfully download the tar.gz file manually (recreating the url with LIB_PG_QUERY_TAG = '9.5-1.1.0'). But when I run "gem install sqlint", I get the following error message and this repository (C:\Ruby23-x64\lib\ruby\gems\2.3.0\gems\pg_query-0.9.0\ext\pg_query) contains an empty file ((libpg_query.tar.gz => 0KB).

The last double-dashed line (beginning with ruby=C:/...) contains what looks like an error related to a certificate: state=SSLv3 read server certificate B: certificate verify failed (OpenSSL::SSL::SSLError)
Is there a link with the fact SSLv3 is now considered insecure and generally blocked ?

I hope it's not a bad setup on my side that I would not be aware of and that I'm not simply make you lose your time...

Thanks guys, Donatien

Sorry, not sure. I don't have a Windows machine. After a little Googling, it looks like an issue with Rubygems and your local certificate store. There's a chance this might help: https://gist.github.com/luislavena/f064211759ee0f806c88

@lakshmanavula As the message says, this is the pg_query gem failing to install: it's a dependency of sqlint. Take a look at the build output file, the path to which was printed in the above messages, and if that doesn't give you a clue, you can check with the pg_query authors.
