Building Git using just a\nmake command can work.\n\nYou might want to try it and see if it fails as you expect when\nlibcurl4-gnutls-dev is not installed.\n\nIn the top level Makefile you can see all the variables that can be\nset to customize the build.\n\nThese days the configure infrastructure is not as well maintained as\nthe Makefile.\n\nBest,\nChristian.\n"},{"id":"391738","messageId":"20200214061714.GA605125@coredump.intra.peff.net","threadId":"52792","inReplyTo":"A0910AA2-D24B-4DF5-8D39-8E2D8B56955B@gmail.com","subject":"Re: How to force configure script to use curl ?","fromName":"Jeff King","fromEmail":"peff@peff.net","sentAt":"2020-02-14T06:17:14Z","receivedAt":"2020-02-14T06:17:17Z","isPatch":false,"sender":{"key":"peff@peff.net","avatar":"https://avatars.githubusercontent.com/u/45925?v=4"},"body":"On Wed, Feb 12, 2020 at 05:08:06PM -0500, Philippe Blain wrote:\n\n> Is there a way to force the configure script to error out if it does\n> not find curl (or any one of the optional dependencies that I happen\n> to need for my build?)\n\nI don't think so.
