[![Travis-CI Build Status](https://api.travis-ci.org/moparisthebest/static-curl.svg?branch=master)](https://travis-ci.org/moparisthebest/static-curl)
These are a couple simple scripts to build a fully static curl binary using an alpine linux docker container. Currently it is a minimal build with OpenSSL and only supporting HTTP and FTP. Tweak configure options in [build.sh](build.sh#L33) if you need something else (and/or suggest or PR).
Grab the latest release (curl 7.67.0) from one of these links, by CPU architecture:
- [curl-amd64](https://github.com/moparisthebest/static-curl/releases/download/v7.67.0/curl-amd64)
- [curl-i386](https://github.com/moparisthebest/static-curl/releases/download/v7.67.0/curl-i386)
- [curl-aarch64](https://github.com/moparisthebest/static-curl/releases/download/v7.67.0/curl-aarch64)
Development
-----------
File explanation:
- [build.sh](build.sh) - runs inside an alpine docker container, downloads curl, verifies it with gpg, and builds it
- [docker_build.sh](docker_build.sh) - runs build.sh inside docker
- [mykey.asc](mykey.asc) - Daniel Stenberg's [GPG key](https://daniel.haxx.se/address.html) used for signing/verifying curl releases
- [bicep curl](https://thenounproject.com/term/curl/499187) by Laymik from [the Noun Project](https://thenounproject.com)
