The binary is built with GitHub Actions.

Two versions of cURL will be released: one with ECH support (built with OpenSSL's branch feature/ecp) and one without, until OpenSSL's mainline supports ECH.

• curl-linux-ARCH-musl-VERSION: binaries for Linux, linked with musl
• curl-linux-ARCH-glibc-VERSION: binaries for Linux, linked with glibc, these binaries may have compatibility issues in certain system environments
• curl-linux-ARCH-dev-VERSION: binaries, headers and static library archives for Linux, linked with musl(after curl v8.2.1)
• curl-macOS-ARCH-VERSION: binaries for macOS
• curl-macOS-ARCH-dev-VERSION: binaries, headers and static library archives for macOS
• curl-windows-ARCH-VERSION: binaries for Windows
• curl-windows-ARCH-dev-VERSION: binaries, headers and library archives for Windows

For Linux glibc versions, if your system’s /etc/nsswitch.conf file is configured with passwd: compat, glibc will attempt to load libnss_compat.so, libnss_nis.so, libpthread.so, etc. These libraries may not be compatible with the statically linked glibc, and the program might crash.
Currently, there is no good solution for this issue, except for compiling glibc within the script.
In this case, it is recommended to use the musl version.

This script utilizes clang(glibc) and qbt-musl-cross-make(musl) for cross-compilation on Linux, mstorsjo/llvm-mingw for cross-compilation for Windows, providing support for the following architectures:

• Linux
  • x86_64
  • aarch64
  • armv7
  • armv5
  • i686
  • riscv64
  • s390x
  • mips64
  • mips64el
  • mips
  • mipsel
  • powerpc64le
  • powerpc
  • loongarch64
• macOS
  • x86_64
  • aarch64
• Windows
  • x86_64
  • aarch64
  • i686
  • armv7

• To compile locally, install Docker, clone this Git repository, navigate to the repository directory, and then execute the following command:
  sh curl-static-cross.sh
  The script will create a container and compile the host architecture cURL only.

Supported Environment Variables list:
For all VERSION variables, leaving them blank will automatically fetch the latest version.

• ARCHES: The list of architectures to compile. You can set one or multiple architectures from the following options: Compile
• TLS_LIB: The TLS library. Only openssl for now.
• LIBC: The libc. glibc(default) or musl, only affects Linux.
• QBT_MUSL_CROSS_MAKE_VERSION: The version of qbt-musl-cross-make, only affects musl. Check the releases on qbt-musl-cross-make/releases
• CURL_VERSION: The version of cURL. If set to dev, will fetch the latest source code of branch master from GitHub.
• ENABLE_ECH: Enable ECH support in cURL. The default value is false, set to true to enable this feature. Currently released OpenSSL versions do not support ECH. You must use OpenSSL's feature/ech branch; see the OPENSSL_VERSION and OPENSSL_BRANCH settings below. Current releases static-curl do not enable this feature, you have to compile by yourself if you need it.
• OPENSSL_VERSION: The version of OpenSSL. If set to dev, will fetch the branch OPENSSL_BRANCH from GitHub.
• OPENSSL_BRANCH: The branch that fetch from GitHub, this variable will be ignored if OPENSSL_VERSION is not set to dev.
• NGTCP2_VERSION: The version of ngtcp2.
• NGHTTP3_VERSION: The version of nghttp3.
• NGHTTP2_VERSION: The version of nghttp2.
• LIBUNISTRING_VERSION: The version of libunistring.
• LIBIDN2_VERSION: The version of libidn2.
• LIBSSH2_VERSION: The version of libssh2.
• ZLIB_VERSION: The version of zlib.
• BROTLI_VERSION: The version of brotli.
• ZSTD_VERSION: The version of zstd.
• LIBPSL_VERSION: The version of libpsl.
• ARES_VERSION: The version of c-ares.
• TRURL_VERSION: The version of trurl.
• ENABLE_TRURL: Compile trurl. The default value is false, set it to true to enable. NOT available for macOS.
• ENABLE_DEBUG: Enable curl debugging. The default value is false, set it to true to enable. This setting appends --enable-debug to the curl compilation options.

The compiled files will be saved in the current release directory.
