Release files

• curl-linux-ARCH-glibc-VERSION: binaries for Linux, linked with glibc, may be incompatible with some CPUs
• curl-linux-ARCH-musl-VERSION: binaries for Linux, linked with musl
• curl-linux-ARCH-dev-VERSION: binaries, headers and static library archives for Linux, for development, linked with glibc
• curl-macOS-ARCH-VERSION: binaries for macOS

Known issue

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.

Compile

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

• Linux
  • x86_64(glibc and musl)
  • aarch64(glibc and musl)
  • armv7(glibc and musl)
  • armv5(glibc and musl)
  • i686(musl)
  • riscv64(glibc and musl)
  • s390x(glibc and musl)
  • mips64(glibc and musl)
  • mips64el(glibc and musl)
  • mips(musl)
  • mipsel(glibc and musl)
  • powerpc64le(glibc and musl)
  • powerpc(glibc and musl)
• macOS
  • x86_64
  • aarch64
• Windows
  • x86_64
  • aarch64
  • i686
  • armv7

How to compile

Linux

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

• To compile in docker, run:

  docker run --network host --rm -v $(pwd):/mnt -w /mnt \
      --name "build-curl-$(date +%Y%m%d-%H%M)" \
      -e ARCHES="x86_64 aarch64 armv7 armv5 i686 riscv64 s390x mips64 mips64el mips mipsel powerpc64le powerpc" \
      -e TLS_LIB="openssl" \
      -e LIBC="glibc" \
      -e CURL_VERSION="" \
      -e QUICTLS_VERSION="" \
      -e OPENSSL_VERSION="" \
      -e NGTCP2_VERSION="" \
      -e NGHTTP3_VERSION="" \
      -e NGHTTP2_VERSION="" \
      -e ZLIB_VERSION="" \
      -e LIBUNISTRING_VERSION="" \
      -e LIBIDN2_VERSION="" \
      -e LIBPSL_VERSION="" \
      -e ARES_VERSION="" \
      -e ENABLE_TRURL="true" \
      -e TRURL_VERSION="" \
      debian:latest sh curl-static-cross.sh

macOS

Run the following command to compile:

ARCHES="x86_64 arm64" \
    TLS_LIB=openssl \
    CURL_VERSION="" \
    QUICTLS_VERSION="" \
    OPENSSL_VERSION="" \
    NGTCP2_VERSION="" \
    NGHTTP3_VERSION="" \
    NGHTTP2_VERSION="" \
    LIBIDN2_VERSION="" \
    LIBUNISTRING_VERSION="" \
    ZLIB_VERSION="" \
    BROTLI_VERSION="" \
    ZSTD_VERSION="" \
    LIBSSH2_VERSION="" \
    LIBPSL_VERSION="" \
    ARES_VERSION="" \
    bash curl-static-mac.sh

Windows

• To compile locally, install Docker, clone the Git repository, navigate to the repository directory, and then execute the following command:
  ARCHES="x86_64 aarch64" sh curl-static-win.sh
  script will create a Linux container and cross-compile cURL via LLVM MinGW toolchain.

• To compile in docker, run:

  docker run --network host --rm -v $(pwd):/mnt -w /mnt \
      --name "build-curl-$(date +%Y%m%d-%H%M)" \
      -e ARCHES="x86_64 i686 aarch64 armv7" \
      -e TLS_LIB="openssl" \
      -e CURL_VERSION="" \
      -e QUICTLS_VERSION="" \
      -e OPENSSL_VERSION="" \
      -e NGTCP2_VERSION="" \
      -e NGHTTP3_VERSION="" \
      -e NGHTTP2_VERSION="" \
      -e ZLIB_VERSION="" \
      -e LIBUNISTRING_VERSION="" \
      -e LIBIDN2_VERSION="" \
      -e LIBPSL_VERSION="" \
      -e ARES_VERSION="" \
      -e ENABLE_TRURL="true" \
      -e TRURL_VERSION="" \
      mstorsjo/llvm-mingw:latest sh curl-static-win.sh
