iperf3 static builds

Build Platforms

• Alpine linux edge using qemu emulation
• Windows on Github Actions runners for x86_64 using a custom Cywgin installer script
• MacOS on Github Actions runners for amd64 (mmacos-13) and arm64 (macos-14) with static openssl and iperf libraries.

Available architectures

Linux:

• Arch: amd64 arm32v6 arm32v7 arm64v8 i386 ppc64le riscv64 s390x
• Docker: yes
• Static binaries: yes

Windows:

• Arch: amd64
• Docker: no
• Static binaries: yes

MacOS:

• Arch: amd64 arm64
• Docker: no
• Static binaries: yes

Note

Windows and MacOS binaries are not fully static in terms of their dependency and cygwin1.dll (Windows) libSystem.B.dylib (MasOS). They are statically linked with libcrypo.a libssl.a (openssl) and iperf3.a (iperf3) so there should be no other system dependency required to run them on the target hosts.

On Windows openssl is built from Github source to get static libs and on MacOS we get them from the brew cellar installation of openssl@3

Download - Static Binaries

Static binaries for Linux and Windows are available here: https://github.com/userdocs/iperf3-static/releases/latest

Example:

curl -sLo- iperf3 https://github.com/userdocs/iperf3-static/releases/latest/download/iperf3-amd64
chmod +x iperf3
iperf3 --version

Download - Docker

Multiarch Docker images are available via https://github.com/users/userdocs/packages/container/package/iperf3-static

Example:

docker pull ghcr.io/userdocs/iperf3-static:latest

To used the image dynamically

docker run -it ghcr.io/userdocs/iperf3-static:latest iperf3 --version

Generic Build dependencies

Expand for details

apk add build-base pkgconf autoconf automake curl libtool git perl openssl-libs-static openssl-dev linux-headers

Debian linux

apt install -y build-essential pkg-config automake libtool libssl-dev git perl

Cygwin packages

Without openssl

automake,gcc-core,gcc-g++,git,libtool,make,pkg-config

With openssl

automake,gcc-core,gcc-g++,git,libtool,make,pkg-config,libssl-devel,zlib-devel

Generic Build Instructions

Clone the git repo - linux + Cygwin

git clone https://github.com/esnet/iperf.git ~/iperf3 && cd ~/iperf3

Bootstrap - If you cloned the repo

./bootstrap.sh

Configure - linux + Cygwin

Note: Cygwin requires requires compiling openssl and zlib static libs to link statically. Otherwise you compile dynamically

Static

./configure --disable-shared --enable-static-bin --prefix=$HOME

Dynamic

./configure --prefix=$HOME

Cygwin openssl requires compiling openssl and zlib

Build - linux + Cygwin

make -j$(nproc)
make install

Check the linking was done properly

ldd ~/bin/iperf3

Version

Use this command to check the version.

~/bin/iperf3 -v

Will show something like this.

iperf 3.10.1 (cJSON 1.7.13)
Optional features available: CPU affinity setting, IPv6 flow label, TCP congestion algorithm setting, sendfile / zerocopy, socket pacing, authentication, bind to device, support IPv4 don't fragment

Windows builds required being bundled with Cygwin dlls to work so these are not single static binaries. They have a directory structure like this.

iperf3.exe
cygwin1.dll

Windows x64 no openssl
