Microsoft has created a Linux subsystem that allows running Linux distributions on Windows 10. This blog describes the steps for building and running wolfSSL on WSL.

Installing WSL and Ubuntu 18.04:

Open PowerShell as Administrator (right-click and choose “Run as Administrator”) Run the following commands: Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux Invoke-WebRequest -Uri https://aka.ms/wsl-ubuntu-1804 -OutFile Ubuntu.appx -UseBasicParsing Add-AppxPackage .\Ubuntu.appx Start -> Ubuntu 18.04 (should be at the top of the start menu) Installing, this may take a few minutes… Choose username and password Update Ubuntu: sudo apt update sudo apt upgrade

Building wolfSSL:

Install prerequisites sudo apt-get install autoconf libtool make execstack git clone https://github.com/wolfSSL/wolfssl.git cd wolfssl ./autogen.sh ./configure make make check

Enabling Intel Speedups and Running Benchmarks:

./configure –enable-intelasm –enable-aesni –enable-sp –enable-sp-asm make WSL does not currently have support for the PROT_GROWSDOWN flag. Manually clear the executable stack flag in the library: execstack -c ./src/.libs/libwolfssl.so ./wolfcrypt/benchmark/benchmark
