How to build QEMU ESP32 for Windows

QEMU ESP32 is a fork of QEMU with Espressif patches for emulating ESP32 microcontroller series. Normally there is prebuilt files in Releases tab, but for some reasons if you want to (or have to) build yourself, then you can follow this guide.

I would recommend Windows environment with MSYS2 for building this. This guide aims at building for x64 architecture, but probably you can do the same for x86 by replacing x86_64 packages with x86 ones.

Step 1: Install MSYS2.
Step 2: Open MSYS2 MINGW64 prompts.
Step 3: Install required packages

pacman -Sy mingw-w64-x86_64-toolchain mingw-w64-x86_64-glib2 mingw-w64-x86_64-dtc mingw-w64-x86_64-pixman mingw-w64-x86_64-ninja mingw-w64-x86_64-meson mingw-w64-x86_64-libgcrypt mingw-w64-x86_64-SDL2 git diffutils

Step 4: Clone the source code

git clone https://github.com/espressif/qemu --depth=1 -b esp-develop --single-branch
cd qemu

Step 5: Configure

mkdir qemu-esp32-windows-x86_64
./configure --target-list=xtensa-softmmu \
    --enable-gcrypt \
    --enable-slirp \
    --enable-sdl \
    --disable-strip --disable-user \
    --disable-capstone --disable-vnc \
    --disable-gtk \
    --prefix=$PWD/qemu-esp32-windows-x86_64

Step 6: Build

ninja -C build

Step 7: Install

ninja -C build install

Your built files will be in qemu-esp32-windows-x86_64 directory. Remember that for a standalone version, you need to copy some required DLLs (usually from C:\msys64\mingw64\bin)
