Requirements

For Debian (version 10 “Buster” or later) and Ubuntu (version 18.04 or later):

sudo apt install \
    cmake gcc-arm-linux-gnueabihf libc6-dev-armhf-cross gdb-multiarch \
    python3-pyqt5 python3-construct python3-flask-restful python3-jsonschema \
    python3-mnemonic python3-pil python3-pyelftools python3-requests \
    qemu-user-static tesseract-ocr libtesseract-dev

pip install pytesseract

For optional VNC support, please also install libvncserver-dev:

sudo apt install libvncserver-dev

Build

speculos

cmake -B build/ -S .
make -C build/

Please note that the first build can take some time because a tarball of OpenSSL is downloaded (the integrity of the downloaded tarball is checked) before being built. Further invocations of make skip this step.

The following command line can be used for a debug build:

cmake -B build/ -DCMAKE_BUILD_TYPE=Debug -S .

VNC support (optional)

Pass the WITH_VNC option to CMake:

cmake -B build/ -DWITH_VNC=1 -S .
