How to Build:


  • git clone
  • cd mfgtools
  • git submodule init
  • git submodule update
  • open msvs/uuu.sln with Visual Studio 2017

Visual Studio

Note that, since uuu is an OSI compliant Open Source project, you are entitled to download and use the freely available Visual Studio Community Edition to build, run or develop for uuu. As per the Visual Studio Community Edition license this applies regardless of whether you are an individual or a corporate user.


  • git clone
  • cd mfgtools
  • sudo apt-get install libusb-1.0-0-dev libbz2-dev pkg-config cmake libssl-dev g++
  • cmake . && make

The above commands build mfgtools in source. To build it out of source (requires cmake 3.13 or newer): -

cmake -S . -B build
cmake --build build --target all

For cmake prior 3.13: -

mkdir build && cd build
cmake .. && make


  • git clone
  • cd mfgtools
  • brew install cmake libusb openssl pkg-config
  • cmake -DOPENSSL_ROOT_DIR=$(brew --prefix)/opt/openssl . && make

Note that we assume brew is installed and can be used to resolve dependencies as shown above. The remaining dependency

can be resolved via the XCode supplied libraries.

Run environment

  • Windows 10 64 bit
  • Linux (Ubuntu) 64 bit
  • macOS (Catalina)
  • 32 bit systems will have problems with big files.
