Build

Branch	Status
main
release/10.1
release/10.2

Requirements

• Visual Studio
  • From 2017 to 2022
  • English only (vcpkg limitation)
  • Use this installer configuration or alternatively use vstools
  • Check also "Desktop development with C++"
• Kitware's CMake >= 3.25 or Visual Studio integrated version

Build environment can be setup quickly using Microsoft's developer virtual machines. Import this .vsconfig from Visual Studio Installer.

Commands

Both 32-bit and 64-bit versions should be built for maximum compatiliby before deployment. See https://dfir-orc.github.io for more details about deployment and configuration.

In a prompt like Developer Command Prompt for VS 2019 (prefer to avoid using cmd.exe):

git clone --recursive https://github.com/dfir-orc/dfir-orc.git
cd dfir-orc
mkdir build-x86 build-x64

cd build-x86
cmake -G "Visual Studio 17 2022" -A Win32 -T v141_xp ..
cmake --build . --config MinSizeRel -- -maxcpucount

cd ../build-x64
cmake -G "Visual Studio 17 2022" -A x64 -T v141_xp ..
cmake --build . --config MinSizeRel -- -maxcpucount

• The -T v141_xp option will allow compatibility with Windows XP SP2 and later, it can safely be removed if this is not required.

• The default ORC_BUILD_VCPKG=ON option will build vcpkg packages in 'external/vcpkg' subdirectory.

Important Always do a git submodule update after any git pull to update submodules aswell. Alternatively, always pull with git pull --recurse-submodules
