Building OCIO on Windows using MS Visual Studio 2022
Manual steps for installing pre-requisites
- Install Microsoft Visual Studio
- Install Python
- Install CMake
- Install Doxygen (optional: only for python documentations)
Microsoft Visual Studio (Desktop development with C++)
Please use the official Microsoft Visual Studio installer.
Python
Please use the official Python installer
Make sure to check the option to add Python to PATH environment variable while running the installer
Cmake
Please use the official CMake installer.
See https://cmake.org/download/
Example: https://github.com/Kitware/CMake/releases/download/v3.23.1/cmake-3.23.1-windows-x86_64.msi
Make sure to check the option to add CMake to PATH environment variable while running the installer
Doxygen (optional: for editing the documentation)
Please use the official Doxygen installer.
See https://www.doxygen.nl/download.html
Example: https://www.doxygen.nl/files/doxygen-1.9.3-setup.exe
Running the script to install the remaining pre-requisites
Using ocio_deps.bat
ocio_deps.bat script can be used to verify and install the rest of OCIO dependencies.
The script can be used to install the following:
- Vcpkg
- OpenImageIO
- FreeGLUT
- Glew
- Python documentation dependencies (six, testresources, recommonmark, sphinx-press-theme, sphinx-tabs, and breathe)
Run ocio script and follow the steps.
ocio_deps.bat --vcpkg <path to vcpkg root>
See ocio_deps --help:
Mandatory option:
--vcpkg path to an existing vcpkg installation or path where you want to install vcpkg
Running the script to build and install OCIO
Using ocio.bat
Ocio.bat can be used to build and install OCIO.
# Options can be removed by modifying the value inside ocio.bat script.
# see the top of ocio.bat file
# Produce a release build using the default build and install paths.
ocio.bat --vcpkg <vcpkg directory> --type Release --ocio <path to OCIO source>
# Produce a debug build using the default build and install paths.
ocio.bat --vcpkg <vcpkg directory> --type Debug --ocio <path to OCIO source>
# Produce a release build using a custom build path (--b) and a custom install paths (--i).
ocio.bat --vcpkg <vcpkg directory> --type Release --b C:\ocio\__build --i C:\ocio\__install --ocio <path to OCIO source>
See ocio --help:
Mandatory options:
--vcpkg path to an existing vcpkg installation
--ocio path to OCIO source code
Optional options depending on the environment:
--python Python installation location
--msvs path where to find vcvars64.bat from Microsoft Visual Studio
Default: C:\Program Files\Microsoft Visual Studio\2022\Enterprise\VC\Auxiliary\Build
--b build location
Default: C:\Users\cfuoco\AppData\Local\Temp\OCIO\build
--i installation location
Default: C:\Users\cfuoco\AppData\Local\Temp\OCIO\install
--type Release or Debug
Default: Release
--configure Run cmake configure or not
Default: false
