Preparing Open RV on Rocky 8 and 9

Open RV 2025 can be built for Rocky 8 and Rocky 9, using the VFX reference platform. Dependencies can be viewed in the cmake/defaults/ folder. eg cmake/defaults/CY2026.cmake, with only minor differences for the config manager repo and the requirement for Perl-CPAN.

Select your VFX reference platform by clicking on the appropriate tab. Install instructions follows.

Python              : 3.13.9
Qt                  : 6.8.3 ** RV Still on 6.5.3 pending work

Config manager repo : powertools  (Rocky 8)
Config manager repo : crb         (Rocky 9)
Perl-CPAN           : 2.36+       (Rocky 9)

All other dependencies are shared across variations.

  1. Install tools and build dependencies

  2. Install Pyenv / Python

  3. Install CMake

  4. Install Rust

  5. Install Qt

  6. Build Open RV

  7. Building with Docker (Optional)

1. Install tools and build dependencies

1.1. Set the config manager

sudo dnf config-manager --set-enabled powertools devel

1.2. Install other dependencies

sudo dnf install wget git epel-release

sudo dnf groupinstall "Development Tools" -y

sudo dnf install -y alsa-lib-devel autoconf automake avahi-compat-libdns_sd-devel bison bzip2-devel cmake-gui curl-devel flex gcc gcc-c++ git libXcomposite libXi-devel libaio-devel libffi-devel nasm ncurses-devel nss libtool libxkbcommon libXcomposite libXdamage libXrandr libXtst libXcursor mesa-libOSMesa mesa-libOSMesa-devel meson openssl-devel patch pulseaudio-libs pulseaudio-libs-glib2 ocl-icd ocl-icd-devel opencl-headers qt5-qtbase-devel readline-devel sqlite-devel systemd-devel tcl-devel tcsh tk-devel yasm zip zlib-devel wget patchelf pcsc-lite libxkbfile perl-IPC-Cmd

sudo dnf install -y xz-devel mesa-libGLU mesa-libGLU-devel

sudo dnf clean all

1.4. Disable the devel repo afterwards since dnf will warn about it

sudo dnf config-manager --set-disabled devel

2. Install Pyenv and Python

Install pyenv to be able to install the specific version of python associated the VFX reference platform

2.1 Install Pyenv

Install pyenv, and add its installation path to your ~/.bashrc and apply the changes to your current terminal window:

curl https://pyenv.run | bash
echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc
source ~/.bashrc

2.2 Install the Python version associated with the VFX reference platform

pyenv install 3.11.8
pyenv global 3.11.8

3. Install CMake

Since the dnf-installable version is not quite recent enough, you’ll need to build and install CMake from source.

wget https://github.com/Kitware/CMake/releases/download/v3.31.6/cmake-3.31.6.tar.gz
tar -zxvf cmake-3.31.6.tar.gz
cd cmake-3.31.6
./bootstrap --parallel=32  # 32 or whatever your machine allows
make -j 32  # 32 or whatever your machine allows
sudo make install

cmake --version  # confirm the version of your newly installed version of CMake
cmake version 3.31.6

4. Install Rust

Warning

Rust version 1.92 or later is required to build certain Python dependencies (such as cryptography).

Install Rust using rustup, and add its installation path to your ~/.bashrc and apply the changes to your current terminal window:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y
echo 'export PATH="$HOME/.cargo/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

Verify that Rust is installed correctly:

rustc --version
cargo --version

5. Install Qt

Download the latest open-source Qt installer. We do not recommend that you install Qt from other installable sources as it may introduce build issues.

- Start the Qt installer
- Installation path: ~/Qt
- Click "Archive" in the hard-to-find dropbown box in the top right side of the window
- Select Qt 6.5.3
# Any 6.5.3+ should work, but Autodesk's RV is build against 6.5.3

Note 1: If you install Qt at a different installation path, you will need to manually export the environment variable “QT_HOME” to that path in your ~/.bashrc file such that the build scripts will be able to find it.

Note 2: Qt modules for Logs, Android, iOS and WebAssembly are not required to build Open RV.

6. Build Open RV

Once the platform-specific installation process is complete, building Open RV follows the same process for all platforms. Please refer to the Common Build Instructions for the complete build process.

7. Building with Docker (Optional)

To build Open RV using Docker, use the provided Dockerfile found in this repository, which should already contain all required dependencies.

Please go through the cloning procedure found in the common build process. Once cloned, get back here to build the docker image, run the container, and build Open RV within the docker container.

7.1. Build the image and run

cd dockerfiles
docker build -t openrv-rocky9 -f Dockerfile.Linux-Rocky9 .
docker run -d openrv-rocky9 /bin/bash -c "sleep infinity"

7.2. Create and run the container

# Lookup the container id for openrv-rocky{8/9}
docker container ls

# It will produce an output that looks like this:
# CONTAINER ID   IMAGE               COMMAND                  {and more}
# 1f6a1104a1f4   openrv-rocky{8/9}   "/bin/bash -c 'sleep…"   {and more}

# Use the "CONTAINER ID" value (1f6a1104a1f4 in this example) in the following command:
docker container exec -it <id> /bin/bash  # replace 'id' with your value

7.3. Build Open RV in the container

Once you are into the container, you can follow the common build process to build Open RV.

7.4. Copy the stage folder outside of the container

If you are on a host that is the same as, or compatible with, your version of Rocky Linux, you can copy the stage folder outside of the container and execute Open RV.

# Container id is the same as the one used in the step above
docker cp <container id>:/home/rv/OpenRV/_build/stage ./openrv_stage
