I want to install Pyrender with headless rendering on Ubuntu 14.04. Specifically, I'd like have it installed within a Dockerfile. How can I do it so that OSMesa (and everything else) installs correctly?
Here are the lines from my Dockerfile that got things working (Ubuntu 14.04, python 3.6). It mostly involves following the installation guide, with some extra stuff to make sure deps get installed properly (llvm-6.0
is the main thing that's tricky).
If you're not trying to run in Docker, you can basically just run this stuff (in order) from the command line.
# Install pyrender
RUN pip3 install pyrender
# Copy and rename an apt lib file so that apt-add-repository
# works (cleaner way would be to symlink it but Dockerfiles don't seem
# to like symlinks). Might be due to some screwy python3.6/3.4 conflicts
# on my Docker image
RUN cp /usr/lib/python3/dist-packages/apt_pkg.cpython-34m-x86_64-linux-gnu.so /usr/lib/python3/dist-packages/apt_pkg.cpython-36m-x86_64-linux-gnu.so
# Add new apt repositories and then apt-add some OSMesa deps
RUN add-apt-repository "deb http://apt.llvm.org/trusty/ llvm-toolchain-trusty-6.0 main"
RUN add-apt-repository -y ppa:ubuntu-toolchain-r/test
RUN apt-get update && apt-get install --yes llvm-6.0 freeglut3 freeglut3-dev pkg-config
# Download OSMesa, then build and install it
RUN curl -o mesa-18.3.3.tar.gz ftp://ftp.freedesktop.org/pub/mesa/mesa-18.3.3.tar.gz
RUN tar xfv mesa-18.3.3.tar.gz
