Blender 2.90 Local build fails

Building Blender

Updates:

  • I managed to install both gcc-8 and gcc-9 (on Ubuntu 18.04). The key was to install gcc-9 first and gcc-8 after that. CUDA requires gcc-8 and fails with a different version, but Blender now requires a different version.

  • The build went better, but it still fails. Now with a different error!

It seems to be related to OpenMP. I installed libomp-dev in course of previous clang attempts, but now I will try once again without it.

UPDATE I can happily report that the compilation works now. Here is the script assuming 18.04 with CUDA already installed:

sudo apt-get -qq update && sudo add-apt-repository -y ppa:ubuntu-toolchain-r/test
sudo apt-get -qq update && sudo apt-get install -y build-essential git subversion cmake libx11-dev libxxf86vm-dev libxcursor-dev libxi-dev libxrandr-dev libxinerama-dev libglew-dev gcc-9 g++-9 software-properties-common && sudo apt autoremove -y

git clone https://git.blender.org/blender.git

mkdir -p lib && cd lib && svn checkout --quiet https://svn.blender.org/svnroot/bf-blender/trunk/lib/linux_centos7_x86_64

sudo apt install -y gcc-8 g++-8
ln -sf /usr/bin/gcc-8 /usr/local/cuda/bin/gcc && ln -sf /usr/bin/g++-8 /usr/local/cuda/bin/g++

cd blender && make update

CC=gcc-9 CXX=g++-9 make #with whatever arguments
