ubuntu linux 18.04(arm64)でblender v2.92のビルドメモ

以下を変更。

CMakeLists.txt
WITH_CYCLES_EMBREE OFF
※使いたい場合はhttps://developer.blender.org/D9505を参考にembree-aarch64を入れる

/blender/build_files/build_environment/install_deps.sh:2069（USE_SIMD=sse2）行目をコメントアウト

./blender/build_files/build_environment/install_deps.sh:2337（USE_SIMD=sse2）行目をコメントアウト

install_deps.shの実行前にOPENEXR_ROOTを定義。
export OPENEXR_ROOT=/opt/lib/openexr
（./blender-deps/OpenImageIO-2.1.15.0/src/cmake/modules/FindOpenEXR.cmakeのバグ？）

そしてこれがビルドスクリプト

#!/bin/sh

apt update
apt install -y sudo ###

apt install -y gcc g++ make cmake
apt install -y git subversion
apt install -y libx11-dev libxxf86vm-dev libxcursor-dev libxi-dev libxrandr-dev libxinerama-dev libglew-dev

cd cmake-3.19.0
./bootstrap && make

mkdir ~/blender-git
cd ~/blender-git
git clone https://git.blender.org/blender.git

export OPENEXR_ROOT=/opt/lib/openexr ### Because of BUG of./blender-deps/OpenImageIO-2.1.15.0/src/cmake/modules/FindOpenEXR.cmake

PATH=~/cmake-3.19.0/bin:$PATH ./blender/build_files/build_environment/install_deps.sh -t 4 --no-confirm --with-opencollada

cd ~/blender-git/blender
make update
make

下はchrootしてビルドしたバイナリのときの実行コマンド(jetson nanoで確認)

# This is when chroot build.

VirtualGLから起動するときのスクリプト
（blender_291_vgl.shは上のコマンドの実行）

#!/bin/sh

/opt/VirtualGL/bin/vglconnect -e ./blender_291_vgl.sh <host>

※cd blender292-build; ./blender.shで起動
