Hi all, 1. the luatex binary for linux armhf is too old for the recent version of ConTeXt. It is a 1.0.3 from March 2017. 2. first problem would be not a so big one, but since development level 6505 I'm not able to compile the experimental luatex myself anymore. It compiles luajittex but not luatex. My call to build.sh is: sh ./build.sh --jit --parallel 1>compile.log 2>error.log I append the error.log. 3. In first-setup.sh is an entry for armv7l. On my system, "uname -m" shows armv8l. After every download of the script, I have to edit it. If someone adds a section for armv8l, I could use the original first-setup.sh without changing armv7l to armv8l. Greetings Lutz -- GPG Key ID 3C4F83BC
