Hello Jan, > I had a success building ffmpeg-jami on both aarch64-linux and > armhf-linux (through qemu). I have one question regarding the naming > convention of variables. Why do some variables start with "%"? I > couldn't find any explanation in the documentation nor in the source > code. Say I want to add a variable called > "ffmpeg-linux-configure-flags". Should I start it with "%" - > "%fmpeg-linux-configure-flags" or not? Good job! Variables prefixed by '%' often denote parameters (see: https://www.gnu.org/software/guile/manual/html_node/Parameters.html). I guess something like: --8<---------------cut here---------------start------------->8--- (define %fmpeg-linux-configure-flags '("--flag-1" "--flag-2")) --8<---------------cut here---------------end--------------->8--- would be fine. But using "ffmpeg-linux-configure-flags" would also be correct. Thanks, Mathieu
