I need to install libx264 for ffmpeg because a minecraft mod (ReplayMod) I’m using for recording some gameplay sessions requires me to have it in order to render the recordings. So, I asked for help in the mod’s Discord server & someone suggested I use this which are instructions for MacOS.
But, the ./configure --disable-asm --enable-static part doesn’t seem to work on Endless, so how can install it, what should I edit in the command, please help 
♂.
I’ll upload he diagnostic file just in case.
