I focused on ffmpeg because that's a requirement for MakeMKV which I now intend to use as a first PoC for the new userland. Before proceeding there, doing test builds now on all supported architectures and FreeBSD versions, so I'll have to wait quite a while ;) The new Linux ffmpeg port has almost everything enabled that's in the default options of the FreeBSD ffmpeg port. I just left out very few things that seemed *too* complex right now, like e.g. Vulkan. To get there, I created a total of 150 ports now. Still, test-building this ffmpeg "only" wants to build 124 ports, probably because of Xorg libraries, once I noticed I need them, I created ports for *all* of them. A selection of what I added: * Languages: TCL, Python, Perl * Build systems: autoreconf, cmake, meson, ninja (all usable with their standard USES, my new USES adjusts what's needed to do Linux builds) * Lots of "codec" libs: lame, opus, ogg/vorbis, vpx, x264, x265, ... * Infrastructure libs like libdrm, libglvnd, alsa, v4l, ... A first takeaway could be that indeed, this will be kind of yet another Linux distribution, as mentioned in sceptical responses so far. I still hope it will be possible to limit the scope, we'd only need ports providing shared libraries that (closed-source or otherwise not portable) Linux software would need to run in Linuxulator. That said, there's probably still a lot missing, like e.g mesa-dri (for games and similar), gtk3/gtk4/qt5 (for GUI apps that aren't statically linked), and so on. On the plus side, a lot of ports could be created by just copying the original port and doing adjustments, and most of the time, the result was simpler than the original (e.g. almost all patches could be dropped). I also removed all port options, still unsure whether they *might* make sense later, but for a first PoC, they just add unnecessary complexity. There were almost no surprising build issues so far (so, I guess accidentally pulling in things from FreeBSD base really isn't a thing, at least not when building in poudriere), except for one: It seems a "relative" rpath (using $ORIGIN) doesn't work. To work around this with one port using that during build, I had to add some explicit LD_LIBRARY_PATH.
