AviSynth+ 3.5: Linux, macOS, and BSD support

[qyot27]

AviSynth+ version 3.5 marks the first release with native support for non-Windows OSes.

For the past few weeks, this has been getting tested and polished over at the Github repo. There's a few lingering issues that will have to wait for 3.5.1, but the important part is that the AviSynth+ core can now be built and used natively on Linux, macOS, and BSD. As of right now, the only source filter that can be used is FFMS2's C++ plugin.

Tested platforms:
Ubuntu 19.10
macOS 15.3 High Sierra and 15.4 Mojave
FreeBSD 12.1

There is no currently no automatic detection of autoloaded plugins. You'll need to use AddAutoloadDir (on macOS and BSD, AddAutoloadDir currently throws an exception, but LoadPlugin works correctly).

More detailed build instructions can be found in the AviSynth+ documentation.

Nice! This is a major milestone!

[StainlessS]

A big day indeed, thanks very much to all concerned.

[FranceBB]

What an achievement!
For years and years Avisynth has been a Windows only frameserver and people on Linux had to rely on either using AVXSynth (which never got as many things as Avisynth+) or running AVS with wine and just hope. Today is definitely a truly remarkable day which extends the platforms supported and hopefully the Avisynth userbase along with the Doom9 one.

Well done indeed, guys!

I'm gettin' this on build attempt Cinnamon Mint 19.3 Tricia x64.

Is it related to this

There is no currently no automatic detection of autoloaded plugins. You'll need to use AddAutoloadDir (on macOS and BSD, AddAutoloadDir currently throws an exception, but LoadPlugin works correctly).

[qyot27]

The CC/CXX/LD overrides likely need to use 'gcc-9/g++-9' so it sees the correct version of GCC (assuming that you've installed the gcc-9 package). 19.04 and distros based on it are the earliest that can build AviSynth+ with the version of GCC provided in the main repositories, because support for C++17 (to be able to use the filesystem library) was only added in GCC 8.

That warning/error message in sudo apt-get update was from the Google Earth repository, so no, nothing to do with this.

[StainlessS]

What does that mean, I am real new to linux, and never used command line compiler since the 90's.

EDIT: executing

CC=gcc-9 CXX=g++-9 LD=gcc-9

and then

printenv

shows nothing for eg CC, dont know if it should.

EDIT:

I am real new to linux

Well, Pinterf pretty much spoke for me also
[mc pretty much always been the 1st prog I install on linux, since the 90's when I first used RedHat 6.0, I think. (Cinnamon Mint is the first version Linux that has not left me feeling disappointed, though it could still be improved)],

It looks as if that PPA has gcc-9 and g++-9 as separate packages.

sudo apt-get install g++-9

will probably make it work.

A bit further.

EDIT: Actually, we seem to have stopped about the same position as 1st code block in post #5.

EDIT: Just checked DistroWatch, Linux Mint 3rd most page hits for last 6 months period, so solution might assist a lot of users.

[pinterf]

If you are getting that missing <filesystem> error you are still at gcc version less than 8

[StainlessS]

Well no idea what to do about that.
The GNU 7.4 and 9.0 stuff had me confused from the start.
I have to leave home soon, I will probably be on-line, but mobile.

[DJATOM]

Probably CMakeCache related stuff, so delete all contents from build folder and configure again.

[DJATOM]

Tried with my server, looks like my method works (I'm just lazy to search for gcc-9 mirrors for debian buster or build gcc locally, so used gcc-8 on my end)

Many thanks to those involved in making this happen! AviSynth+ installed first time on pop!_os 19.10 (based on Ubuntu 19.10.)

In respect of ffmpeg, which repo is the "Sources" repo mentioned in the instructions? Here's the relevant portion of sources.list.

I know how to uncomment, but I'm not sure which one is meant. Perhaps it's enabled by default.

[pinterf]

I have uncommented all, then did a sudo apt-get update

Thanks. I did the same, and build-dep ffmpeg, nasm, and libsdl2-dev installed fine; but my curiousity as to which repo is envisaged by the instructions remains. (I've only ever edited sources.list to add repos -- never used a graphical interface.)

These variable definitions may only affect the current statement. For them to be persistent, you need to use export (assuming your shell is bash):

export CC=gcc-9 CXX=g++-9 LD=gcc-9
