What to do after MPV-Build on Linux

[anesuc]

Hi,

This is slightly linked to my previous issue #67 I added a while back but there hasn't been any response to it. So I've tried to see if I can attempt it either way but I am not sure where to go from here. This is related to this:

Compile static libmpv.so with e.g. mpv-build.

I've compiled with mpv build as instructed on that git. But I don't really know where to go from here. How do I link to this newly compiled one?

Hopefully someone has a solution to this as a project of mine is on standstill due to this sadly.

Thanks

Update: I've added the .a files for libav I've compiled into the "libraries" binding.gyp and it compiled fully. However I'm now getting undefined symbols errors i.e:

undefined symbol: mpv_create

When I try to run the App

Probably you forgot to enable libmpv.

[anesuc]

What do you mean? --enable-libmpv-shared? That just generates the .so one which I can't use because it's a non static one. Either way I did that and included the same .a files still same error. I'll retry in a sec it in case I missed something

[Kagami]

Try with --libmpv-static

This is into the mpv_options file right? Because I did that and got this error:
`make: Leaving directory '/node_modules/mpv.js/mpv-build/ffmpeg_build'
Using mpv options: --libmpv-static
waf [commands] [options]

Main commands (example: ./waf build -j4)
.....(Shows a lot of options I can use here)
.....
waf: error: no such option: --libmpv-static`

One of the options in there just had enable infront of it which was:
--enable-libmpv-static
Did that and it compiled successfully. However, still same problem :(

[anesuc]

Wait, I think I know

[anesuc]

I didn't have the newly created libmpv.a in binding.gyp but after adding it I get errors during buld now which are:

Edit: I'm looking into the fPIC flag

[anesuc]

Looked into the fPIC flag which is not a valid flag for mpv_options. The closest was --enable-pic which looked like it was already enabled for ffmpeg_options but I added it anyway. It's not valid for mpv_options though.

Any ideas?

[anesuc]

Update on this tried adding --enable-static-build as well ended up with this error during compile of mpv:

`scripting.c:302: warning: Using 'dlopen' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
/usr/bin/ld: cannot find -ldrm
collect2: error: ld returned 1 exit status

[Kagami]

You can ask in https://github.com/mpv-player/mpv how to compile static libmpv.

[anesuc]

Ok I've asked the question there! Hopefully we might get somewhere! Was documenting here so that it might help someone attempting this later

Can you tell me how to compile libmpv for linux x64 and arm64, I can’t run it after compiling
