What to do after MPV-Build on Linux #68

Open anesuc opened 4 years ago

anesuc commented 4 years ago

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

Kagami commented 4 years ago

Probably you forgot to enable libmpv.

anesuc commented 4 years ago

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

Try with --libmpv-static https://github.com/mpv-player/mpv/blob/82ded968aae9e4141d6b25791546b9f92e3c20d1/wscript#L53

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 :(

Wait, I think I know

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 commented 4 years ago

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 commented 4 years ago

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 commented 4 years ago

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

anesuc commented 4 years ago

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
