Build failure with GCC 8? (Fedora 28)

Post by hobbes1069 » Sat May 12, 2018 12:20 pm

Had it building fine on Fedora 27 w/ GCC 7 but now I get this:

Code: Select all

libffabi/src/ffabi.c: In function 'ffm_audio_encode_init':
libffabi/src/ffabi.c:520:30: error: 'CODEC_FLAG_GLOBAL_HEADER' undeclared (first use in this function); did you mean 'AV_CODEC_FLAG_GLOBAL_HEADER'?
         ctx->avctx->flags |= CODEC_FLAG_GLOBAL_HEADER;
                              ^~~~~~~~~~~~~~~~~~~~~~~~
                              AV_CODEC_FLAG_GLOBAL_HEADER
libffabi/src/ffabi.c:520:30: note: each undeclared identifier is reported only once for each function it appears in
libffabi/src/ffabi.c: In function 'ffm_audio_encode_get_info':
libffabi/src/ffabi.c:721:28: error: 'CODEC_FLAG_GLOBAL_HEADER' undeclared (first use in this function); did you mean 'AV_CODEC_FLAG_GLOBAL_HEADER'?
     if ((ctx->avctx->flags&CODEC_FLAG_GLOBAL_HEADER)!=0)
                            ^~~~~~~~~~~~~~~~~~~~~~~~
                            AV_CODEC_FLAG_GLOBAL_HEADER
Thanks,
Richard

The problem isn't GCC, it's that libavformat just updated and a variable name changed. Here's a diff:

Apply that and it should compile okay.

The patch allows it to compile, but I get an error "Application failed to initialize" when I try and launch it.

I reinstalled Fedora 28 from scratch. That helped a lot. The series of upgrades left a bunch of cruft that made compiles not work correctly. (Like ldconfig database containing old information that no longer existed.)

This looks to be due to an upgrade to ffmpeg 4.0, which versions it's libraries as .58. Fedora 27 was on ffmpeg 3.3, which is .57. Unfortunately there is only a compat library for ffmpeg 2.8, which is .56.*

Not sure there is a simple workaround here until a new makemkv-bin with makemkvconv linked against the new library is released or a compat-ffmpeg33 package is added to the repo. I may just build my own if I have to. :)

* I'm using the rpmfusion repo. Not sure if there are any alternate repos worth using these days.

The diff from chowbok worked for me on Debian Unstable.

This worked for me on Fedora 28, thanks.
