how to disable module?

[Jean-Baptiste Kempf]

Linux kernel too old.

YOu can force the version at 42

[dm01]

Same problem here.

I need to compile VLC 2.2.0 on Ubuntu 12.04 (Linux 3.2.0-79-generic-pae #115-Ubuntu SMP Thu Mar 12 14:33:25 UTC 2015 i686 i686 i386 GNU/Linux): is it possible?

How to "force the version at 42" ?

Thanks!

[Rémi Denis-Courmont]

You either need to update the kernel headers or VLC. We can't go back in time to fix a bug in an already released version.

../modules/access/dtv/linux.c, 906 row replace on
--------------
#if DVBv5(8)
DTV_STREAM_ID,
#else
DTV_ISDBS_TS_ID,
#endif
(uint32_t)sid);

u can continue compiling.. but may be errors after..

[bat999]

../modules/access/dtv/linux.c, 906 row replace on...

That's too woolly.

I can test your suggestion with 32-bit Ubuntu-12.04 if you edit the file properly.
Otherwise I'll stay with VLC-2.1.6.
