 |
|
I'm having some problems emerging MythTV. I'm using a 2.6.9 kernel with dvb support compiled in.
Emerging mythtv-0.16 crashes with
| Code: | <snip>
In file included from dvbchannel.h:20,
from videosource.h:14,
from videosource.cpp:1:
dvbtypes.h:18:31: linux/dvb/version.h: No such file or directory
dvbtypes.h:20:2: #error "DVB driver includes with API version 3 not found!"
dvbtypes.h:23:32: linux/dvb/frontend.h: No such file or directory
dvbtypes.h:24:27: linux/dvb/dmx.h: No such file or directory
In file included from dvbchannel.h:20,
from videosource.h:14,
from videosource.cpp:1:
</snip> |
I have media-tv/linuxtv-dvb-1.1.1 installing (I know its not needed with a 2.6 kernel), however if I try to emerge media-libs/libdvb-0.5.0-r1 I get errors such as:
| Code: | <snip>
ci.cc:34:26: linux/dvb/ca.h: No such file or directory
ci.cc: In member function `bool cCiTransportLayer::ResetSlot(int)':
ci.cc:571: error: `CA_RESET' undeclared (first use this function)
ci.cc:571: error: (Each undeclared identifier is reported only once for each
function it appears in.)
<snip> |
Does anyone have any ideas? I'm not sure if these two problems are related.(I tried to install libdvb to solve the mythtv problem)
Thanks! |

hrm...
i'm hacking on this too... saw some other people with similer problems, and i just hacked mine up, and it built libdvb for me error free... I have no idea if its functional, but here's what i did.
| Code: | mkdir /usr/include/linux/dvb && cp /usr/src/linux/include/linux/dvb/* /usr/include/linux/dvb/
|
and that took... i'm running off of a 2.6.9-nitro3 ATM, if it makes any difference...
now, someone tell me what horrible things will happen to my box now, I mean, is this going to bring the seven horsemen, or anything? 
EDIT:cross fingers, mythtv made it past its previous crash and burn, and is contiinuning on unopposed...
EDITEDIT: AGGG! spoke too soon... now its failing somewhere up in dvbchannel.cpp and dvbdiseqc.cpp... *investigates*
EDITEDITEDIT: https://forums.gentoo.org/viewtopic.php?t=224772 fix applied... billion and one warnings through the dvbs, but still going so far... |

It seems like the ebuild is looking for ca.h in /usr/include/linux/dvb/ when it's actually in /usr/src/linux/include/linux/dvb/!
Same problem here: libdvb, a required package for mythtv, fails on a "missing" ca.h:

!!! If you need support, post the topmost build error, NOT this status message. |
I tried SPY_jmr1's little trick of simply copying the files into the expected location, but the emerge then ran into several all-new errors.
How can I tell the build to look in the right place for these files??
Incidentally, earlier I had the same trouble that other people were reporting with emerging linuxtv-dvb on a 2.6 kernel, but it emerged fine after a simple:
| Code: | | echo media-tv/linuxtv-dvb ~x86 >> /etc/portage/package.keywords |
(The version that failed was 1.0.1. The ~x86 one that worked is 1.1.1-r1.) |

Ahhhh, a solution!! On 2.6 kernel machines:
| Code: | emerge -C linux-headers
emerge linux26-headers |
This puts the necessary files into /usr/include/linux/dvb/. Then a simple:
and libdvb comes out sweet as you please!
Not only that, but mythtv-0.16 then happily compiles with the 'dvb' USE flag.
I'll report this on that bug. |
