I grabbed a V4L CVS today and tried to compile it. It gives me a compiling error. Anyone else trying to compile a pull from v4l CVS?

Here's the compile error. Any suggestions?

You should check with the V4L devs to see what they say. Looks like they've missed/mistyped some things, or there are dependencies that you don't have fulfilled on your system.

This patch fixed the compiling problem. It was the recent changes for videodev split up.

v4l cvs now compiles...

I was hoping for a little help on this. I tried using the patch but get these errors:




Probably because I don't really know what I'm doing with this. I ran it on driver source, is that correct? I have been trying to get this thing updated forever and am not getting any further. Any help would be much appreciated. I need to get the v4l compiled as who knows when a new kernel will be introduced into KM. Thanks

What does this patch do? Where can I find details?

The patch is supposed to allow an install of newer v4l-dvb drivers on the 2.6.18. It originated here:

LOL! KnoppMyth R5F27 at the time of it's release had newer versions of the drivers. Newer than what was in the kernel. You don't need this patch, the work has been done for you.

I don't get the joke. I am trying to install the "tip" as are the rest of the folks in this thread. R5F27 isn't more recent than that. I need some mods that are not included on my R5F27.

Is the patch not up to the "tip"? I have been able to fix almost every issue ever encountered with KM by using this forum without needing to ask too many questions. But installing the V4L-DVB "tip" or any other version just doesn't seem resolved for me with any posts here. This seemed to be the most promising of late after kernel sources, kernel links, etc.

Just seems from all the errors there is an issue with .../videodev.c:* in 2.6.18 for several people on the make and some people used this patch to get over the hump. Is there a better way to get this to work?

I started a post some time ago but never had a resolution then either. Sucks since my KM box is just sitting there waiting for a fix.

You shouldn't need a patch to compile tip. Would you like to test the latest version of Knoppmyth to ensure it resolves your problem? If so, please PM me.

I posted some patches to the dvb/v4l hg tree. I wanted to test out my patches and need this patch to be able to compile the hg tree.

The hg tree gets updated on a daily basis?

Dwaine

Would you like to test the latest version of KnoppMyth? It is based on 2.6.23 and a very recent V4L/DVB "tip".

arrrgghhh.. I can get the v4l-dvb HG tree to compile, but it does not compile all the modules in the tree.

I did do a make kernel-links. make all

There is suppose to be 228 modules that get compiled. Guess what.. The two modules the saa7134 and cx88 is what I needed. Anyway around this.

I was hoping to get this resolved this weekend so I can submit the necessary patches to get the Digiwave 108g card working under v4l-dvb. Just need to test out the patches on my mythtv box.

Dwaine

I can't get the latest dvb drivers to compile either. Dying to put my HVR-1800 to work. I would love to test the latest release for ya, Cecil!

I was trying to update to either trunk or 0.21-fixes but the compile failed when trying to do mythplugins. It referenced videodev.h which is a symbolic link to an install that sat in the root folder before R5F27 was cleaned up and released. Where can I get the headers I need or do I need to re-download v4l-dvb?

Hello,

The same applies to Satelco Easywatch PCI DVB-T card. The card does not work out of the box under Knoppmyth R5F27. This patch may solve it. As trying to compile latest v4l-dvb drivers against 2.6.18-chw-13 kernel (KnoppMyth R5F27), I am facing the very same issue:



Definitely yes , as attempts to compile present v4l-dvb drivers with kernel older than 2.6.19 seem to be unsuccessful.

Regards.
