[linux-dvb] Problem making v4l driver tree

[linux-dvb] Problem making v4l driver tree

[Mike Adolf]

According to the Mythtv Wiki on the pctv 800i card you need to extract
firmware from windows file and download "v4l-dvb-c800683faf86.tar.gz",
and do a make and make install to get the latest tree of drivers
installed.  However, when I did the make I got the following  error.
------
Updating/Creating .config
Preparing to compile for kernel version 2.6.25
File not found: /lib/modules/2.6.25.16-0.1-pae/build/.config at
./scripts/make_kconfig.pl line 32, <IN> line 4.
make[1]: *** No rule to make target `.myconfig', needed by
`config-compat.h'.  Stop.
-----
I am use to resolving dependency errors but don't know what to do with
this one. I am using SuSe 11.   Since I do get good video but no sound,
would it be a good idea to do an 'Install-sound' only-once I get it to make?

Mike,
          the make file is looking for the .config from your installed 
kernel. On some distributions like Gentoo it is where it is expected 
because Gentoo users compile another kernel at the drop of a hat. Other 
distros like ubuntu ship the config file but it is not in the right 
place. For ubuntu you would look in the /boot directory. It will be 
called something like config-<kernel revision>. Copy it to the name 
.config in the specified directory:

/lib/modules/2.6.25.16-0.1-pae/build/.config

You will need to find out what your distro does to ship the config file, 
get a copy and put it there.

Mike,
          I usually find that it failing to find the include files 
indicates that the kernel source/headers are not installed correctly. I 
find that for my distro doing a make kernel-links with perhaps a depmod 
thrown in fixes this kind of problem. I don't know about the IRQ loop 
but then honestly I don't know much about this stuff.

Cheers Paul
