Error in installing TBS6985 driver on Linux

[cwjahng]

Hi, my name is Charlie.

I bought a TBS6985 DVB-S2 card and tried to install its driver on a linux PC(CentOS 6.5). But I met a strange error during installation like this:

[root@SAT-CENTOS linux-tbs-drivers]# uname -a
Linux SAT-CENTOS 2.6.32-504.1.3.el6.x86_64 #1 SMP Tue Nov 11 17:57:25 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

Can anybody help me?
I could not find the similar topic in the previous forum. May I miss something?

No. It is useless. It looks different case.

The important error message in my case was:

File not found: /lib/modules/2.6.32-504.1.3.el6.x86_64/build/.config at ./scripts/make_kconfig.pl line 33, <IN> line 4.

but the error message in the proposed posting was different from me:

/usr/src/tbsdrivers/linux-tbs-drivers/v4l/compat.h:26: error: conflicting types for 'find_next_zero_bit'
include/linux/bitops.h:232: note: previous declaration of 'find_next_zero_bit' was here

include/linux/bitops.h:222: note: previous declaration of 'find_next_bit' was here.

Actually, although I followed the advice from the posting by commenting some lines of compat.h, I got the same error messages:

[root@SAT-CENTOS linux-tbs-drivers]# make
make -C /home/admin/TBS/linux-tbs-drivers/v4l

Please help me again~

look in /boot for your current config and copy it to that folder. Honestly though Id be surprised to see it compile. 2.6.32 is quite old (almost 5 years), might be time to upgrade your kernel.

Hi Updatelee,

Thank you for your professional advise.
I tried it as your advise such that I copy /boot config files to /v4l drive and "make" again but got the same results.
I'm a novice for linux so I don't know how old the kernel version is since I just installed "CentOS v6.6" recently. If you say the kernel is so old, I don't know how to do.

Regards,
Charlie.

Centos 7 is the current release

Hi,

Thank you for bob, updatelee and other people who cared this issue.
I tried deeply for days and gave up today.
It looks like a subtle mismatch between version of kernels, subtle relationships of "links", and current update status of some modules. Using the recent version of CenOS 7 was not helpful too. I tried several ways which could be found from google but finally failed.

A very strange thing is, that I tested on an older PC with CentOS 6.5 where I didn't know what history of update it had, and successfully installed TBS6985 driver on it. The symptom was different from mine, and it was the same to what bob posted first, so after I commented on some lines of the file 'compat.h' I could succeed make and make install.

I has been fighting on seeking differences between my CentOS PC and the older CentOS PC. There were some differences but I could not find out why I failed installation on a PC and why I succeeded it on another.
Too many days were wasted so I give up since I'm still only a novice on linux. I will go to Ubuntu or other linux out of CentOS.

Thank you very much~
Charlie.

Hi,

I installed TBS6985 driver on Ubuntu successfully without any errors. I checked the device through tvheadend administration pages too. TBS6985 is working well.

I still have question why CentOS is not friendly with it.
