@Andreas, please note this post.

Thanks for the info. I've recompiled the driver here.

Meanwhile I found a thread where you linked to your HOW-TO kmod build. I was able to create a virtual maschine with ClearOs 7.4 and developer envirenment. I used your script and build a driver.
The build was sucessful and works with 693 from ClearOS 7.4.

Choose an older one (not with 693 in the numbering) and it should boot to a 7.3 kernel rather than the 7.4 one.

Thanks for your fast support.

I use an older boot entry an that works with 3.10.0-514.21.2.v7.x86_64.
I plan to migrate to 7.4 in the future. So it would be nice if there is still a driver for aic7899 (Adaptec 39160)

I've compiled the driver for ClearOS 7 here.

Hello Nick,

i have trouble with this kmod for aic7xxx since there was an update to ClearOs 7.3 and newer. Since then the aic7xxx.ko went to /weak-update and wont work anymore.
Now I would like to bring up my system up to date but my tape library wont work anymore.
I searched for compiling the kmod driver by myself, but im sorry, im not able to finally solve it

I would like to learn how to compile kmod drivers for ClearOs. Could you please help me?

Best Regards
syned

The good thing about kmod drivers is that they should be independent of minor kernel upgrades, so you should be OK on all 3.10 kernels. I say should as occasionally a kernel update will break backwards compatibility. I've only seen that a couple of times with two Intel drivers. That is a good reason for others to learn to compile them as well. There there is not a single point of failure.

Hello again,

thank you very much, it works and my tape / autoloader are visible now. Nice Job.
If there will be a new kernel update, will this driver still works?

Greetings

You cannot use pre-compiled centos or el kernel modules as the ClearOS kernel is incompatible with them. You will need to compile your own from the srpm. I have a couple of generic scripts here, but see the following post for the build environment and stop before you install an editor as that is all you need. Ultimately it is the rpmbuild line which you need to execute. I may be able to build it when I get home tonight, but the more people who can build these kmod packages, the better.

i tried to install via yum:
