RTL8192cu from source for CentOS 5

Postby apolonio » 2013/02/23 10:37:25

I got another Wifi USB unit today and it was the second one based on the RTL8192cu chipset.

I know that it is available via ELRepo but put together something in case someone wanted to install from source.

In case anyone else is interested.

Why would anyone want to install from source when the driver is available from ELRepo?

ELRepo version: survives kernel upgrades, does not require a development environment to be installed, well maintained and regularly updated.

Source install: breaks every time the kernel is updated, requires a huge list of development packages to be installed, will never get updated unless you go out and get the new source and start over.

I wanted to fit CentOS on a system with 128MB of Flash and 1GB of RAM and needed to trim down the kernel and remove some other things in there.

Also, I have another environment/build process with no 3rd party repos, no dag, no atrpms, no elrepo. No CentOS plus either, so I needed to figure it out from source.

Just sharing information in case someone ever needs to go this route like how I had to.

RTL8192cu from source for CentOS 5

How can compiling from source possibly require less RAM and disk space than a precompioled module?
Your arguments hold no water.

On this smaller system, I compile it on another machine, and just copy the /lib/modules/(kernel), I confused the issue when I mentioned that, so in hindsight I should not have said anything regarding the project I am working on.

You ask when someone can't use elrepo, my response is because maybe they can't use a 3rd party repo, just the stock CentOS (or RHEL). I wasn't sure if the rpm installed firmware, I checked and IIRC it didn't.

Also, I did this to share what I went through, there may be another Wifi adapter out there that is not in ELREPO, maybe someone can benefit from what I went through.
