[yocto] Antwort: Re: installation of kernel modules

[S.Jaritz at esa-grimma.de]

Hej  Daniel,

Building the modules as rpm works fine but it fails for deb. The deb 
generation process seems a little buggy. I have discovered problems with 
naming recipes (the QA tries to find the license by a "lowercased" link).

I checked the package dir. It is fine. The 3 files (a.ko, b.ko, & c.ko) 
are placed rightfully. The splitting into packages produces 3 kernel 
module packages and the 6 standard packages(like dev, static, local, etc). 
I think the problem is that the module will be compiled and deployed 
together with the kernel and the common packages later at the do_rootfs. 
That's why the myKernelModules recipe is deployed at the tmp/wok/<kernel> 
dir (and not at the tmp/work/<rootfs>).

Regards,

Stefan Jaritz

Take a look at deploy folder if your packages (rpm in my case) are
being created. I have faced problems where files go to -dev.rpm
packages and the yocto silently refuses to create empty .rpm package.
