Module compilation error on another machine
Hi All, I am trying to compile simple kernel module. It gives following error. Same module compiles succesfully on another 64 bit ubuntu OS.Any idea what different in environment can cause this. Both machine are ubuntu 12.04. On 32 ubuntu bit compilation fails.

Suggested environments for kernel development
I would really like to know how you guys do your kernel development. What distro do you use and whats the process? I’m very comfortable with debian, but i’ve heard it’s not the easiest distro to build kernels for as you need to build to a .deb and apply it that way. ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
Re: Eudyptula Mail Format Issue
Hi, Surely It is in base64 format.which mail client you are using to submit? To be sure before sending the mail to Eudyptula,send it to yourself and check the mail format in view source option.It should not have base64 type. Possibly your logs attachment have some special characters which converts it to base64.

Not at all, any community-based distro is usually good for kernel development, pick one you feel comfortable with and use it. if you're going to just manually install the new kernel, then it makes precious little difference. on the other hand, if you really want to go through the packaging, then you can run one of: $ make rpm-pkg $ make deb-pkg other than that, as greg suggests, any even *remotely* current distro should work just fine. rday -- Robert P.
