Compiling Linux Kernel under Sitara

Kevin Cutts

I installed the 05.04.00.00 release of Sitara (under ubuntu) and want to compile the Linux kernel. When I issue the make command it fails to compile janz-ttl.c. So I comment out some of the stuff that fails and continue. It fails now on eeti_ts.c :-(

I can get make uImage to compile but thought a "bare" make should work to compile everything (The online documentation says it should work). (the failures are implicit functions which linux treats as fatal).

Any ideas?

The only time I've seen issues like you're describing is when I was overly "smart" in the past. I (incorrectly) assumed that the environment script should be sourced before trying to build anything. That was not the case, and in fact, because I had sourced that script it was causing my build to fail!!! That's a shot in the dark, but I thought I'd toss it out there just in case you're "smart" like me!!! :)

I haven't sourced anything before I did the build so I must not be as smart as you. ;-)

Ha! Not everyone can be so smart. ;)

FYI, I'm in the process of generating a log of my build so I can share a good build with you. Hopefully that will give you a clue as to whether something was installed improperly or somehow corrupted, etc.

Which processor is this for? I hope it's for the AM37xx SDK because that's what I just built!!!

Did you modify something with regard to kernel config? The file janz-ttl.c is not even attempted to be built, i.e. I don't know why it's even being compiled in the first place for you.

I ran the following commands:

make linux_clean
make linux | tee build.txt

I ran the "clean" step because I'm pretty sure I've already built this in the past. I only did "linux" as the target so it woudn't take forever. The build.txt file is attached.

Like you I suffered from "knowing too much". I was trying to build too far down in the tree. When I looked at your log, I realized this and just a few minutes ago, make linux finished successfully. A "bare" make is running now but I have little doubt that will succeed. Thank you for the help!

Thanks for reporting back. I'm sure we're not the only "smart" people out there making these mistakes! ;)

Thanks for the help Brad!
