linux: having problems forcing a kernel recompile...

linux: having problems forcing a kernel recompile...

[Bob Cochran]

Hi,

I'm working with the latest poky master branch (as of this morning: 
876370419a), and I can't force a recompile of the kernel:

$ bitbake virtual/kernel -c compile -f

fails with

| make[2]: *** [prepare3] Error 1

I have seen this with both linux-qoriq and my own derived linux-yocto 
recipe.

I believe it's due to my sysroots kernel source directory not being clean.

When I initially bake my kernel, I can see that the do_populate_sysroot 
task is run and it copies a .config into 
sysroots/<machine>/usr/src/kernel.

When I try to force the recompile, MAKE sees that my source directory 
isn't clean and quits ( throws the prepare3 error ).

Somewhat related, I also notice that neither a

$ bitbake virtual/kernel -c cleansstate

nor a

$ bitbake virtual/kernel -c cleanall

actually cleans my kernel source directory.  Should it?


If these are legitimate bugs, I'll be happy to file a bugzilla report.


Thanks

Bob

These are due to some changes that we merged at the end of December to
improve kernel build times. We have bugs open for this issue, and set of
changes nearly ready that addresses this, and a few other pending issues.

Thanks Bruce for letting me know.  It's easy to work around - just 
delete .config & include/config from sysroot.

BTW, I'm browsing bugzilla but not seeing a bug entry that obviously 
covers these issues.

I'm looking at kernel-configuration, kernel-tooling, and linux-yocto.

Perhaps it's covered somewhere else?  Can you please let me know the bug 
id?

Thanks again,

Bob

Covers the same root cause.
