[Buildroot] longterm kernel releases: version-URI different for v2.x kernels

[Buildroot] longterm kernel releases: version-URI different for v2.x kernels

[Rick Robino]

Greetings,

I encountered problems automatically downloading kernel version 2.6.32.61, one of the current longterm releases.  It looks like the URL might have changed, so I thought that I would mention it here in case this fact might be news to anyone.

The longterm kernels are in a subdirectory called ?v2/.6/longterm/vA.B.C?.  Buildroot only looks in ?v2.6?, which works fine for standard kernels but not the longterm ones for 2.6.

Adjusting LINUX_SITE in linux/linux.mk solved the problem for me.

$ diff linux/linux.mk linux/linux.mk.orig
28c28
< LINUX_SITE = $(BR2_KERNEL_MIRROR)/linux/kernel/v2.6/longterm/v2.6.32/
---
> LINUX_SITE = $(BR2_KERNEL_MIRROR)/linux/kernel/v2.6/


I hesitated to submit this as a bug or a patch because the longterm naming scheme doesn?t seem consistent at kernel.org between 2.x and 3.x kernels.  But, I thought it might help others like myself who are just getting started with buildroot.

Apologies in advance if I?ve simply missed something in the configuration documentation.

Rick

Yes. Buildroot cannot guess if the kernel version you're using is a
"normal" version or a "longterm" version. Therefore, when you choose to
only give the kernel version in the configuration, it only looks in
2.6/ or 3.x/. If you need a kernel version that is available in some
other location, then you should use the "Custom tarball" configuration
choice, which allows you to pass an arbitrary URL to a tarball,
either located on kernel.org or on some other place.

Best regards,

Thomas

I suspected that there was a ?right way?.  Thank you, Thomas.

This same question popped up a while back as well, maybe we should add
this catch in the help text of one of the linux options...
