[Buildroot] uImage could not be built before and after big bootloader patch

[Buildroot] uImage could not be built before and after big bootloader patch

[Ossy]

Dear mailinglist,

I am still not able to make a U-Boot image (uImage) of the linux kernel 
if I use "Same version as kernel headers". U-Boot is built before trying 
to make the uImage, but it still gives the following error:

...
"mkimage" command not found - U-Boot images will not be built
...

Am I forced to install U-Boot (meaning mkimage) on the host?
This is not neccessary if using "Advanced configuration".


Kind regards,
Marcus

Is this a regression of the bootloaders-cleanup branch ? As far as I
can see the non-Advanced configuration for the kernel never handled the
dependency on host mkimage. So I think it wasn't working before, and it
still isn't working.

I have another branch, linux-cleanup, that reworks all the code that
builds the kernel, so I'm really interested in improving the existing
code (of course, if it's a regression, I'll fix it).

Regards,

Thomas

No. However, the linux-cleanup patch removes the non-advanced/advanced
configuration schemes for building the Linux kernel to only keep one.

Do you have mkimage in output-build/host/usr/bin ? Can you try by
removing completely output-build ?

Yes, I would need to reproduce the issue. So please reproduce the issue
from a clean build, even if it involves doing :

 *) A build from scratch
 *) Removing some stuff
 *) Restarting the build

I haven't tested the mkimage dependency today, but I've implemented it
recently, and as far as I know, Peter tested it before merging the
bootloaders-cleanup branch, so I'm quite sure that it works in the
default case (i.e, build from scratch).

Thanks !

I managed to reproduce the issue. I will investigate.
