How to cross compile libubootenv

[vinic...@gmail.com]

Hi,

I'm cross compiling swupdate for Debian armhf and I reached this point:
/usr/lib/gcc/arm-linux-gnueabihf/4.9/../../../../arm-linux-gnueabihf/bin/ld: cannot find -lubootenv

But I'm not able to find libubootenv nowhere. I did read that is take from U-Boot, but i'm don't know to generate it.

Thanks,
Vini

Hi Vini,

You need to compile U_boot, too, for your machine: libubootnv.a is
tools/env/lib.a when you compile U-Boot.

It is clear checking the recipe in meta-swupdate:

Best regards,
Stefano Babic

Hi Stefano,

Thanks a lot for quick reply. 

I did compile uboot tools with: make tools-all, and works! But I had to compile directly in target. :)

similar question pops up again and again, maybe we should add
FAQ section on the project's website.
