Re: [meta-freescale] MTD UBI undefined reference failed to build OE gatesgarth branch

Okay, I found the lines responsible for build/tmp-glibc in poky/meta/conf/distro/defaultsetup.conf. It appears that your config is using the default for this, while we are overriding:

# Allow single libc distros to disable this code
TCLIBCAPPEND ?= "-${TCLIBC}"
TMPDIR .= "${TCLIBCAPPEND}"

Hi Jupiter,

In that case, you could try building with MACHINE=imx6ullevk, then compare the builds.

One thing I don't understand is your log shows build/tmp-glibc/work. I'm only familiar with builds using build/tmp/work.

Hi Tom,

Thanks for your response and help.

Yes, indeed I was able to build it on the zeus branch and to work on
zeus for a long time.

It is not that problem,  I defined nand support in my machine
configure already, do you have a build system with bitbake, oe-core
(poky) for building gatesgarth branch so I can debug it?

Which branch should I build it? I pulled your fork, but I could not
find gatesgarth, so I used master branch to build, it still has many
undefined references:

Thank you very much.

Kind regards,
