[Buildroot] MTD build failing: undefined ref's to bcopy, bcmp

[Buildroot] MTD build failing: undefined ref's to bcopy, bcmp

[Grant Edwards]

The u-boot-env-tools-on-target build was failing because mtd.h
wasn't found, so in an attempt to fix that I tried selecting
BR2_PACKAGE_MTD and BR2_PACKAGE_MTD_UTILS.  Now that's failing
to build because of undefined references to bcopy, bcmp, bzero
(make output below).

Is there a trick to get mtd stuff to build?

Is BR2_PACKAGE_MTD/BR2_PACKAGE_MTD_UTILS actually what I need
to provide mtd.h for building the u-boot env set/get target
tools, or does mtd.h come from somewhere else?

Found it:

https://bugs.uclibc.org/show_bug.cgi?id=841

I'm getting the feeling tht I should have stuck with the last
release instead of using HEAD.  So far the number of packages
that won't build cleanly is at 4 and counting.

Still working on that one.

It's actually mtd/mtd-user.h that's missing.  It looks like it
should come from the kernel headers. It's there in the kernel
source tree (and in /usr/include on my development hosts), but
it's missing from the toolchain's usr/include directory.

How do you get mtd/*.h header files included in /usr/include
when the toolchain is built?

I patched the bug in the mtd package so it's now building, but
it won't run:

   # flash_info
   flash_info: can't load library 'libgcc_s.so.1'

libgcc_s.so.1 appears in the staging directory,

   $ find . -name libgcc_s*
   ./output/staging/usr/arm-linux-uclibc/lib/libgcc_s.so
   ./output/staging/usr/arm-linux-uclibc/lib/libgcc_s.so.1

but it's not present in the target filesystem.

Am I having all of these problem becuase I shouldn't be using
HEAD, or am I doing something else wrong?

Are you using a buildroot-generated toolchain or an external toolchain ?

The MTD utils package has very recently been updated into HEAD, which
might explain why you're encountering so many failures.

Yes. :)

It's an external toolchain that was generated by buildtoot.

I can try using an "internal" toolchain, but that approach
really slows down work since each "guess" takes 40-50 minutes
instead of 10-12.

The problem is that buildroot expects to find libgcc,
libstdc++, et al in $(SYSROOT)/lib

That's not where buildroot puts them.

Buildroot puts them in $(SYSROOT)/usr/arm-linux-uclibc/lib

Apparently, toolchains built by Buildroot aren't suitable for
use as external toolchains without some post-build massaging.

Yes. I have a fix in one of my branches that fixes this. But it's part
of a set of fixes designed to get Codesourcery toolchains to work in
Buildroot, which doesn't work yet (see my mail on this topic a few days
ago).

See
http://git.buildroot.net/~tpetazzoni/git/buildroot/commit/?h=toolchain-fixes&id=27bd3ec803202f52c336254b276cbab3c6999a35

(but it's not ready for inclusion yet)

Yes, we need a workaround similar to what we are doing for
mtd-utils.git. I've checked in a fix for this earlier tonight.

This broke when we updated to mtd-tuils 1.2.0. I'll update to 1.3.1
tomorrow after a bit of testing.

No, mtd.h normally comes from your kernel headers.
