TCLIBC with newlib

TCLIBC with newlib

[Jonathan Richardson]

Hi,

I'm trying to create a toolchain using newlib as the libc. I set
TCLIBC="newlib". First error is:
ERROR: Nothing PROVIDES 'libgcc-dbg' (but
mc:crmu:/home/jon/work/yocto/stingray2/poky/build/../meta-brcm/meta-stingray2/recipes-zephyr/brcm-zephyr/brcm-zephyr.bb
DEPENDS on or otherwise requires it). Close matches:
  libgcc
  libgcc RPROVIDES libgcc-dbg
ERROR: Required build target 'brcm-zephyr' has no buildable providers.
Missing or unbuildable dependency chain was: ['brcm-zephyr', 'libgcc-dbg']

This is caused by LIBC_DEPENDENCIES in
meta/conf/distro/include/tclibc-newlib.inc:
LIBC_DEPENDENCIES = "\
    newlib-dbg \
    newlib-dev \
    libgloss \
    libgloss-dev \
    libgloss-dbg \
    libgcc-dev \
    libgcc-dbg \
    libstdc++-dev \
    libstdc++-staticdev \
TOOLCHAIN_TARGET_TASK ?= "${LIBC_DEPENDENCIES}"

TOOLCHAIN_TARGET_TASK = "newlib libgloss" seems to fix it. Why are the
dev/dbg packages required as
dependencies and why does it think the recipes for libgloss, libgcc,
etc don't provide them?

Then libtool-cross fails when autoconf checks if the compiler works
because it can't find _exit().
So I added this to my local.conf:
EXTRA_OECONF_append_class_target = " LIBS=-lgloss-linux"
EXTRA_OECONF_append_class_cross = " LIBS=-lgloss-linux"

But it still fails:

undefined reference to `_exit'

Has newlib ever been used to create a toolchain? I'm not sure what the
best way to work around all these
build tool dependencies is. Should we come up with a bunch of settings
and add them to tclibc.conf? I'm
wondering to what extent this has been tested.

Thanks,
Jon

Remove all -dbg packages from above list.

It should be EXTRA_OECONF_append_class-target and
EXTRA_OECONF_append_class-cross, there is a underscore there instead
of '-'

Thanks. More than this is required though. I added this so far:

Adding the dependency to binutils-cross-arm causes circular
dependencies though. I don't know
what's going on here:

Re: [poky] TCLIBC with newlib

[alhe]

[-- Attachment #1: Type: text/plain, Size: 29210 bytes --]

Hello,

I'm pretty sure, you are causing the dependency loop with the depends + 
cross class changes.

I think there is some wiring in libgcc that is not matching properly 
with something defined in your BSP layer, likely in your machine.conf, 
although like Khem said, removing the dbg packages from the dependencies 
would workaround this issue.

Yes, a newlib toolchain can be created, this works fine with the 
supported BSPs (and others from some vendors) AFAIC I dont think changes 
are required on tclibc-newlib at this point since it contains the 
basics, anything else would be added per architecture on their BSP layer.

Its hard to tell without knowing anything about the architecture you're 
using, but I think the error you are hitting its happening because your 
runtime isn't being built properly or is incompatible, it looks like at 
the very least you should have stubs for _exit() patched on 
libgloss/newlib for your architecture (or submit those to newlib 
upstream), if you're using something ARM based you may be able to build 
using semhosting with the rdimon specs or even nosys but it probably 
wouldn't work properly at runtime, if that allows you to build you can 
proceed to add you architecture specific functions to libgloss.


Cheers,

Alejandro

Re: [poky] TCLIBC with newlib

[Jonathan Richardson]

[-- Attachment #1.1: Type: text/plain, Size: 30648 bytes --]

Hi Alejandro,



Thanks for your feedback. I narrowed it down. It builds when building
simple code that uses a makefile to compile some MCU code running on a
cortex-m0. Now we’re compiling zephyr OS for a cortex M0-plus. The
toolchain is a bit more complicated because of all the x86 native build
dependencies.



Ignoring that for now I created a simple helloworld recipe with an empty
main compiled with autotools (attached). The problems arise when autotools
pulls in libtool-cross. If you switch to a makefile instead of using
autotools then libtool-cross doesn’t get pulled in and it builds fine. I
think the toolchain should be buildable when using autotools class and
newlib.



Here is how to reproduce. You can use any machine tuning.



build/conf/local.conf:

MACHINE = "cortexm0"

TCLIBC = "newlib"



conf/machine/cortexm0.conf:

DEFAULTTUNE = "armv6t-novfp"

require conf/machine/include/arm/arch-armv8a.inc



Apply attached patch then bitbake helloworld.



Note that with this simple example I don’t have the issue having to
redefine LIBC_DEPENDENCIES. The zephyr recipe pulled in various native
python modules that likely caused some issue there. Also there are no
circular dependencies with this. Thanks.

Hello,

I'm pretty sure, you are causing the dependency loop with the depends +
cross class changes.

I think there is some wiring in libgcc that is not matching properly with
something defined in your BSP layer, likely in your machine.conf, although
like Khem said, removing the dbg packages from the dependencies would
workaround this issue.

Yes, a newlib toolchain can be created, this works fine with the supported
BSPs (and others from some vendors) AFAIC I dont think changes are required
on tclibc-newlib at this point since it contains the basics, anything else
would be added per architecture on their BSP layer.

Its hard to tell without knowing anything about the architecture you're
using, but I think the error you are hitting its happening because your
runtime isn't being built properly or is incompatible, it looks like at the
very least you should have stubs for _exit() patched on libgloss/newlib for
your architecture (or submit those to newlib upstream), if you're using
something ARM based you may be able to build using semhosting with the
rdimon specs or even nosys but it probably wouldn't work properly at
runtime, if that allows you to build you can proceed to add you
architecture specific functions to libgloss.



Cheers,

Alejandro

Hi,



I'm trying to create a toolchain using newlib as the libc. I set

TCLIBC="newlib". First error is:

ERROR: Nothing PROVIDES 'libgcc-dbg' (but

mc:crmu:/home/jon/work/yocto/stingray2/poky/build/../meta-brcm/meta-stingray2/recipes-zephyr/brcm-zephyr/brcm-zephyr.bb

DEPENDS on or otherwise requires it). Close matches:

  libgcc

  libgcc RPROVIDES libgcc-dbg

ERROR: Required build target 'brcm-zephyr' has no buildable providers.

Missing or unbuildable dependency chain was: ['brcm-zephyr', 'libgcc-dbg']



This is caused by LIBC_DEPENDENCIES in

meta/conf/distro/include/tclibc-newlib.inc:

LIBC_DEPENDENCIES = "\

    newlib-dbg \

    newlib-dev \

    libgloss \

    libgloss-dev \

    libgloss-dbg \

    libgcc-dev \

    libgcc-dbg \

    libstdc++-dev \

    libstdc++-staticdev \



Remove all -dbg packages from above list.



TOOLCHAIN_TARGET_TASK ?= "${LIBC_DEPENDENCIES}"



TOOLCHAIN_TARGET_TASK = "newlib libgloss" seems to fix it. Why are the

dev/dbg packages required as

dependencies and why does it think the recipes for libgloss, libgcc,

etc don't provide them?



Then libtool-cross fails when autoconf checks if the compiler works

because it can't find _exit().

So I added this to my local.conf:

EXTRA_OECONF_append_class_target = " LIBS=-lgloss-linux"

EXTRA_OECONF_append_class_cross = " LIBS=-lgloss-linux"



It should be EXTRA_OECONF_append_class-target and

EXTRA_OECONF_append_class-cross, there is a underscore there instead

of '-'



Thanks. More than this is required though. I added this so far:

If you switch to a makefile instead of using autotools then libtool-cross doesn’t get pulled in and it builds fine. I think the toolchain should be buildable when using autotools class and newlib.

I think its a usecase which perhaps is not yet supported. I would
suggest to open a tracker ticket in yocto bugzilla for this, since it
won't be a one liner to fix it

> Its hard to tell without knowing anything about the architecture you're using, but I think the error you are hitting its happening because your runtime isn't being built properly or is incompatible, it looks like at the very least you should have stubs for _exit() patched on libgloss/newlib for your architecture (or submit those to newlib upstream), if you're using something ARM based you may be able to build using semhosting with the rdimon specs or even nosys but it probably wouldn't work properly at runtime, if that allows you to build you can proceed to add you architecture specific functions to libgloss.

I'm not sure you actually need/want libtool-cross? Have you tried
setting INHIBIT_AUTOTOOLS_DEPS = "1" ? That would let you set your
dependencies manually and only pull in the bits you really need/want
which might get you further. You may then need to add autoconf-native
and or automake-native to DEPENDS manually for your recipe.

Cheers,

Richard

Hi Tim. Yes I did. We're using the zephyr classes but we're on a later
version that requires use of a bunch of python tools. Adding the
additional dependencies exposed the problem.

Can we see if we can bring your changes to the meta-zephyr layer for the
benefit of everyone?

If you switch to a makefile instead of using autotools then libtool-cross doesn’t get pulled in and it builds fine. I think the toolchain should be buildable when using autotools class and newlib.

Ok thanks Richard. I'll do that. In my example I didn't use libtool
but most autoconf configs would and therefore it would need
libtool-cross. Since my attempts to add the proper flags to the tools
caused circular dependencies it's not a proper solution. I'll look
into it a bit more and see if I can come up with something. Having
this support would be useful.

Sure, I'll upstream it once these toolchain problems are worked out
and it's cleaned up more.
