populate_sdk and external toolchain

populate_sdk and external toolchain

[Eduard Bloch]

Hallo Yocto World,

I am having trouble with latest dora and the populate_sdk target. This
problem does not affect the stock configuration but because of some
specific features I need to use a custom toolchain from the board vendor
(made for Yocto 1.5) which is enabled with TCMODE. It contains the
compiler/binutils components and glibc but no locales.

The symptoms: it apparently tries to build the internal toolchain while
it shouldn't and fails on resulting conflicts.

It's very similar to the problem repoted for OE a couple of years ago
(quoted below, or see http://patches.openembedded.org/patch/33105/) so I
tried to add the modifications from there and from
https://www.mail-archive.com/openembedded-core@lists.openembedded.org/msg25653.html
and it didn't help at all. I couldn't spot a bug in the toolchain recipe
either, checked against
http://elinux.org/images/c/c8/ExternalToolchainsInYocto.pdf .

Does anyone have a good idea how to tackle this?

Thanks,
Eduard.

populate_sdk and external toolchain

[Manish Jaggi]

I am trying to build sdk (using populate_sdk option).
Toolchain being used is an external one.

When I run bitbake core-image-minimal -c populate_sdk, I get the below error

Is it possible to remove gcc-crosssdk from populate_sdk script ?

there should be a config.log file in build directory of libgcc which
should have more details as to why compiler failed
