Re: [meta-mingw] Patch needed to let linker find lto plugin

[Bystricky, Juro]

Could you please elaborate on what do you mean by "built it as-is".
I tested the meta layer with some cases I considered typical
or most common. (I think I enumerated them in my original
message). Apparently I missed one.

Thanks

Juro

Hi Juro,

My Yocto environment is for the Congatec QMX6 SoM that is built around a 
quadcore i.MX6.
I use the Yocto layers from the Congatec repository 
(https://git.congatec.com/public), which includes the meta-fsl-arm and 
meta-fsl-arm-extra layers.

My bblayers.conf is:

BBLAYERS = " \
   ${BSPDIR}/sources/poky/meta \
   ${BSPDIR}/sources/poky/meta-poky \
   \
   ${BSPDIR}/sources/meta-openembedded/meta-oe \
   ${BSPDIR}/sources/meta-openembedded/meta-multimedia \
   ${BSPDIR}/sources/meta-openembedded/meta-python \
   ${BSPDIR}/sources/meta-openembedded/meta-networking \
   \
   ${BSPDIR}/sources/meta-fsl-arm \
   ${BSPDIR}/sources/meta-fsl-arm-extra \
   ${BSPDIR}/sources/meta-fsl-demos \
   \
   ${BSPDIR}/sources/meta-mingw \
   \
   ${BSPDIR}/sources/meta-peek \
   ${BSPDIR}/sources/meta-peek-ecng \
"

The image I normally build (peek-image-ecng-acu-default) is based upon 
the core-image-full-cmdline image.

I built the MinGW SDK by adding SDKMACHINE="x86_64-mingw32" to my 
local.conf and typing the command "bitbake peek-image-ecng-acu-default 
-c populate_sdk".

I attended the Yocto developer day in Berlin last week. When I showed 
the MinGW linker LTO plugin error to Mark Hatle, he suggested applying 
his patch.

best regards,

Winfried

Thanks. I will re-run some basic tests again and
send the patch by Mark Hatle (applied to meta-mingw/krogoth) to the mailing list.

[meta-mingw] Patch needed to let linker find lto plugin

[winfried.dobbe]

Recently the meta-mingw layer was updated to krogoth by Juro Bystricky. 
Thanks !
However when I build it as-is, the linker fails because it can't load 
the lto plugin.

After applying commit a06e473590207f72b11d273a09de2c8a889c381e from 
meta-mingw-contrib (by Mark Hatle), the error disappeared.

See: 
http://git.yoctoproject.org/cgit/cgit.cgi/meta-mingw-contrib/commit/?h=mgh/jetho/meta-mingw&id=a06e473590207f72b11d273a09de2c8a889c381e

I think this patch needs to be applied also to the meta-mingw main 
repository.

regards,
W. Dobbe
