[oe] Q: build/install gpe-image from dev branch

[Vladislav Grinchenko]

Michael,

thanks for the hint - of course, I overlooked a side note about gcc
2.95.3 toolchain on wiki!

That problem being solved, I still cannot complete 'gpe-image' build for
dev branch for collie target. The build process chokes on building
'hostap-modules-0.4.7-r4' package - somehow the package insists on
kernel version 2.6.18 (or it seems to be that way), but 'collie' as
rightly pointed out only accepts linux 2.4.18.

Here is my local.conf
------------------------------------------------------------------
DL_DIR = "/stuff/sources"
BBFILES="/stuff/org.openembedded.dev/packages/*/*.bb"
BBMASK = ""
PREFERRED_PROVIDERS = "virtual/qte:qte virtual/libqpe:libqpe-opie"
PREFERRED_PROVIDERS += " virtual/libsdl:libsdl-x11"
ASSUME_PROVIDED += "virtual/arm-linux-gcc-2.95"
TMPDIR = /stuff/tmp.dev
MACHINE = "collie"
DISTRO="openzaurus-unstable"
IMAGE_FSTYPES = "jffs2 tar"
BBINCLUDELOGS = "yes"
------------------------------------------------------------------

and the last lines of the failed compilation:

------------------------------------------------------------------

So, should I exclude 'hostap-modules' somehow with PREFERRED_PROVIDER?
And if so, what would be the syntax?

thanks in advance,

P.S. I promise to document my *journey* in OE world in a HOWTO for
newbies like myself if I ever get gpe-image built successfully.
