[OE-core] [meta-mingw] eglibc-initial package getting in the way

[Francois Retief]

Hallo,

I am working on a MinGW SDK layer for OpenEmbedded.  At this point, I got
to the
point where the "gcc-crosssdk" package builds successfully.

My next target is to build the "nativesdk-libgcc" package. But the
"nativesdk-eglibc-initial package" is getting in the way. As one can see
from
the log output below, eglibc, it complains that the mingw32 environment is
not
supported.

So I switched TCLIBC in local.conf to "uclibc" in the hope that it would do
better,
but same error message. Same package gets built.

Also there is a BitBake warning about multiple package that provides the
same libc-for-gcc package. But when I run gcc-crosssdk, there is no such
clash.

Thus my question is, where does the eglibc package get included in the
dependency
tree? I worked through the package-depends.dot file to try and find what is
referencing this package but with no luck.

Cheers
  Francois
