[gentoo-embedded] How to use EXTRA_ECONF with crossdev

[gentoo-embedded] How to use EXTRA_ECONF with crossdev

[René Berber]

Hi,

I know this works:

EXTRA_ECONF="--enable-targets=x86_64-w64-mingw32,i686-w64-mingw32"
crossdev -t x86_64-w64-mingw32 ...

But is there a way to use it for a specific tool?  I'd like to use it
only for binutils.

BTW the mingw64-runtime available is too old (i.e. version 1.0 snapshot,
when current is version 3.0b from svn, 2.something from releases).  I
created my local ebuild for this.

Also the crossdev ebuild available has the "cxx nocxx" bug, I had to
unmask the 20111118 ebuild.

crossdev --help
....
--[bgkl]env env          Specify env settings for binutils/gcc/kernel/libc

So perhaps crossdev -benv EXTRA_ECONF="--enable-targets=x86_64-w64-mingw32,i686-w64-mingw32" ...

Yeah, time to unmask it I think

Environment vars is not the same as adding parameters to configure, but
I haven't tested this option, maybe I'm wrong.

Thanks for your reply.

Sure it is, it is the only way to pass configure params I know.
I have used --genv EXTRA_ECONF='"--disable-secureplt --with-cpu=e300c2 --without-long-double-128 --with-dwarf2 --without-fp --with-fp=soft"'
to pass configure options to gcc only

Hi. Currently I have no idea how to make this work with crossdev, but
take a look at portage manual page (man portage) on package.env file
description.
