Hi,
Is arm-linux-gnueabihf-gcc not a cross compiler then?, it is in make output
Thanks
Jose

That is not a cross-compiler. That is a cross-built native compiler.
To build that you need to have a cross-compiler already.
You want to just do a
$SOURCE_DIR/configure --prefix=$PREFIX --target=$TARGET
and no --host, and the other configure options only after you have seen
you do need them.

This is defined in ginclude/unwind-arm-common.h . Figure out why that
isn't included in your config?
Or maybe it already works better if you no longer do superfluous and/or
cargo-cult configure options :-)
