[oe] Error building gcc-cross

[martin mangard]

hello

I wanna run an application which depends on libstdc++.so.5.   I use
the default x86-machine configuration (i486) of the
"org.openembedded.dev" branch  to build the image. The default
provider for the libstdc++ is in my case "gcc-cross_4.3.4.bb" which
successfully builds "libstdc++.so.6"

I would like to create a  libstdc++ -compatibility package which
provides an additional  binary of the older version of libstdc++.
I started to play with the gcc-cross recipe.   "bitbake -b
gcc-cross_3.4.4.bb"  leaded to the following error.

I disabled  FORTRAN and JAVA which is also disabled for higher
versions of the gcc recipes and this error disappeared but the build
process stopped again with another error :

This is the content of my actual gcc-cross_3.4.4.bb:
#start
PR = "${INC_PR}.1"
FORTRAN = ""
JAVA=""

require gcc-${PV}.inc
require gcc-cross.inc
require gcc-configure-cross.inc
require gcc-package-cross.inc

#stop

Is there another recipe to build libstdc++.so.5. ?
How can I adapt gcc-cross_3.4.4.bb to fulfill my needs?
