I can add all sorts of other outputs from the created toolchains if it helps. I wouldn't put the installed compiler (i.e. the prefix=) into the same directory as the sysroot. The sysroot should be a clean & pristine copy of the root directories on your target. It isn't written to, only read from. Once you have done your make install you should have a set of target libraries that work in your prefix/lib. You can't mix the c++ and libgcc libraries you just built with the versions on your target system. It should be possible to install the newly-created ones side by side with the versions on your target system. If that still doesn't work, time to start gdb. Andrew.
