Yes, sorry, -nostdlib is not being used explicitly - but we seem to be getting the same effect with xg++ . The problem is then that the stage2 xg++ is not adding -lstd++ automatically, and the scripts are not adding it to the stage2 configure's LDFLAGS - I think they should be, or the part of them that is meant to be doing this has failed to do so in my case . Any pointers as to where precisely in the build script code to look for where -lstdc++ should be being added to the stage2 build LDFLAGS , or is it that xg++ should have been adding -lstdc++ if required , but wasn't ? Some clarification on that last point would be greatly appreciated.
