This is related to the "c++ includes not getting searched for correctly?" thread. As Arnaud has said, the "--with-gxx-include-dir" option is not correct and does not solve the problem. As I have mentioned, I think that creating and removing the ${CT_SYSROOT_DIR}/include symlink is also wrong and suggestive that we are forced to create this because we are making a mistake somewhere else (binutils? gcc_static/shared_core? libc-startfiles?) and we should fix that problem first. I believe that if we can solve that problem, the c++ headers issue will go away. I will focus on this issue today, and will have some updates later. -Bryan -- For unsubscribe information see http://sourceware.org/lists.html#faq
