Hi,
I have built gcc 4.8 successfully with the configuration:
../gcc-trunk/configure -v --with-pkgversion='ubuntu12.04-64'
--enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr
--program-suffix=-4.8 --enable-shared --enable-linker-build-id
--with-system-zlib --libexecdir=/usr/lib --without-included-gettext
--enable-threads=posix --with-gxx-include-dir=/usr/include/c++/4.8
--libdir=/usr/lib --enable-nls --with-sysroot=/ --enable-clocale=gnu
--enable-libstdcxx-debug --enable-libstdcxx-time=yes
--enable-gnu-unique-object --enable-plugin --enable-objc-gc
--disable-werror --with-arch-32=native --with-tune=native
--enable-checking=release --build=x86_64-linux-gnu
--host=x86_64-linux-gnu --target=x86_64-linux-gnu
However, when I try to compile a test file, the search path is really strange:
ignoring nonexistent
directory“usr/include/c++/4.8”******************************************There
is no slash!
ignoring nonexistent
directory“usr/include/c++/4.8/x86_64-linux-gnu/.”********************There
is no slash!
ignoring nonexistent
directory“usr/include/c++/4.8/backward”******************************There
is no slash!
ignoring nonexistent directory“/usr/local/include/x86_64-linux-gnu”
ignoring nonexistent
directory“/usr/lib/gcc/x86_64-linux-gnu/4.8.0/../../../../x86_64-linux-gnu/include”
Any one can help? Thank you!
Regards,
Yao Yuan.

Why are you using --with-sysroot ?

Thank you! That's the problem! Just remove it!

Ubuntu (and Debian, maybe?) use --with-sysroot=/.
$ gcc -v
