Hi, I have tried to compile GCC 4.7.0 under Ubuntu 11.10 64 bit with the following configuration parameters: configure -v --enable-languages=c,c++,fortran --prefix=/opt/gcc-4.7.0 --enable-shared --enable-linker-build-id --program-suffix=-4.7.0 --enable-threads=posix --disable-werror --with-cpu=native --with-arch=native --with-tune=native --enable-nls --without-included-gettext --enable-clocale=gnu --enable-libstdcxx-debug --enable-libstdcxx-time=yes --enable-checking=release --with-system-zlib --with-fpmath=avx --enable-lto --with-ppl --with-cloog I get this error: mv: cannot stat `Makefile': No such file or directory /bin/bash: line 2: Makefile.tmp: No such file or directory make[7]: Entering directory `/home/username/Desktop/gcc-build/x86_64-unknown-linux-gnu/libstdc++-v3/src/debug' make[7]: *** No rule to make target `all'.
