With recent version of 'configure', came in revision 112028, generated Makefile contains wrong tool names for the native build. $ grep x86_64-redhat-linux Makefile AS = x86_64-redhat-linux-as AR = x86_64-redhat-linux-ar CC = x86_64-redhat-linux-gcc CXX = x86_64-redhat-linux-c++ if the output of config.guess does not match your --host=... string you are building a cross compiler. Try making those match or also specify --build. It appears that configuration scheme changed in revision 112028 of trunk without any notice. [trunk revision 112027] Host type: --build=BUILD configure for building on BUILD [BUILD=HOST] --host=HOST configure for HOST [guessed] --target=TARGET configure for TARGET [TARGET=HOST] [trunk revision 112028] System types: --build=BUILD configure for building on BUILD [guessed] --host=HOST cross-compile to build programs to run on HOST [BUILD] --target=TARGET configure for building compilers for TARGET [HOST] Thus for my purpose I need --build instead of --host for the trunk. Fixed. |
Bootstrap of GCC trunk (revision 112028) failed on ia64, x86_64 and i686 when configured with --host=... option. $ ../src/configure --prefix=/opt/gcc-42 --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --host=x86_64-redhat-linux $ make bootstrap >LOG Makefile:13360: warning: overriding commands for target `restrap' Makefile:12652: warning: ignoring old commands for target `restrap' configure: WARNING: If you wanted to set the --build type, don't use --host.
