What more have i do? The problem that you're running into is that gcc is just the compiler, it is not the C library. If you try to build a cross compiler without a libc (i.e. just using what comes with gcc) you will get something that is not very useful as it can't link any programs -- which also means it won't be able to build libgcc or libstdc++ or any of the other required support libraries, let alone a "hello world" C program. This is probably not what you want. One way to supply these items is with a sysroot. Take the relevant items from the target system (e.g. /usr/include and /usr/lib or whereever they are located) and reproduce them in the same tree structure in some subdirectory on the cross host. Then supply the top of that location as --with-sysroot=/foo/bar when configuring the cross compiler. If you don't have an appropriate target system to get a copy of these files from then you're in a bit of a pickle. If the target is open source you can use a more complicated process to bootstrap them from source, but when you're targeting a proprietary target like HP-UX there's really no choice but to copy them from the target system.
