Problem with compiling hello.c

Hi everyone,

I've got a small problem regarding compiling the hello.c like it was said in the wiki (http://www.nioswiki.com/installnios2linux). There was no problem doing the stuff before. I used the prebuild BinaryToolchain although i don't put it in the /opt directory (no permissions). The verifying works also [1].

When i want to compile the hello.c, i get this error [2]. I know that i have no permissions on /opt... the includefiles aren't there anyway. I'm curious why it wont touch the include files on /home/working/nios2/lib/gcc/nios2-linux-uclibc/3.4.6/include

Anyone got an idea? I think it might be linked up with the prefix stuff in the specs but i don't really know exaktly, i searched also for some config files, but none of them had any effects. For help, idea or even solution i would be grateful. :)

    the prefix seems to offer a clue: 

    --prefix=/opt/nios2

    maybe the prefix should be in your /home/working/... directory. is the prefix is defined in:

    note: i haven't tinkered with this, just took a look at your outputs

    i found also the

    but even if i change this, nothing happens *g*
