build nios2-elf-gcc with fedore4

Hi,

I try to build the compiler tools with fedora4. Binutils compiled and installed well.

Following error on the screen when trying building gcc : 

checking whether byte ordering is bigendian... cross-compiling...
unknown
checking to probe for byte ordering... /usr/local/nios2-elf/nios2-elf/bin/ld: crt0.o: No such file: No such file or directory
collect2: ld returned 1 exit status
unknown
configure: error: unknown endianess - sorry
/src/src/gcc/libiberty/configure: line 3289: exit: please: numeric argument required
/src/src/gcc/libiberty/configure: line 3289: exit: please: numeric argument required

I used : 

# ../configure --target=nios2-elf --prefix=/usr/local/nios2-elf --with-newlib --enable-languages=c,c++

and then make.

I'm using gcc32 (not gcc 4.0), and the sources from the linux CDRom from Altera (Nios2 - 5.0).

I first extracted GNUSRC.TGZ from the COMMON directory, and then copied in the sources found in LINUX/GNUBIN.TGZ

Any idea what I do wrong?

    You need the crt0.o from newlib.

    I try the build with the source from Nios2 window cd.

    I built binutils,gcc with c only, newlib, and gcc with c,c++.

    And it stopped at the last step for libstdc++, 

    checking for extra compiler flags for building...
configure: WARNING: No native atomic operations are provided for this platform.
configure: WARNING: They cannot be faked when thread support is disabled.
configure: WARNING: Thread-safety of certain classes is not guaranteed.
configure: error: No support for this host/target combination.
make: ***  Error 1

    I try with buildroot, and it stopped at the same message.

    Still finding...

    hippo,

    I had the same message in my first tests, but then I was still using gcc4.0 instead of the older gcc32.

    Someone from Altera can tell me how to build the tools??

    I am trying with gcc32 and buildroot to gcc3.4.5.

    The error message was from an improper def in the config.sub in gcc source,

    I fix it to 

    Index: package/gnuconfig/config.sub

    Then it can compile some libstdc++, but stopped at

    I will try other gcc 3.4.x.

    Hippo,

    Thanks for the time you put in this. I'll try the same you did so far.

    If it is so difficult, I just can not understand how the tools get build at Altera Corporation.

    Hippo,

    Yes, I need the stdc++ library, otherwise I can not use classes in a proper way.

    I don't need the C++ exception handling.

    We can try to enable more features in uclibc config using buildroot.

    hippo,

    Sorry that I can not support you very much, I'm not a linux/gnu... specialist, but I'm learning, ...

    Thank you anyways.

    It doesn't matter to me. I am not a c++ user. I just want to find out the problem.

    I think the configure does not work well. I will let you know if I have progess.
