Honored Contributorbuild 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...

Altera_ForumYou 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++,
I try with buildroot, and it stopped at the same message. Still finding...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- Altera_Forum
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?? Stefaan - Altera_Forum
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
Then it can compile some libstdc++, but stopped atIndex: package/gnuconfig/config.sub =================================================================== --- package/gnuconfig/config.sub (revision 13473) +++ package/gnuconfig/config.sub (working copy) @@ -299,8 +299,8 @@ basic_machine=mt-unknown ;; nios2 | nios2-* | nios2 | nios2-*) - basic_machine=nios2-altera - os=-none + basic_machine=nios2-uclibc +# os=-none ;; # We use `pc' rather than `unknown'

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. Stefaan - Altera_Forum
I checked the altera's config by "strings nios2-elf-c++.exe".
There is no problem in your config. But they didn't have libstdc++ ... Do you use libstdc++ ? I am still checking... http://gcc.gnu.org/install/ (http://gcc.gnu.org/install/) - Altera_Forum
Using the source from Nios2 window cd,
I try remove the dir libstc++-v3 from gcc source tree, and it build nios2-elf-c++ http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif - Altera_Forum
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. Stefaan - Altera_Forum
We can try to enable more features in uclibc config using buildroot.

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.
