Thank you in advance for your Attention !

Hi actris,

Which Linux distro do you use? ld-2.9 is quite old. Please try some latest distro.

Cheer,

Hippo

Hippo,

We use ubuntu 9.04 Jaunty... However we managed to compile (few minutes ago) the toolchain by using the gcc-4.2 instead of 4.3.

Do you have an idea why?

thanks

That&#39;s strange. Did you get Ubuntu updated ?

I have tested building on Fedora11 gcc-4.4.0 and Debian5 gcc-4.3.2.

- Hippo

On Suse with gcc 4.3.2 I can build the crosscompiler (though I get stuck with elf2flat right now).

-Michael

Yes, I have updated everything.

To sum up:

To compile 20090703 toolchain on a linux ubuntu 9.04 you need to do the followings :

- /nios2-linux/gcc3/gcc/collect.c line 1537 :

redir_handle = open (redir, O_WRONLY | O_TRUNC | O_CREAT);

needs to be rewrite as below

redir_handle = open (redir, O_WRONLY | O_TRUNC | O_CREAT,777);

- buffer overflow on nios2-linux-uclibc-ar

the toolchain need to be compiled with gcc4.2

and then it work properly... :rolleyes:

-Actris

Hi hippo,

Sorry for digging up this thread. I have a question about the nios-linux-20090730 pack.

Are you the developper of this pack ? I have one goal. I d like to understand a full port of linux on nios2 for my master thesis. Follow this link

http://www.alteraforum.com/forum/showthread.php?t=21531

this is my thread on altera forum where i explain my problem

Is this possible to know the construction detail of your pack ?
