Error Compile uCLinux for Nios II

--- Quote Start ---

Hello everyone,

I can not fill uCLinux for nios2, I followed all the procedures of the site: http://www.nioswiki.com/, but each one gives me error.

I am trying Ubuntu 9.10 x86_64

Can anyone help me?

I hammered on those instructions over and over and never could get past building the toolchain. Once I downloaded the pre-built toolchain I could build the kernel pretty easily.

What step are you getting stuck on and what is the exact error message?

1) I tried to build the toolchain downloading http://www.niosftp.com/pub/uclinux/nios2-linux-20090730.tar but gives the following error:

                                                                   inlined from ‘col-
lect execute’ at /home/thor/Scrivania/progettoEmbedded/nios2-730/toolchain-build/..
/gcc3/gcc/collect2.c:1537: /usr/include/bits/fcntl2.h:51: error: call to
‘ open missing mode’ declared with attribute error: open with O CREAT in second
argument needs 3 arguments

2) I tried to build the toolchain downloadinghttp://www.niosftp.com/pub/linux/nios2-linux-20090929.tar but gives the following error:

libpthread/linuxthreads.old/wrapsyscall.c:101: error: redefinition of ’msync’ ./in-
clude/sys/mman.h:97: error: previous definition of ’msync’ was here

3) I used pre-built toolchain:

- http://www.niosftp.com/pub/gnutools/nios2gcc-20080203.tar.bz2

and uCLinix-dist-20100628

ma dà tanti errori su include/linux/types.h dopo aver lanciato il comando "make"

I hope you can help me, thanks

I'll do my best to help but it sounds like I barely got further than you. I have two Linux systems I have been playing with this on. An Ubuntu 10.04 laptop and a Fedora Core 13 laptop.

I'm like you, I wanted to try the latest and greatest version (20100628) but ran into problems.

I gave up on the toolchain build. I tried 3 different tarballs with 3 different versions of GCC and it failed every time.

Here's what worked for me to at least build the kernel zImage:

Download and install the prebuilt toolchain. Be sure to use their exact command to untar the toolchain to preserve permissions and links and such:

From http://www.nioswiki.com/operatingsystems/uclinux/binarytoolchain (http://www.nioswiki.com/operatingsystems/uclinux/binarytoolchain):

sudo tar jxf nios2gcc-20080203.tar.bz2 -C /

Then I un-tarred the 20090730 version and changed into that top level directory and ran

./checkout

I then followed the directions on http://www.nioswiki.com/operatingsystems/uclinux/uclinuxdist (http://www.nioswiki.com/operatingsystems/uclinux/uclinuxdist) and got a "zImage" output which I believe is the kernel image. Trying to test it now but having some SDRam issues.

I can't wait until I get my hardware shaken out and can move to Linux completely. The NIOS Eclipse tools I am not liking at all. .

I never succeeded in building it on 64-bit. I recommend using a 32-bit machine to build the toolchain (if you need to build it at all). The binaries will work fine on 64-bit.

Now, this signal problem:

I tried 32-bit but it gives the same error

I don't remember if this is for this error, but I have this fix to build on Ubuntu:

no longer gives that error XD ... has come to describe the memory map and gave this error:
