Hi guys!!
After modifying and slimming down my uClinux kernel, I proceed to compile it but......:s, but I have an error which i can't understand the reason.
Here, that's the error displayed on the screen after executing "make" command :

Thanks for your help.. I tried to install the other missing toolchain's parts but i did some wrong commands to modify the PATH and my system crash down :s
I hope found a solution without reinstalling Linux. In this case if you have any idea about reintializing Ubuntu's PATH let me know please..
Thanks a lot for your help

i dont know what you mean by "system crash down", but you shouldnt be changing PATH for all users (such as the root user).
the toolchain doc already shows examples of properly setting the PATH var:

I mean that I can't login in graphic mode. Finally, I created another user with Sudoers permissions and my system works again
I downloaded and extracted the other Toolchain's missing packages in “/opt”: "blackfin-toolchain-elf-gcc-4.1-08r1.5-14.i386.tar.bz2" and "blackfin-toolchain-gcc-3.4-addon-08r1.5-14.i386.tar.bz2". I modify my path like it's indicated in " docs.blackfin.uclinux.org/doku.php?id=toolchain:installing" and I executed the following command to determine if my toolchain works properly "bfin-uclinux-gcc --ver" and i have this result:
_________
Target: bfin-uclinux
Configured with:
/usr/src/packages/BUILD/blackfin-toolchain-08r1.5/../gcc-4.1/configure
--build=i686-pc-linux-gnu --host=i686-pc-linux-gnu
--target=bfin-uclinux --prefix=/opt/uClinux/bfin-uclinux
--enable-threads=posix
--with-sysroot=/opt/uClinux/bfin-uclinux/bfin-uclinux/runtime
--disable-libstdcxx-pch --disable-symvers --disable-libssp
--disable-libffi --enable-clocale=generic
--enable-version-specific-runtime-libs --enable-__cxa_atexit
Thread model: posix
gcc version 4.1.2 (ADI svn)
_________
So I'm now sure that the toolchain has been fully and properly installed.
But, I still have the same error when I compile uClinux :s

if you're still getting stdarg.h errors, then you still havent installed all the right packages. please read the whole page rather than just skimming it. like this section:

I tried to execute manually the following command "bfin-uclinux-gcc --ver" and it works normally
I can't understand what's wrong

are you testing it in the same session, or are you running `make` in one window and testing the PATH in a different one (which might have a different environment) ?

so what did you change ? you werent in the dir i said to start at, so setting the PATH like that would make no difference.
you need both bfin-uclinux-gcc and bfin-linux-uclibc-gcc in your PATH.

Thanks Mike, thanks a lot for your help.
I success the uClinux's compilation:D
The problem was caused by 'PATH variable' and 'sudo command'. I explain :
I'm using a debian distribution, so I usually use 'sudo' command to execute commands that needs a superuser's permissions.. It's the first part of my problem, because this method doesn't give me all superuser's rights.. So, I used the following command 'sudo bash' to balance completely to superuser mode.. Later than, I changed the PATH variable of root like what you had said to me in your latest message.. Finally, uClinux's compilation was performed successfully
Now I'm going to reduce the size of uClinux image from 3.6MB to less than 2MB to fit it in my ADSP-BF533 (32MB of RAM, 2MB of Flash memory)
Thanks a lot. With my best regards.

you should not be building anything as root. if you need to, you've set things up incorrectly.
only the toolchain install might need root access (if you want to put it at /opt/...).

When I try to compile uClinux as a user, I have a message indicates that I haven't permissions to execute the command..When I use Sudo I obtein the PATH error :s so I'm obliged to balance completely to root mode to compile uClinux successfully..

then fix the perms on the files (presumably the toolchain). building the dist as root is not supported and it should not be done.

I changed the files' permissions; exactly I added "wx" permissions to 'groups' and 'user' with "chmod" command..
After than, I tried to execute uClinux compilation in both of user mode and sudo mode.. But, I still have the same error :s..

by mixing sudo with non-root access, you've broken the permissions in the uClinux dist directory. your best bet is to `rm -rf` the uclinux-dist dir with sudo and then extract the tarball again as non-root. then never ever use `sudo` to run make.

Really thanks Mike for all your help,
I removed all uClinux-dist and I extract it again as a user.. I execute the make without neither 'Sudo' nor 'root mode'
It works
Thanks
