[Buildroot] Error when compiling Buildroot to create .iso (cannot stat /.../i386-linux-2.6.24-20

Fri Apr 4 02:03:20 UTC 2008

ok this is what I get after I remove the link (and my project named zero)

cp /mnt/lab/buildroot/binaries/zero/i686-linux-2.6.24-20080404 /mnt/lab/buildroot/build_i686/iso9660/kernel
cp: cannot stat `/mnt/lab/buildroot/binaries/zero/i686-linux-2.6.24-20080404': No such file or directory

You may want to see what is /mnt/lab/buildroot/binaries/zero/i686-linux-2.6.24-20080404.  It turns out to be /mnt/lab/buildroot/binaries/zero/i686-linux-2.6.24-20080404 -> ../../x86/boot/bzImage

With ../../ , it will move you back to the buildroot .  In this case, I remove my symlink in the buildroot directory, the build process cannot complete due to broken link.

Now I put the link x86 in my buildroot directory, I am using/running the command (with the only change on the project name from uclibc to zero) that I show you on the buildroot directory.

I run the command that I gave you and I see the problem too. :(  It seems like there is a cut and paste typo in the command.
It should be 'ln -s project_build_i386/uclibc/linux-2.6.24/arch/x86 x86'  Fixing that 2.6-24 to 2.6.24

To double check, you can "ls -l x86" it should show you some directory content instead of a x86.

P.S. final product:

Hope this help.

You can do a "find . -name bzImage -print" on "/root/buildroot" will show all the path that contain bzImage.  Only one contains the real file, all of them are just symbolic links.  I believe the script is trying to look for bzImage but it is a sym link point to somewhere it doesn't exists.

I want to boot up my newly created kernel in VirtualBox, and I will need an .iso to do that. So modified menuconfig to give me an .iso and typed make again. Unfortunately I run into an error that states:
