hi all,

I try to compile "uClinux-dist-2008R1.5-RC3" to get the image of uClinux to load to my BF537 STAMP board.

I successfully get "Embedded Linux Configuration" window by

bash$ make menuconfig

After I compelete the configuration setting, I compile the kernel by

bash$ make

I got the erroes below,

==================================================

rm -f linux-2.6.x/usr/initramfs_data.cpio.gz

make ARCH=blackfin   CROSS_COMPILE=bfin-uclinux- -j1 -C linux-2.6.x  || exit 1

make[1]: Entering directory `/media/ubuntu-data/uClinux-dist-2008R1.5-RC3/linux-2.6.x'

rm: cannot remove `include/config/kernel.release': Permission denied

make[1]: Leaving directory `/media/ubuntu-data/uClinux-dist-2008R1.5-RC3/linux-2.6.x'

make: *** [linux] Error 1

===================================================

If I try to compile by root,

bash$ sudo make

I got the erroes below,

===================================================

rm -f linux-2.6.x/usr/initramfs_data.cpio.gz

make ARCH=blackfin   CROSS_COMPILE=bfin-uclinux- -j1 -C linux-2.6.x  || exit 1

you need to install the toolchain or set your path.

have you done that : http://docs.blackfin.uclinux.org/doku.php?id=toolchain:installing

Thank you for your reply.

I did install all toolchain. I check the PATH by "which" command

$ which bfin-uclinux-gcc

/opt/uClinux/bfin-uclinux/bin/bfin-uclinux-gcc

Is any thing I missed?

Thanks.

I bet bfin-uclinux-gcc isn't in your user path, but not root path (the only error about the binary not being found was when you ran make with 'sudo' ... did you run 'which' with sudo too?)  It's not good practice to be developing as root anyways.

If you take a look at the first error message you posted when you ran as a normal user:

rm: cannot remove `include/config/kernel.release': Permission denied

make[1]: *** [include/config/kernel.release] Error 1

I'm pretty sure this is a permissions error ...

post the output of: `ls -la include/config/kernel.release`

yeah, as Kyle hinted, it would seem you installed the toolchain as root (which is correct), but then you also unpacked the uclinux-dist as root (which is incorrect).  just delete the uclinux-dist and unpack it again as your normal user.
