[Buildroot] I really need some help

Wed Mar 5 22:02:18 UTC 2008

I have been trying for the past 2+ months to successfully complete a
buildroot session for a AT91SAM9260EK. I first installed buildroot via
svn. Then I then did a "make at91sam9260pf_defconfig" to get baseline
config files. Then I ran a "make configured" in order to get a baseline
codeset. I ran "make menuconfig" in the kernel directory in order to
update the kernel config from what defconfig installed, otherwise I kept
getting prompted about missing config info during the make. The only
change I made to the kernel config was to add USB ACM support so I could
talk to a USB wireless module. I have tried both 2.6.22.1 and 2.6.22.10
kernels.

I have been able to figure out workarounds for some of the errors I have
gotten, either manually downloading source files that buildroot could
not find or creating directories that buildroot could not find or would
not create itself. Now I am getting an error about "No mail command
specified". Log file info follows:
