no i used this sudo name instead of my name. I am ariem here. so i have all access. I think there might be a PATH error i installed my compiler in /home/CodeSourcery/Sourcery_G++_Lite/bin So shall i export the path as export PATH=$PATH:/home//CodeSourcery/Sourcery_G++_Lite/bin or export ARM_TOOLCHAIN=/home/ariem/CodeSourcery/Sourcery_G++_Lite/bin/ is it right? which is correct one? Then what will come for export CROSS_COMPILE= why it is needed? -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
