Yes. I can understand your meaning. We test skyeye-1.2.3 on my Suse 10.2 and gcc version is 4.1.2. We have not enough linux distribution as our testing environment. Probably a GUI of SkyEye can solve a lot of issue of user
BTW: LPC is not supported.But other CPU supported by SkyEye, I think linux-2.6.20 can run on SKyEye for them, such as 2410.
