That is probably the best I couldn't even find such a list on the spca5xx website. If you've got a pointer, I'll gladly take the discussion there. > place to discuss this.

I wouldn't be building a Fedora kernel, I'd be building a kernel.org kernel, which most definitely is qualified against gcc versions earlier than 4.x. But I do see your point. > > It makes more sense to use GCC4.x without -O. But just for the > driver. Surely you can build the driver without building the kernel. Well sure, but since the spca5xx developer said that he thought gcc-4.x was the problem, I figured it would be a better use of my time to not spend time on gcc-4.x, and isolate whether the version of gcc that the spca5xx dev claims is 'good' truly is. > > I must admit that the following message disturbs me.

Overall, i'm not at all impressed with spca5xx or its management. -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ L.
