There are 2930 Makefiles in the kernel source. > One easy way is to add a > -Wno-error at the end of your command lines. Or even just -w if you > want or need a bigger hammer. I tried that. Some of the Makefiles check an environemnt variable as well if you want to turn off -Werror. It's not a complete solution at all. I have no idea what a complete solution looks like because I gave up. > > Or nicer, put it all in Kconfig, like powerpc already has for example. > There is a CONFIG_WERROR as well, so maybe use that in all places? That's a good idea but I'm trying to compile old kernels and not the current kernel. regards, dan carpenter
