RE: [Madwifi-users] make fails - kernel 2.6.4

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

I have gcc 3.3 natively installed on my development box, however
the kernel for the target machine is definitely cross-compiled with gcc =
3.2.3 (I have checked), and I am setting the environment variables to =
point to the cross-compiler tools and target kernel sources.  There must =
be some mistake in my settings / bug in the makefiles that is causing =
make to think that it should be using gcc 3.3 settings when it is =
actually using gcc 3.2.3.  Anyone have any insight into this?

hi matt

your gcc 3.2.3 does not know the compiler option
-funit-at-a-time which is set by your kernel config.
check the gcc version your kernel has been compiled
with and use this version.
