I'm going to guess that the caret is *supposed* to line up with the second comma on that line, rather than the "0", but it's close enough. It looks like "LINUX_VERSION_CODE" is undefined, so your code is being parsed as "generate_guest_id(0, ,0);" which is invalid C code. Questions, then: * Do you get the same error if you build vanilla Linux (i.e. from kernel.org? * How are you invoking this build? * What C compiler (and what version thereof) are you using? * Is there a reason you need what's now quite an old kernel? >
