linux-4.1-rc7 and dev versions of gcc

[David Binderman]

Hello there,

Recent development versions of gcc have started using the 6.0.0 version number.

gcc version 6.0.0 20150607 (experimental) (GCC) 

Linux kernel doesn't understand any gcc version numbers beyond 5.

include/linux/compiler-gcc3.h  
include/linux/compiler-gcc4.h 
include/linux/compiler-gcc5.h

Kernel build fails because no compiler-gcc6.h file.

I have a temporary bodge to copy compiler-gcc5.h file into compiler-gcc6.h


Regards

David Binderman

This shouldn't be a Sparse issue.  As discussed previously on this list
and LKML, Sparse should probably declare a specific GCC version number,
*not* the latest.  Apart from that, handling GCC 6 has been discussed on
LKML previously, and I think there were some patches circulating
already.
