If you need support, post the topmost build error, NOT this status message. ############################################################################### I tested 2.6.12 (excluding some patches from 2.6.11-r2 which didn't applied cleanly with newer version) and everything compiles and installs as expected. (I get many warnings, but no errors!)
patch from bug #97556 fixes this problem. *** This bug has been marked as a duplicate of 97556 ***
