[PATCH] kbuild: specify absolute paths for cscope

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Some tools (like my favourite editor, vim) can't handle relative
paths from cscope as soon as cscope.out is no longer in $PWD. Use
absolute paths when generating cscope.files, which seems to be
the recommended way to generate cscope.out, anyway (at least according
to cscope.sf.net).
