I vaguely recall running into something like that myself. Some of |
44 |
these dependencies are not at all obvious. In general the make |
45 |
menuconfig (or especially xconfig) search options will quickly find an |
46 |
item even if it is hidden in the menu, and show you which flags aren't |
47 |
set in your context. Granted, that often leads to another search, and |
48 |
possibly finding other items not enabled. It rarely goes deeper than |
49 |
2-3 levels though. |
