260 | Very rarely, people want to tweak EV even more, e.g. to exclude |
|
|
261 | or include certain watcher types or backends. This can be done by adding |
|
|
262 | extra -D options here, or via the EV_EXTRA_DEFS environment variable. |
|
|
263 | |
|
|
264 | For example, if you run into compile problems because of missing memory |
|
|
265 | fences (or you just want extra performance), you can tell EV to not support |
|
|
266 | smp and threads via -DEV_NO_THREADS. |
