Why i have an eror while patching dwm?

Question

I'm trying to patch config.def.h in dwm folder (patch -p1 -f < ../patches/dwm-alpha-6.1.diff), but i have some errors :( I tryed add to dwm alpha patch, which the add to dwm some transparency but i have some errors. I use patch -p1 -f < ../patches/dwm-alpha-6.1.diff, because i successfully patched gridmode in this way. But with alpha i have some errors... Oops:(

Patching in dwm is not perfect and you are not guarenteed any given patch will work especially if you have patched dwm before. If a patch fails like that you can either revert to your previous state( before patched ) or manually patch following the *.rej files.

To revert to previous state, you will find *.orig files example dwm.c.orig, config.def.h.orig, etc. Just copy these files to there respective source ie cp dwm.c.orig dwm.c.

To manually patch you will find *.rej files. Open these files and follow their appends and removals e.g if it sais

-       x = 0;
+       x = 1;

simply remove the first line and add the second. Hope I was clear enough, I'm not an expert but I hope this helps.
