Thanks Shin, i only changed two things on it. I pressed enter on the fourth line to separate the @@, like this
From this
+++ b/src/game/Group.cpp@@ -322,10 +322,20 @@ bool Group::AddMember(const uint64 &guid, const char* name)
To this

@@ -322,10 +322,20 @@ bool Group::AddMember(const uint64 &guid, const char* name)
And on the last line (line 60) i pressed enter since it was needed for it to work on my ubuntu box. Gave it one more empty line at the bottom to compile with no warnings.
Tested and it compiled fine. After which i checked with a tauren hunter and a druid night elf to see if it worked (I activated the option allow 2 side group and other options except for guild 2 side). It did not work, it said it was unfriendly. Tested with 9074. What do you think it might be. Diid i miss something obvious am guessing.
