Hi, all,
hecke/msymbols.h:109: warning: `MSymbols::chi' will be initialized after
hecke/msymbols.h:108: warning: `int MSymbols::k'
The lines in question are in a class definition (MSymbols) in a .h file, and look like
108: int k, N ; // weight, level
109: Character chi ; // character
110: bool do_save ;

C++ recommends that initialiser lists (in your constructor) initialise data members in the same order as they appear in your class / struct.


Are you perhaps ...?

MSymbols:MSymbols (const Character & p1, int p2, bool p3)
	: chi (p1), k(p2), do_save (p3)

Ayup...that seems to be it.

As noted in my original post, I have this:

Could it have to do with this (appearing first in the class definition)?
MSymbols (const Character& chi, int k=2, bool save=false) ;

The "obvious" fix isn't (I gather default values can be given only at the end of an arg list), so I reversed the order of declaration in the class. Piece of cake.


Is there a site or a source for tips like this? I have a few more warning messages weighing heavily on my conscience.

Thanks for the help!

Regards,

Justin
