Remove note of GCC ABI change

问题:

When I compile my program with GCC 4.7 I get the following note:

/usr/include/c++/4.7/backward/binders.h:167:5: note: the ABI of passing structure with complex float member has changed in GCC 4.4 here 

Is there any way to get rid of it? I tried to google it, but all I find is the GCC source code line that prints the note string.

回答1:

Pass the option -Wno-psabi to GCC.

回答2:

I was getting the same message:

/usr/include/c++/4.8.3/bits/stl_pair.h:276:5: note: the ABI of passing structure with complex float member has changed in GCC 4.4 

for the following line of code:

indices.push_back(make_pair(centreIndex,centre)); 

where centreIndex is an integer and centre is a complex float.

To get rid of the error message I changed the code to:

indices.push_back(pair<int,complex<float> >(centreIndex,centre)); 

I think this is a better way of doing it because make_pair is just a wrapper for this more direct way of creating a pair.
