c++ - Defined in discarded section error -

-

i have struct type defined in header file mystruct.h struct mystruct {...};.

then have declared 1 struct object in main as:

mystruct s;

and once in class header in same way.

this doesn't work, giving error:

`_zn10mystructc2ev' referenced in section `...myclass...'  of.../module.pre.o: defined in discarded section  `.text._zn10mystructc2ev[_zn10mystructc5ev]' of .../module.pre.o

if have struct in class works, need in main. how can solve?

define :

extern mystruct s;

in header file.
