Error : ‘template<class> class std::auto_ptr’ is deprecated

Question

I'm using scons and ubuntu. When i when i make some program in using 'scons', there happen error like,

src/db/DBTextLoader.cc:296:3: error: ‘template class std::auto_ptr’ is deprecated [-Werror=deprecated-declarations]

/usr/include/c++/5/bits/unique_ptr.h:49:28: note: declared here template class auto_ptr;

and this is my command;

$ ./configuer

$ source something.sh

$ scons

Actually, I don't have any idea. I'm already searching this site and google. But I didn't find solution.

this is my g++ version (and c++ also was same version.)

g++ (Ubuntu 5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609

have any idea? Thank you.

Update to a later version of the package you try to install? One that doesn't use obsolete functionality. Or if there's no later version then search for another package that does what you want while still being actively developed. — Some programmer dude

No not the compiler, the package you want to configure and use scons on. The "program" you have downloaded. — Some programmer dude

If you read some books of Scott Meyers, he strongly recommends not to use auto_ptr. Actually, new compilers may restrict it's usage because of lots of possible problems with it when using auto_ptr in STL containers, etc.

Instead, you should use std::unique_ptr if you don't want more that one copy of the object, and std::shared_ptr if you need to copy the pointer.
