How to fix the fatal_error?

[Azadeh]

Hi
I get the error "/usr/include/c++/5/cstddef:51:11: error: ‘::max_align_t’ has not been declared
   using ::max_align_t;
           ^"
So I should update the libraries because I find this solution: "A workaround until libraries get updated is to include <cstddef> or <stddef.h> before any headers from that library."
I wrote some command on the Ubuntu terminal such as:
 "sudo apt-get install apt-file
sudo apt-file update
apt-file search stddef.h"
Then still the error exist.
Thank you

What are you trying to do when you get that error ?

[Azadeh]

Make, I wrote "make" in the terminal.

[Mark Greaves (PCNetSpec)]

To make what exactly.....

You're not giving anywhere near enough information ..

What are you trying to compile ?

Where did you get the source code ?

Which distro / version / architecture (eg. Ubuntu 14.04 64bit) ?

[Azadeh]

To make what exactly
before writing make I wrote "cd", exactly "cd gen" that gen is folder include c++ codes.
What are you trying to compile?
yes
Where did you get the source code?
I get the source code on a personal page, do you need it?
Which distro/ version/ architecture?
ubuntu-15.10-desktop or server-i386 64bit

fixed the error by adding "includes cstddef>" at the first line of some pages of codes, but now the newer error "narrowing conversion of long long int to long unsigned int inside {} [-Wnarrowing]

the source code relative to it:

I think error got from

I get the source code on a personal page, do you need it?

It would probably help.

this error solved, I asked about the new fatal_error.
