Hi, guys,
More errors occurred from the head file cstring in g++ 13.2.0. Please see below and could someone please tell me how to fix them? I check the head file cstring and did not understand why cstring head file is like that?
I look forward to your solution to the error occurred from the head file cstring.
Thanks again,
Dingjun

Subject: Error from memcpy in cstring
Hi, guys,
Please see below and how to fix this error?
PS C:\Users\Dingjun.Chen> g++ --version
g++.exe (MinGW-W64 x86_64-ucrt-posix-seh, built by Brecht Sanders) 13.2.0
Copyright (C) 2023 Free Software Foundation, Inc.
I did include the following head files in _d_dngl.cc
include/c++/13.2.0/cstring
/home/Dingjun.Chen/DAQ_XYZCross2_cmake_v5/src/_d_dngl.cc:284:9: error: 'memcpy' was not declared in this scope
284 | memcpy(aRandom1, aDeCrypt1, 8);
| ^~~~~~
/home/Dingjun.Chen/DAQ_XYZCross2_cmake_v5/src/_d_dngl.cc:284:9: note: 'memcpy' is defined in header '<cstring>'; did you forget to '#include <cstring>'?
I look forward to your help and hearing from you!
Thanks & regards,
Dingjun
