Yes,I have a compiler selected using "mex -setup C" i.e MInGW-w64.
What is the command line you are using?- Can I get more details on this because I am not using any command line.

The most important information is still missing: "See buildlog for compiler errors". You will find the details there.

Hi Jeevan,
This issue might be happening because the mex compiler is unable to find the CPP file for your function.This might happen as the CPP is a handwritten file instead of a auto-generated file.
This issue can be resolved if you could provide the missing file "_coder_addOne_info.c" to your path using the below command
srcFile = coder.const(fullfile(path, '_coder_addOne_info.c'));
