An exception is triggered when the program get_started.cpp runs here, see what's going on?

Look! This is where the exception comes up, and the detailed is shown as follows:

Take a look where the red arrow points out, which said the exception was caused by ipopt-3.dll, but I am confused about that and I don't think so cause the example program included by IPOPT(no CppAD involving) worked very well and no any errors come up. I think perhaps this is caused by lacking of dll file of CppAD, but I am still finding the way of how to build it.

I now have access to my windows testing machine and tried the following in a visual studio 2022 command prompt:

git clone https://github.com/coin-or/CppAD.git cppad.git
cd cppad.git
mkdir build
cmake ^
   -G "NMake Makefiles"^
   -D cppad_cxx_flags="/MP /EHs /EHc /std:c++17 /Zc:__cplusplus"^
   -D cppad_static_lib=FALSE^
   ..
nmake check

and I got the following error:

... snip ...
C:\Users\bradl\repo\cppad.git\include\cppad/local/optimize/optimize_run.hpp(332): error C2668: 'CppAD::isnan': ambiguous call to overloaded function 
... snip ...

It seems to me that (since the code is inside the CppAD name space) the CppAD isnan (instead of the std::isnan) should have been chosen.

The following seems to fix this problem: In the file

\cppad.git\include\cppad/local/optimize/optimize_run.hpp(

Changing

isnan( play->GetPar(0) )

to

CppAD::isnan( play->GetPar(0) )

There are other place that this problem occurs. I am going to create a new commit on the master branch that fixes all of them.

The Visual Studio instructions should work for you (using the most recent master branch).
Please try it and report back.

That's cool!!! I will give it a try, but now I'm in the middle of my work, maybe I'll do it this weekend.

@Wang-Peng-debug Is this still a problem for you ?

[Wang-Peng-debug]

Um...maybe it's not suitable to configure on Windows, but I have another resolution for this and thanks for your caring
