Unable to create a file in H5CPP

I am trying to run an example code given [here] (https://raw.githubusercontent.com/HDFGroup/hdf5/develop/c++/examples/h5tutr_crtdat.cpp) using VS code 2022.

  1. I have installed hdf5-1.14.3-Std-win10_64-vs17.
  2. Have added the include and lib path to VS code additional include and library path.
  3. Then added hdf5.lib and hdf5_Cpp.lib to additional dependencies.
  4. Under C/C++ → preprocessor definitions have added H5_BUILT_AS_DYNAMIC_LIB

The program builds successfully. When I run the code it shows error

Not sure if I am doing the setup wrong. I am quite new to H5CPP and VS. Any help is greatly appreciated. Thank you

Are you opening a file with a Unicode file name?

And, more specifically re: Unicode - is this a Japanese file on a system that uses code pages instead of Unicode?

No. The file name is just an english word. I am running the example file as such without any changes.
I tried providing absolute path name as given in this post and it stopped throwing error and created a file with some unreadable file name and format.

Then, I changed from debug to release configuration in VS 2022 and it resolved the issue.
Thank you. But I am just curious to know what difference it makes to run in debug or release configuration. If this is out of scope of this forum, it is okay to close this topic here.

My first thought would be that it has something to do with our library linked to a release flavor of the CRT and your application being linked to a debug CRT. I’m pretty sure those are two separate dlls that don’t share state.
