Hello ITKers,

My name is Suren. I am having an issue while installing ANTs in Mac Big Sur. It says

"HDF5 CXX compiler wrapper is unable to compile a minimal HDF5 program.  
“HDF5 C compiler wrapper is unable to compile a minimal HDF5 program.”

I am waiting for your favorable response.

I have attached a screenshot.

This is a support forum for ITK, not ANTs. The proper place for this question would be [ANTs issues](https://github.com/ANTsX/ANTs/issues).

But you should probably update the question before posting it there. Did you follow the [build instructions](https://github.com/ANTsX/ANTs/wiki/Compiling-ANTs-on-Linux-and-Mac-OS)? Did you change some settings or kept the defaults?
