Hello,

Please I need your help. I have been trying to execute a code on MAC terminal (MAC AIrbook M2) and I keep getting this error.

I have the latest Xcode installed and also yaml-cpp, CMake and GNU

The command I used: ./whidm.exe input/params.yml output/

The error: dyld[1361]: symbol not found in flat namespace (_cblas_caxpy)

zsh: abort ./whidm.exe input/params.yml output/

My friend using MAC Pro is also getting the same error, meanwhile another friend using a Linux computer is able to successfully execute the code.

So, I am certain this has to do with a setting or code I need to Make MAC work.

Please hep, as this is urgent and I can't proceed without this.

Is this a program that you built yourself? Or are you running a program that was built by someone and then given to you?

You need to follow up with the person who gave you this tool. It’s failing to run because it relies on the cblas_caxpy function from Accelerate framework but it’s not importing that framework correctly. In fact, the flat namespace part of that error indicates that it’s using a technique, the dynamic linker flat namespace, that’s very old and definitely not recommended. Whoever built this needs to update their build system to use more modern techniques.
