Windows: Missing Intel runtime DLLs after pip install xara (Error 126: The specified module could not be found)

[romagnoliFer]

Hello,

There seems to be a problem with missing Intel runtime DLLs when installing and using xara from PyPI.

After installing xara via pip install xara on Windows, running the library results in multiple “Error 126: The specified module could not be found.” messages for the following DLLs:

libifcoremd.dll
libmmd.dll
mkl_rt.2.dll
svml_dispmd.dll
mkl_intel_thread.2.dll

These DLLs are part of the Intel Fortran and Intel MKL runtime stack and normally come either from Intel oneAPI redistributables or are bundled/linked in a way that they do not need to be installed manually by the end user. The current behavior effectively requires the user to separately install Intel runtimes or to hunt down these DLLs, which breaks a clean pip install xara experience on Windows.

Could you please:

Confirm whether xara is expected to ship with these Intel runtime dependencies (or use a different BLAS/LAPACK backend) on Windows, and

If so, adjust the Windows wheels or packaging so that the required runtimes are either:

bundled correctly in the wheel, or

declared as proper dependencies with clear installation instructions,

so that a standard pip install xara on Windows results in a working installation without missing-DLL errors?

Thank you
