xmmintrin.h: No such file or directory

This error message indicates that the compiler is unable to find the "xmmintrin.h" header file, which is a part of the Intel Intrinsics library. This library provides low-level functions for SIMD operations on x86 processors.

To resolve this error, you need to ensure that the Intrinsics library is installed on your system and that the compiler is configured to include its header files. You may also need to specify the path to the Intrinsics library in your compiler settings.

If you are using a Linux-based system, you can install the Intrinsics library by running the following command:

sudo apt-get install gcc-multilib

This command will install the necessary libraries and header files for compiling programs that use the Intrinsics library.

If you are using a different operating system or compiler, you may need to refer to the documentation for your specific setup to determine how to install and configure the Intrinsics library.
