# Implementing the Intel Decimal Library for MacOS and Linux

Due to the malleability of the many Linux distributions including MacOS, Interactive Brokers is unable to provide a pre-built binary for the library. As such, users programming in C++ on a Linux machine must manually build the Intel® Decimal Floating-Point Math Library manually.

As described in the README file from the linked page, you can find the library's build steps within the \~/IntelRDFPMathLib20U2/LIBRARY/README file.
