Xilinix to Quartus "Library Conversion"

Hi all,

I have a library written by one of my ex-colleague for Xilinix ISE, It basically converts ML algorithms to HLS, Now I want to convert this library for Altera Fpga. I have used Altera Fpga/Quartus in different projects but I have no experience with developing libraries for Quartus environment. I need guidance how should I proceed and which particular segments are needed to be changed for Altera in general. Because same library is not working when i run my project. Please find the attachment.

Thank you.
