IRIX 64-bit makefile
File type: Various data file
The .irix64bit file is a text makefile for building software on 64-bit versions of the SGI IRIX operating system.
It contains instructions for the IRIX make utility, including build targets, dependencies, and commands.

IRIX was a Unix operating system developed by Silicon Graphics, Inc. The .irix64bit file extension identifies a makefile intended for the 64-bit IRIX environment.
The file normally describes how source files are compiled and linked, and which files must be rebuilt when source files change. It is a build-control file rather than a document or general-purpose data format.
IRIX makefiles were used on compatible SGI systems. IRIX is discontinued, so this extension is now mainly encountered in older software source trees and archived development environments.
Open the .irix64bit file in a text editor to inspect its build instructions. On an IRIX system, use the IRIX make utility with the file as its makefile.
Because the file contains shell commands and build rules, it should be used only with source code and tools that match its original IRIX environment. Other Unix make implementations may require changes for compatibility.
There is no standard converter for an .irix64bit file. A makefile is a set of platform-specific build instructions, so conversion to another build system normally requires manually rewriting its rules.
The file can be retained as plain text or renamed for use with a compatible make workflow, but renaming alone does not convert its commands or dependencies.
