While "cctools" is a common package name, the specific version number 65 corresponds to the Apple cctools (the toolchain used for Darwin/macOS, often used in cross-compilation toolchains like osxcross). cctools 65 top
Here are the details regarding the "paper" or documentation you are looking for:
cctools is a collection of low-level macOS and iOS development utilities originally created by Apple and maintained in various forks; “cctools 65” refers to a specific release or version series (release number 65) of those utilities. The suite includes assembler/linker-related tools, object-file utilities, and helpers used when building, linking, inspecting, and manipulating Mach-O binaries and related build artifacts on Apple platforms. The most commonly encountered utilities in cctools include ld, strip, otool, ar, nm, and others tailored for Mach-O and Apple runtime conventions. Standard Ethernet caps at 100 meters (328 feet)
cctools (C Compiler Tools) is a critical open-source package that provides the low-level binary manipulation and analysis tools for Apple platforms (macOS, iOS, watchOS, tvOS). It includes the linker (ld), the static library archiver (ar), and object file inspection tools (otool, nm, lipo).
This report focuses on two distinct components: While "cctools" is a common package name, the
Crucially, top is not a direct component of the cctools package. However, it relies on the same underlying Mach-O binary format and kernel APIs (task_info, proc_pidinfo) that cctools manipulates. Therefore, understanding cctools enhances the interpretation of top’s output.
For the uninitiated, cctools is a collection of binary utilities used for manipulating object files. While it sounds obscure, it is effectively the bridge that allows developers to compile code for Apple platforms (macOS, iOS, tvOS) on operating systems where Xcode doesn’t exist—most notably Linux and Windows.
The suite includes critical tools such as:
