armnoneeabigcc

armnoneeabigcc is a cross-compilation toolchain name used in some Linux distributions and embedded development environments to refer to a GCC-based cross-compiler for ARM targets that use the ARM Embedded Application Binary Interface (EABI) and operate in big-endian mode. It is typically part of a package that provides the compiler, assembler, linker, and runtime libraries configured for bare-metal ARM development (no operating system).

The naming suggests a variant of the common arm-none-eabi toolchain with a big-endian data layout, often achieved by building with -mbig-endian or by a packaging convention that includes big-endian in the target description. The exact name and availability are not standardized; some distributions expose a dedicated armnoneeabigcc binary or package, while others provide arm-none-eabi-gcc with appropriate endianness flags. Projects may use it to compile C and C++ code intended to run on microcontrollers or other ARM-based devices without an operating system.

In practice, armnoneeabigcc is typically used alongside binutils and a C library such as newlib, and may be paired with debugging tools like GDB. It is one option among ARM toolchains derived from GCC, with availability varying by platform and distribution. Users encountering this name should check their package manager’s documentation to confirm the exact target triplet, endianness configuration, and accompanying tools, since the naming can reflect packaging conventions rather than a single standardized standard.
