uClibc Compatibility Shim for Ingenic Libraries

Overview

This project provides a compatibility shim to enable Ingenic libraries, such as libimp, to work seamlessly with the uClibc compiler. It serves to bridge compatibility issues and facilitate the development of applications on Ingenic platforms using uClibc as the standard C library.

Features

• Compatibility layer for Ingenic libraries to work with uClibc
• glibc ctype table emulation (__ctype_b_loc, __ctype_tolower_loc, __ctype_toupper_loc)
• pthread cancel/unregister stubs
• mmap offset fixup for Ingenic memory mapping
• 64-bit file operation wrappers (fopen64, open64, fseeko64, mmap64)
• Supports both xburst1 (T10-T32) and xburst2 (T40/T41) platforms

Getting Started

Prerequisites

• An Ingenic-based platform
• A uClibc cross-compiler toolchain

Building

Build as a shared library:

${CROSS_COMPILE}gcc -fPIC -shared -o libuclibcshim.so uclibc_shim.c

Usage

Link your application with -luclibcshim alongside the Ingenic SDK libraries:

LDFLAGS += -limp -lalog -lsysutils -luclibcshim

The shim provides missing symbols that the Ingenic SDK expects from glibc but are not present in uClibc.
