[技術] 各家Toolchains的比較
Written on 4:04 下午 by Yu Lai
一般而言，
在開發Embedded System時大都需要用到不同平台的cross-compiler與Toolchains。
而在elinux.org有一篇介紹各家Toolchains的文章，就轉來參考囉。
Ref: http://elinux.org/Toolchains
以下是常見的幾個Toolchains的說明:
CodeSourcery
CodeSourcery develops Sourcery G++, an Eclipse based Integrated Development Environment (IDE) that incorporates the GNU Toolchain (gcc, gdb, etc.) for cross development for numerous target architectures. CodeSourcery provides a "lite" version for ARM, Coldfire, MIPS, SuperH and Power architectures. The toolchains are always very up to date. CodeSourcery contributes enhancements it makes to the GNU Toolchain upstream continually, making it the single largest (by patch count) corporate contributor.
DENX ELDK
The DENX Embedded Linux Development Kit (ELDK) provides a complete and powerful software development environment for embedded and real-time systems. It is available for ARM, PowerPC and MIPS processors and consists of:
Cross Development Tools (Compiler, Assembler, Linker etc.) to develop software for the target system.
Native Tools (Shell, commands and libraries) which provide a standard Linux development environment that runs on the target system.
Firmware (U-Boot) that can be easily ported to new boards and processors.
Linux kernel including the complete source-code with all device drivers, board-support functions etc.
Xenomai - RTOS Emulation framework for systems requiring hard real-time responses.
SELF (Simple Embedded Linux Framework) as fundament to build your embedded systems on.
All components of the ELDK are available for free with complete source code under GPL and other Free Software Licenses. Also, detailed instructions to rebuild all the tools and packages from scratch are included.
The ELDK can be downloaded for free from several mirror sites or ordered on CD-ROM for a nominal charge (99 Euro). To order the CD please contact office@denx.de
Detailed information about the ELDK is available here.
Buildroot
Buildroot is a complete build system based on the Linux Kernel configuration system and supports a wide range of target architectures. It generates root file system images ready to be written to flash. In addition to having a huge number of packages which can be compiled into the image, it also generates a cross toolchain to build those packages from source. Even if you don't want to use buildroot for your root filesystem, it is a useful tool for generating a toolchain. It should be noted however that it only supports uClibc. If you want to use glibc, you'll need something else.
