关于为 Xscale ARM 构建交叉编译器的建议?
我正在使用 PXA270 Xscale 开发板(类似于 Gumstix)，并提供了一个交叉编译器，但它是 GCC 3.3.3.我想学习如何构建我自己的交叉编译器，这样我就可以自定义设置，但是很难让 crosstools 和 crosstools-ng 成功构建工具链.我的主要需求是使用 GCC 4.2.X 和使用软浮动的能力.我正在运行 Ubuntu 9.有没有人对为这样的系统构建工具链有任何建议或建议?
I am playing around with a PXA270 Xscale development board (similar to the Gumstix), and was provided a cross compiler, but it is GCC 3.3.3. I would like to learn how to build my own cross compiler, so I can customize the setup, but have had trouble getting crosstools and crosstools-ng to successfully build a toolchain. My main needs are using GCC 4.2.X and the ability to use soft float. I am running Ubuntu 9. Does anyone have any recommendations or advice on building a toolchain for such a system?

www.gnuarm.com 有说明，用于构建您自己的 ARM 交叉编译器以及可用于 下载.他们那里没有 GCC 4.2.x，但我使用与这些说明非常相似的步骤构建了它，没有太多问题.
www.gnuarm.com has instructions for building your own ARM cross compiler as well as binaries available for download. They don't have GCC 4.2.x there, but I've built it using steps pretty similar to those instructions without too many problems.
为什么需要软件浮点数?它会非常缓慢；大多数应用程序只需要使用定点实现(读取:整数).
Why do you want software floating point? It's going to be really slow; most applications only really need to use a fixed point implementation (read: integers).
