请达人指点:建立交叉编译环境问题

hexl

在红帽子9.0下安装cross-2.95.3,设置好path环境变量.测试编译arm-boot-1.1.0文件:
make smdk2410_config
然后 make   编译成功

测试编译u-boot-1.1.4文件:
make smdk2410_config
然后 make   则编译失败.出错信息如下
.......
strip bmp_logo
./bmp_logo logos/denx.bmp >/usr/local/arm/u-boot-1.1.4/include/bmp_logo.h
make[1]: Leaving directory `/usr/local/arm/u-boot-1.1.4/tools'
make -C examples all

make[1]: *** [hello_world.o] Error 1
make[1]: Leaving directory `/usr/local/arm/u-boot-1.1.4/examples'
make: *** [examples] Error 2

不知道是什么原因引起的,请达人指点.
另外下载安装了eldk3.2.2交叉编译器,编译uboot和上面错误基本一样!

难道我的问题太简单，大家都不屑回答吗?
我是个新手，请各位多多帮助!

用百度搜索“cc1: Invalid option `abi=apcs-gnu'”
其中一个链接为：郭步高的第一个BLOG

以下是他的解决方法，但是我没试过（！）你可以试试，或者找找其他链接。
如果还是不行就用google搜索。

u-boot移植过程中abi=apcs-gnu问题的解决

以下摘自 http://sourceforge.net/mailarchive/message.php?msg

That's true but the cc-option checker should use -mapcs-32 if it is
available, otherwise it will fall back to -mabi=apcs-gnu. It looks
like your compiler doesn't support the first option either. In this
case, I'm not sure it worked before Peter's patch. What CPU is it?

You could try the following in your config.mk but you should
investigate why -mapcs-32 doesn't work:

PLATFORM_CPPFLAGS +=＄(call cc-option,-mapcs-32,＄(call cc-option,-mabi=apcs-gnu,))

我使用的GCC为 arm-linux-gcc-3.4.1.tar.bz2
有效！

谢谢这位兄弟了。问题解决了，就是这个原因
