关于arm-elf-tools和arm-linux-toolchain的区别

xiaxiuqiu

我在应用的一个程序
在readme中介绍可以用arm-linux-toolchain来编译
在arm中运行
而我想把这个程序移植到uclinux
在uclinux中用的是arm-elf-tools
我试图用arm-elf-tools对源程序进行编译
但出现了错误
我不清楚错误是否是因为用了不同交叉编译工具导致的
想请大家帮忙看一下
我是一个新手
不太清楚在不同的交叉编译工具是否可以完成
如果不可以的话，那么移植的工作应该怎样进行呢
谢谢！

下边是编译最后一段的信息：

这不是编译器的问题,是源代码的问题,
检查一下__CTOR_LIST__和__DTOR_LIST__有没有在头文件里定义.

查了些资料
问题解决了
在makefile中添加了-elf2flt
源程序在linux下是可以运行的
接下来出现了新的error
非常感谢您的回复

我下载了ppp-2.3.4,试了一下,可以成功编译,不过编译前要执行两条命令

export CC=arm-elf-gcc
export LD=arm-elf-gcc -Wl -elf2flt

arm-elf-tools -v,让我看看结果。
