请教高手:can't execute binary file

sithui

我在2410上跑PPP时出现如下错误信息
请知情人士给我指点指点,问题到底出在哪里
我用的是2.4.18核 用2.95.3编译的,文件系统是从9200移过来的ramdisk
启动信息如下:

[root@AT91RM9200DK /root]$
cd到/usr/sbin目录下开始运行ppp:
[root@AT91RM9200DK sbin]$pppd
bash: /usr/sbin/pppd: cannot execute binary file
[root@AT91RM9200DK sbin]$pppd
bash: /usr/sbin/pppd: cannot execute binary file
[root@AT91RM9200DK sbin]$pppd
前面两次提示说cannot execute binary file
第三次运行就一直没有响应,跟死机了一样,但核心板上指示灯还是正常的闪
内核起来时有一个Warning: bad configuration page, trying to continue,不会和这个有关吧? 还是少了哪个模块?我的ppp是2.4.1的

请各位给点提示啊~~~谢谢!!!!

tcz

cannot execute binary file
不能处理二进制文件。
没遇到过，估计是该可执行文件格式问题……

sithui

谢谢tcz的关注,文件格式会有什么问题呢?
我看了一些资料,问题可能是缺少模块
但具体少了什么就不知道了...

xkqian

用的交叉编译工具有问题，查看自己的编译过程，看是不是中间采用了linux自带的编译器

bucketxp

嵌入式中出现这个错误的最常见的原因就是你的可执行程序不是用交叉工具链编译生成的。
你在主机环境中realelf一下那个pppd，看看的体系解构是不是ARM的。
reaelf pppd -h

sithui

不对啊,我用的是gcc-2.95.3编译的.它是三星2410提供的交叉编译器
#make menuconfig

#make ARCH=arm CROSS_COMPILE=/../2.95.3/bin/arm-linux- zImage

#./mkimage2410 uImage
生成了uImage文件
我想这样做没有错吧
这几天了都搞晕我了,大家还有什么意见发表一下啊,谢谢了!
谢谢xkqian和bucketxp两位的指点~~!

sithui

我在想是不是我用的9200下面的文件系统造成的.
我用我自己为2410做的文件系统加载时出现如下错误:
EXT2-fs warning: checktime reached, running e2fsck is recommended
VFS: Mounted root (ext2 filesystem).
Mounted devfs on /dev
Freeing init memory: 68K
==> 1
init: error Khile loading shered libraries: rannot open sharnd object file: eany panic: Attempted to kill init!


好像文件系统加载上去了但是库文件出了问题导致init 进程失败,不知道我这样理解对不对.
还请各位多多指教!

下面的错误信息:

init: Klib/libc.so.6: eersion `GLIBC_2.2' not found (rrquired by init)

可能真的是库文件不对
希望各位不吝赐教!

bucketxp

可能你的文件系统的busybox或者shell不是用的静态编译（static），所以在执行init的时候会说找不到库，把busybox或者shell编译成静态的在试试看。
