[Gumstix-users] Cross compilation error in gumstix based mobile robots

[Muratkrty <mur...@gm...>]

Hi,

We have  several Khepera III mobile robots  in our laboratory which has
following specifications 
with gumstix platform[1]:
* Linux OS, Angström distribution (OpenEmbedded tools),
* kernel 2.6.24

To get signal information from existing nodes in ad-hoc network,  we have
found a bash command (iw) to get these information,In order to run this
command in the robots, we have just tried to compile the source code via
cross compiler (arm-angstrom-linux-gnueabi-gcc)[2].

Cross compilation generates no error in PCs and it generates expected
outputs, yet we faced below errors while trying execution of the compiled
command in robots.

*--PC and Robot's kernels versions---*
Kernel PC#1: 3.8.0-19-generic 
Kernel PC#2:  2.6.24
Kernel Robot: Linux korebot2 2.6.24 
*--------------------------------------------------*

*--Error while executing PC#1's file in robot-*
$ dev eth0 scan
./iw: ./iw: 1: Syntax error: "&" unexpected (expecting ")")
*------------------------------------------------------------*

*--Error while executing PC#2's file in robot---*
$ ./iw dev eth0 scan 
./iw: ./iw: 1: Syntax error: Bad function name
*---------------------------------------------------------------*

Please note that we have also changed default PC shell to /bin/sh which is
same with the robot's shell, yet same errors.

Any ideas to fade away these errors?
