Problem building hello APP.

[glodone]

Hi all,

I loaded the kernel and rootfs from esky.
I build a hello app which prints "hello" with gcc-4.3.2
When I put it in mini2440 and try to run it then it gives me a "Segmentation Fault".
Never before got this.

How can it be resolved.


Thanks,
Guillermo.

This is the app code:

File: main.c

Code: Select all

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char** argv) {
    printf( "hola\n" ) ;
    return (EXIT_SUCCESS);
}

Code: Select all

arm-linux-gcc -o hello main.c

ANOTHER THING I SAW
I downloaded from angstrom the gdb and tried to execute it.
Then it gave me "Illegal Instruction".
So I downloaded the libc6 from angstrom. (Install it)
and then the gdb worked.
But not the hello app.


GDB output

Code: Select all

Hi,
I get the same problem but if I run the same object in buserro-angstrom distribution I have no problem so I'm sure the application is well compiled.

Even I am getting same issue with my hello.bin
It gives me error

[root@FriendlyARM sbin]# ./hello.bin
-sh: ./hello.bin: not found
[root@FriendlyARM sbin]#

Don't know whats wrong.
I have raised a separate post with Topic :- " Simple Linux Hello word exe is NOT executing on mini2440 3.5 "

Hope some one is there to help.

Thanks
