imx7-warp7 cross compiler

[bheemarao]

I am executing the below steps using imx7 warp7 board:
i have ported "core-image-machinetest" image into it and trying to cross compile a simple helloworld.c program into it.

i have installed arm-poky-linux-gnueabi-gcc from meta-toolchain and it is installed in /opt/poky/1.xx

i have created helloworld.c

#include <stdio.h>
int main (int argc, char **argv)
{
printf("Hello world !\n");
return 0;
}

and compiled using
$ arm-poky-linux-gnueabi-gcc -o helloworld helloworld.c

i was able to create executable file and tested the type also

$ file hello-world
hello-world: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.16, not stripped

but when executing on the target it is giving the below error

root@imx7s-warp:/usr# ./helloworld
-sh: ./helloworld: No such file or directory

have anybody faced similar issues.

is there any steps i have missed out or is there any procedure to be followed either in standalone or while yocto development package compile.

Hi Bheema,

you are not passing any arguments when calling ./helloworld

have you tried?

#include <stdio.h>
int main ()
{
    printf("Hello world !\n");
    return 0;
}

Regards,
Carlos

the issue got resolved by compiling the helloworld.c as shown below:

$ bitbake meta-toolchain

bheema@Bheema:~/fsl-warp7-yocto/build-x11-machine-test$ /home/bheema/fsl-warp7-yocto/build-x11-machine-test/tmp/deploy/sdk/poky-glibc-x86_64-fsl-image-machine-test-cortexa7hf-neon-toolchain-2.1.2.sh
toolchain gets install at /opt/poky/2.1.2

and while compiling for target warp7 board we have to follow below steps:

root@Bheema:~/warp_appln# source /opt/poky/2.1.2/environment-setup-cortexa7hf-neon-poky-linux-gnueabi

root@Bheema:~/warp_appln# ${CC} helloworld.c -o helloworld.out
