Compiling C for Kobo aura H2O

[EtiennePasteur]

Hi everyone,

I'm actually trying to figure out how to cross-compile C/C++ code for my Kobo aura H2O running on Linux 2.6.35.3.

I'm trying to compile a custom busybox to disable rtcwake sanitation (cf: https://www.mobileread.com/forums/sh...=212145&page=4)

First of all, I want to be able to run a simple helloworld program on my Kobo.

#include <unistd.h>

int main(int ac, char **av) {
  write(1, "Hello world\n", 12);
  return 0;
}

I have downloaded the gcc-linaro-arm-linux-gnueabihf toolchain on the Kobo-Reader repository and also the Kernel 2.6.35.3 (cf: https://github.com/kobolabs/Kobo-Reader)

After that I'm able to compile my helloworld without any issues by :

cd ~/gcc-linaro-arm-linux-gnueabihf-4.8-2013.04-20130417_linux/bin
./arm-linux-gnueabihf-gcc -I ~/linux-2.6.35.3/include/ -o helloworld helloworld.c

But when I'm trying to execute my helloworld on my Kobo I'm always getting a Segmentation Fault. Or when I compile it in static with the -static flag I'm getting an Illegal instruction .

I don't understand what I'm doing wrong. Can somebody give me some clues ?

Thanks.

How are you executing the program? Over SSH, with fmon, in a init file, etc?

I find out why ...

I sent my executable over ftp with FilleZilla who is choosing ASCII as transfer mode.

After sending it over USB or using ftp command line, it finally works

Thanks anyway !
