You can have a look at the ecos manual (http://www.ecoscentric.com/ecospro/doc/html/user-guide/index.html) and especially chapter 2, "programming with eCos". It shows how to compile sample applications, and from there you can compile your own.

I work on the ecos operating system, I want to run it on the virtual machine qemu (pc_rltk8139: architecture x86), I downloaded and installed then I started with a small code c "Hello word", which Has worked well. 

 Then, I develop a code c on the synthetic Linux target (Ubuntu). All the code that I created in c works well on ubuntu, i tried to do the same work on my qemu machine and transferred it to ecos wich it did not work. My code includes a copy program that requires loading data from two text files. An input file(entree.txt) contains data that will be copied to the other output file(sortie.txt). My problem is that I do not know how to integrate my files into an appropriate file system image and how to integrate it into the eCos image.  Code c: # include <stdio.h> # include <stdlib.h> # define ENTREE "/home/amine/ecos/eCos-on-QEMU/entree.txt" # define SORTIE "/home/amine/ecos/eCos-on-QEMU/sortie.txt"  int main(void) {  FILE *f_in, *f_out;  int c;    if ((f_in = fopen(ENTREE,"r")) == NULL)  {  fprintf(stderr, "\nErreur: Impossible de lire le fichier 111 %s\n",ENTREE);  return(EXIT_FAILURE);  }  if ((f_out = fopen(SORTIE,"w")) == NULL)  {  fprintf(stderr, "\nErreur: Impossible d'ecrire dans le fichier 222 %s\n",  SORTIE);  return(EXIT_FAILURE);  }  while ((c = fgetc(f_in)) != EOF)  fputc(c, f_out);  printf("copie correcte\n");  fclose(f_in);  fclose(f_out);  return(EXIT_SUCCESS); }  output message : Erreur: Impossible de lire le fichier 111 /home/amine/ecos/eCos-on-QEMU/entree.txt  issue : how to port files to ecos  waiting for your guidance. thank you

This forum is about Altera components, and you can find a few people that can help with the Nios 2 port of eCos, but I'm afraid I don't have any experience with the i386 version. You'll probably have to look for an eCos generic forum instead of this one.
