I am working on cross development toolchain. I used packages binutils-2.10.1, gcc-2.95.3, glibc-2.2.4, glibc-linux-threads-2.2.4, kernel-2.4.17. (most common packages for building toolchain)

I followed book “Building Embedded Linux Systems (OReilly 2003) – chapter 4″ and finally i am able to compile all the above packages without any errors and did everything till section 4.2.7.

I was not able to understand section 4.2.8 (something related to makefile), is it important ? and how can i check whether I have successfully build a working toolchain.

One more thing, I wrote a hello world program, and compiled it with
#arm-linux-gcc 1.c
it created a a.out file without any errors. Does this signifies that i have successfully build a working toolchain ? because I can’t run a.out file on my host, I need a target system to run a.out on it.

fseek(fptr,0,SEEK_END);
ret2 = ftell(fptr);
ch =(char *) malloc(ret2);
fseek(fptr,0,SEEK_SET);
printf(“\n%d bytes of data is present in the file\n”,ret2);
ret = fread(ch,1,ret2,fptr);
printf(“\nData in File :\n%s”,ch);
printf(“\nNo of Characters read from File : %d”,ret);
printf(“\n\n”);
return 0;
}

Code is working fine… but the problem is it still works with

ch =(char *) malloc(1);

Why ???
