SubjectKernel Installer
Hello everyone , :

i have been writing a kernel installer which may make the kernel
installation process a lot more easier for noobs , (don ask me why
noobs would like to compile a kernel) , but atleast till they learn
to do it the good way !

i have written some code which is below , well i am stuck at one thing , ...
once the .config file is set , is there any method to compute the
exact no of files that are going to be compiled ??
lack of this knowledge is clearly visible in the use of a "while(1)"
in the code below :



#include <stdio.h>


int main(int argc, char * argv[]) {
char buf[100],syscommand[100];
FILE *fp;
int i=0,j=0,k=0,l=0;
int checking_done=0;
strcpy(buf,"\0");

fflush(stdout);

strcpy(syscommand,"make -C ");
if(argc==2){
strcat(syscommand,argv[1]);
}
else{
printf("The program accepts the kernel source \n directory as
the single argument.\n Please provide necessary arguments\n");
return ;
}


printf("\n\n\t\t\t\t\t\t Kernel Installer V1.0\n\n ");


fp= popen(syscommand,"r");
do{
fscanf(fp,"%s",buf);

if(checking_done!=1){
if(strcmp(buf,"CHK")==0){
fscanf(fp,"%s",buf);
printf("\rChecking file : %-30s\t\n",buf);

}
if(strcmp(buf,"CALL")==0){
fscanf(fp,"%s",buf);
printf("\rCalling script : %s\t\n",buf);

}
}
if(strcmp(buf,"LD")==0){
fscanf(fp,"%s",buf);

printf("\rLinking File : %s\t",buf);
l++;
checking_done=1;

}
if(strcmp(buf,"CC")==0){
fscanf(fp,"%s",buf);
if(strcmp(buf,"[M]")==0){
fscanf(fp,"%s",buf);
printf("\rCompiling module (%-4d files, %-4d
modules compiled): %-60s\t",i,l,buf);
l++;
}
else
printf("\rCompiling (%-4d files, %-4d
modules compiled) : %-60s\t",i,l,buf);
i++;
switch(i%4){
case 0:
printf(" | ");
break;
case 1:
printf(" / ");
break;
case 2:
printf(" - ");
break;
case 3:
printf(" \\ ");
break;
}
for(k=0;k<j;k++)
printf("=");
printf(">");
if((i%100)==0 && i!=0){
j++;
}
checking_done=1;

}
fflush(stdout);
}while(1);
pclose(fp);
return 0;

}
there is some more work that i remain to add, like being able to start
from the kernel source , that is just provide the path to the archive
and it does everything else and so on ,
but for now i am stuck here !

Thanks
Satish
