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
