Hello Henderson,
Thank you for that lead, I changed the code by reading through the code
mentioned at
https://www3.ntu.edu.sg/home/ehchua/programming/cpp/gcc_make.html#zz-2.1
Now created the sample example and did the following
**********
// hello.c
#include <stdio.h>
int main() {
printf("Hello, world!\n");
return 0;
}
**********
Make file with the below contents:
***************
all: hello.exe
hello.exe: hello.o
gcc -o hello.exe hello.o
hello.o: hello.c
gcc -c hello.c
clean:
rm hello.o hello.exe
****************
Ran the build withe the make file using the below command:
******************
root at ip-172-31-24-96:/data/cprg# ls
hello.c makefile
root at ip-172-31-24-96:/data/cprg# pump make -j8 CC=distcc --debug
__________Using distcc-pump from /usr/local/bin
__________Found 2 available distcc servers

******************
So here it looks like it has build correctly, But I'm yet to ascertain, If
all the servers were really used during the compile operation which lands
me back to the original question.
Thank you,
Anish
