Question

Looking for help compiling my program below. I’m getting a “***Stop. no Targets.” error when typing in limit.makefile in the compiler buffer. Ideas?

int main(int argc, char *argv[]) {
  struct rlimit limit;

  limit.rlim_cur = 60000;


limit.rlim_max = 60000;

if (setrlimit(RLIMIT_FSIZE, &limit) == -1){
    perror("Error preventing core dump, errno=%d\n", errno);
    exit(1);
  }

else {
    printf("The current core limit is %ll.\n", limit.rlim_cur);
    printf("The core max limit is %ll.\n", limit.rlim_max);
    exit(0);
  }

  if (getrlimit(RLIMIT_FSIZE, &limit) == -1){
    printf("getlimit() failed with errno=%d\n", errno);
    exit(1);
  }


}

Compile command: make -k -f limit.makefile
This is what I type for the compiler buffer….still get the error though.

Makefile:

CC = /usr/bin/gcc
CFLAGS = -g -Wall -std=c99 -O2 -arch x86_64

Just tried that make -k -f myfile on an empty file and got your error.

If you just want it to work

CC= /usr/bin/gcc 
CFLAGS = -g -Wall -std=c99 -O2 -arch x86_64



all: test.c
    $(CC) $(CFLAGS) test.c

Note that the tab under all has to be a “real” tab.

I recommend you check out a makefile tutorial or just compile it from the command line.
gcc -g -Wall -std=c99 -O2 -arch x86_64 limit.c

BTW, not sure about that -arch flag. Not valid on my Linux box.
