Pset5 load clang error: linker command failed with exit code 1

Question

I have been working on the load function for pset5 for more than 2 weeks and I am keep receiving clang error: linker command failed with exit code 1. Bellow I have the code so everyone can take a look at it and the error message. Can someone please give me a guidance on where the problem seems to be hidden? Thank you

bool load(const char* dictionary) {

node *head=NULL;
FILE *fp=fopen(dictionary, "r");

if (fp==NULL)
{
    fprintf(fp,"File dictionary could not be opened.\n");
    return false; 
}

while (!feof(fp))
{
    node *new_node=malloc(sizeof(node));
    fscanf(fp, "%s", new_node->word);
    int h=hash_function(new_node->word, strlen(new_node->word));

    if (hash_table[h]==NULL)
    {
        hash_table[h]=new_node;
        head=hash_table[h];
        head->next=NULL;
    }
    else if (hash_table[h]!=NULL)
    {
        new_node->next=head->next;
        head->next=new_node;
    }
}

if(feof(fp))
{
    return true;
    fclose(fp); 
}

return false;
fclose(fp);

}

You are trying to write to a NULL file pointer

if (fp==NULL) { fprintf(fp,"File dictionary could not be opened.\n"); return false; }

Change fprintf function to a printf function then it should work
