Link error: Failed to open external module

Question

Newbie question #2... I'm in chapter 5 of the tutorial, just added the button to calculate min and max values of the sinewave. I get two link errors when I try to run the program.
2 Project link errors:
 Failed to open external module
 Failed to open external module
If I comment out the MaxMin1D function and fudge the min and max values the program runs.
Any ideas?
The function I added is as follows which appears  to be identical to the sample in the tutorial.
int CVICALLBACK FindMaxMin (int panel, int control, int event,
        void *callbackData, int eventData1, int eventData2)
    ssize_t min_index;
    double min;
    ssize_t max_index;
    double max;
//    max = 5;
//    min = 3;
    switch (event)
        case EVENT_COMMIT:
            MaxMin1D(sine, 100, &max, &max_index, &min, &min_index);
            SetCtrlVal(panelHandle, PANEL_MAX, max);
            SetCtrlVal(panelHandle, PANEL_MIN, min);            
            break;
        case EVENT_RIGHT_CLICK:
            break;
    return 0;

Answer 1

I searched for analysis.h, found it and copied it to the same folder as sample1.c and the program now links and runs.
I'm wondering if I'm missing something in the configuration (not smart enough to know where to search)???
Thanks
