"Undefined symbol: float" error when compiling for ti83p

[asdfezxcas]

Evening,

I've been brushing up on C and trying to write some programs for the TI84 plus. I've been able to get some basic programs working, but right now I'm having trouble compiling the following program. I'm not sure if the issue is in something I'm doing, an issue with my installation of the compiler, or the compiler itself. I'm on Ubuntu, and I'm using version 23064-e05ec48f33-20250103 downloaded through snap.

This is the code in question:

Code: Select all

#pragma string name CIRIDC
#include <stdio.h>

//prototypes
void paraRes();
void curDiv();
void voltDiv();

//selects program to run
int main(){
    char choice;

    printf("1.ParaRes\n2.CurDiv\n3.VoltDiv\n");
    choice = getkey();
    switch(choice)
        {
        case'1': paraRes();
        break;
        case'2': curDiv();
        break;
        case'3': voltDiv();
        break;
    }

    return 0;
}

//parallel resistor (or parallel inductor, OR series capactior)
void paraRes(){
    float denom;
    float temp;
    float equiv;
    int count;

    printf("Parallel Resistors\nCount:");
    scanf("%d", &count);

    for (denom = 0; count > 0; count-- )
    {
        printf("R:");
        scanf("%f", &temp);
        denom = denom + (1/temp);
    }

    equiv = (1/denom);

    printf("Equiv:\n%f",equiv);

}

//current divider over parallel resistors
void curDiv(){
    int count;

    printf("Current Divider\nCount:");
    scanf("%d", &count);
}

//voltage divider over series resistors
void voltDiv(){
    int count;

    printf("Voltage Divider\nCount:");
    scanf("%d", &count);
}

This is the command I'm using to compile the code:

Code: Select all

z88dk.zcc +ti83p -o build/code.bin -create-app ciridc.c -subtype=asm

This is the error I'm getting:

I believe it has to do with the floats in the paraRes function. I can get the program to compile with that function's contents dummied out, but of course that's not very useful. Any advice would be much appreciated. Thanks!

You need to select a maths library to use: https://github.com/z88dk/z88dk/wiki/Cla ... -Libraries

Try adding -lm to your command line.
