Can't use C libraries to read images or excel files in Cyclone V project

I am struggling in using the libraries of C-language in the ARM development studio IDE version 2021.1 (Intel edition). Let me demonstrate the working environment as follow:

1) Hardware: "ARM Cyclone V SoC FPGA development kit".

2) Software: licensed copy of the ARM development studio IDE version 2021.1 (Intel edition).

3) Windows 10 OS.

4) JTAG connection between the FPGA kit and the PC.

5) Coding: "C".

6) Compiler: ARM6.

7) I am trying to utilize the "stb_image.h" library to read an image in the attached project.

After building the project, the error message is prompted in the console view, please refer to the snapshot below.

I am wondering please, why the system didn't find the header file although it is uploaded to the project files? This problem also happened with other types of C-libraries, to read an excel file for example, any idea please?

    Hi,


    In your calendar.c, can you define as below and re-try:


    #include <stdio.h>

    #include <stdlib.h>

    #define STB_IMAGE_IMPLEMENTATION

    #include "stb_image.h"

    #define STBI_NO_SIMD

    • Please replace the .h files with below .h files:

    https://github.com/nothings/stb


    • Do make clean.


    • Place the 3 files same directory your Makefile.


    • Include as below in calendar.c

    #include <stdio.h>

    #include <stdlib.h>

    #define STB_IMAGE_IMPLEMENTATION

    #include "stb_image.h"

    #define STBI_NO_SIMD


    • Then Build Project

      Hi

      I followed your steps strictly. I think the compiler read the "stb" library successfully. But I got another kind of error as you can see below:

      According to the ARM website that you shared, the problem is in the scatter file. However, the project is imported from the workspace of the DS software and it doesn't have a scatter file. Secondly, even if there is a scatter file, what kind of modification should be made on it? thanks for your support

    Hi,


    Regarding the error, I suggest that you go into the ARM website/support forum section for that specific issue.
