J784S4XEVM: Error statement when compiling a Linux app

TAEHO KIM

Part Number: J784S4XEVM

When compiling, an error occurs because the tivxInit and tivxHostInit functions cannot be found, 
as shown below.

Where should I link the lib file?

Hi Kim,

Can you follow the steps mentioned in the docs for the build setup,

https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/latest/exports/docs/vision_apps/docs/user_guide/BUILD_AND_RUN.html

I am developing a new Linux app using VS Code instead of building the code provided by TI directly.

I need to link the ".a" file containing the body of the `tivxInit' and 'tivxHostInit' functions, but I can't find which file it is.

I found the location of "\ti-processor-sdk-rtos-j784s4-evm-11_02_00_06\tiovx\source\platform\board\common\tivx_init.c",

which contains the source code for the `tivxInit' and 'tivxHostInit' functions, but I cannot find the name of the library that is built from this file.
