ESP HFP API Build Error - Undefined reference to ... (IDFGH-2834)

searock35 commented 4 years ago

Environment

Development Kit: ESP32-DevKitC
Kit version (for WroverKit/PicoKit/DevKitC): v2
Module or chip used: ESP32-WROOM-32
IDF version (run git describe --tags to find it): Master
Build System: idf.py
Compiler version (run xtensa-esp32-elf-gcc --version to find it): 8.2
Operating System: Windows
(Windows only) environment type: ESP Command Prompt
Using an IDE?: No
Power Supply: USB

Problem Description

I am trying to use the HFP AG API that was recently added. I have written some code that begins to implement the API but I can't get the file to build properly. When I build, It fails on the "linking CXX executable" stage for the elf file. It says that there are undefined references to the functions I reference from the esp_hf_ag_api.h file.

Expected Behavior

I expect the program to build properly.

Actual Behavior

It fails during the build on the "Linking CXX Executable" part. See log below.

Steps to reproduce

Include references to the esp_hf_ag_api file and attempt to build the project.
See the error unfold

(I'm really sorry, I don't know how to link or attach my project files or logs here. Please ask me for more stuff when you will inevitably need it)

AbnerFederer commented 4 years ago

Hi,

Maybe you can remove the bt_app_hf.h file.

Thanks Abner

searock35 commented 4 years ago

Hi AbnerFederer, Thanks for responding. I removed that reference before I ran into this build error but mistakenly left it in the code. I changed the code on the GIST link to reflect that. My apologies, Corey

renzbagaporo commented 4 years ago

So does that mean this can be closed @searock35?

searock35 commented 4 years ago

Sorry, I should have made it more clear that the problem still persists. I am gonna try building it in the Eclipse build environment soon and maybe that will help?

renzbagaporo commented 4 years ago

Can you build the HFP examples? @searock35

renzbagaporo commented 4 years ago

Any updates @searock35 ?

searock35 commented 4 years ago

@renzbagaporo Sorry, I should've updated a while ago. I moved from my laptop to a different device and everything works fine there. I won't delve too deep into it now. Although I am closing this, I will answer your last question; I was able to build the examples, but my program I could not build. I might have forgotten to update the SDK config file when I did this, I'm not sure. Thanks for helping.
