### More Information.

FYI I paired down some of the non-essential information
Sherry616 commented 1 year ago

Hi @parksj10, "ld returned 1 exit status" indicates a compilation error. It seems that the code has not been successfully compiled yet. Typically, our development process, including the release and GitHub versions, ensures that the code is thoroughly tested and compiles without any issues. However, considering the recent change in the CMakeLists.txt file, it might be necessary for you to investigate the root cause on your own first.

igrr commented 1 year ago

The issue likely occurs because your main file is a C++ source file, while the implementation of these functions is done in C source files. In this case, you have to inform the C++ compiler that the functions are declared with C linkage. Please try adding #ifdef __cplusplus/extern "C" {/#endif guards in your header file. Otherwise the C++ compiler will consider that the functions register_system and others are declared with C++ linkage.

For more information about combining C and C++ code, please see the docs: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/cplusplus.html#combining-c-and-c-code.

parksj10 commented 1 year ago

@igrr out of curiosity, it's clear you have a ton of experience/expertise with this stuff, but how would someone such as myself know/figure out that this lack of C++ guard was causing the issue (I.e. from the ld error I was getting)?

igrr commented 1 year ago

It's not a guaranteed way (there's always a chance of some odd bug haha!) but trying to follow the linker logic helps fairly often. Ask yourself questions like, "should the linker be able to find the library?", "is the function actually in the library?", "is the name of the function defined in the library same as the function being referenced?" and so on:

  1. Determine the library ("component" in IDF) where the caller is. In this case, this is main (a.k.a. hw/main/)
  2. Determine the library where the "missing" functions are supposed to be located. In this case, that is blemesh_console.
  3. Is there a dependency between the two at CMake level? In this case — yes, there is: blemesh_console is in the requires list in hw/main/CMakeLists.txt. Also, most of the time if the dependency at CMake level is missing, you will get a compile time error that the header file is not found.
  4. If there is a dependency at CMake level, then the library linking order is correct. What else can be wrong? At this point I would find the static library where the missing functions are supposed to be (libblemesh_console.a), and use objdump (xtensa-esp32-elf-objdump) to check whether the functions are actually there.
    • this might show that the whole object file is missing, if for instance you forgot to compile the .c file where the functions are
    • or the object file is there, but functions which are supposed to be inside are not there — could be because they were surrounded by some #ifdef which got preprocessed out
    • or the functions are there, but the names are mangled — something like _Z15register_systemv instead of register_system — this is the case you had
    • or the function is there, but there is a typo in the name of the function defined, compared to the function declared
    • possibly some other options, can't think of anything right now.

Hope this helps!

parksj10 commented 1 year ago

That's super helpful! Thanks so much for all the details and help! I had no idea about the objdump that's definitely gonna come in handy. I actually checked the build folder and saw the _Z15Register_... thing but I didn't realize it wasn't supposed to be like that

clovisf commented 3 months ago

I was having the same issue, using Arduino IDE 2.3.2 and trying to compile an example with the BluetoothSerial library from here: https://github.com/espressif/arduino-esp32/tree/master/libraries/BluetoothSerial , for the DFRobot Beetle ESP32-C3 and also SeeedStudio Xiao ESP32-C6.

I added `#ifdef __cplusplus extern "C" {

endif`

to the main code (seen below) and now am getting the `exit status 1

Compilation error: conflicting declaration of 'void setup()' with 'C' linkage` error. Any help? Complete code I am trying to compile on Arduino IDE:

`#include "BluetoothSerial.h"

ifdef __cplusplus

extern "C" {

endif

BluetoothSerial SerialBT; String MAC_Address;

void setup() { Serial.begin(115200); SerialBT.begin("ESP32 Bluetooth"); }

void loop() { MAC_Address = SerialBT.getBtAddressString(); Serial.println(MAC_Address.c_str()); delay(500); }`
