IDF Compiler settings are TERRIBLE for JTAG debugging

[jhinkle]

Why offer JTAG debugging when the IDF setting make using JTAG useless.

If you set compiler for Debug - most all the variables are optimized out.

If you set it for no-optimization - the variables are unavailable because no debugging info available.

There is NOT a compiler setting that works.

I've tried various methods to modify the compiler flags (just for my files) and nothing works.

What is needed is -g -O0 combination for debug with no optimization.

Please tell me how to compile just my files - with those flags.

Thanks.

Thanks for the reply.

THAT was one of the many I tried. I have compiler set for no optimization in the sdk config and added add_compile_options(-g) as the last line in my CMakeLists.txt in main.

No change in behavior.

Did I use the add_compile_options() improperly?

Thanks

You can check the exact compiler commands generated from your CMakeLists.txt in build/compile_commands.json.

I tried adding add_compile_options() to the CMakeLists.txt in Main but the build process fails stating that the command in not-scriptable.

Added it to the CMakeLists.txt in the project folder -- see below

Code: Select all

# For more information about build system see
# https://docs.espressif.com/projects/esp-idf/en/latest/api-guides/build-system.html
# The following five lines of boilerplate have to be in your project's
# CMakeLists in this exact order for cmake to work correctly
cmake_minimum_required(VERSION 3.5)
add_compile_options( -O0  -g )
include($ENV{IDF_PATH}/tools/cmake/project.cmake)
project(FD_Remote)

Every things compiles and links. Run the JTAG debugger and all variables are identified as "unavailable".

Here is a entry from compile_commands.json

You can see where the add_compile_options() were used -- look 9 lines from bottom and about 10 chars in.

Any thoughts as why still no debugging information available?

Dunno. Maybe "-g" doesn't do anything with the xtensa-esp32-gcc and "-Og" is the best you'll get.
