Both Development Studio and DS5 fail to load debug symbols off gcc-generated ELF

Sri over 4 years ago

Hi,

This is is what I've discovered, and I am hoping it helps others:

When we upped the C++ std support from 11 to 17 with the GCC option -std=gnu++17, both DS5 (all versions) and Development Studio (v2021.0) failed while loading symbols from our ELF.

We're using a Xilinx-supplied gcc cross compiler (for Cortex A9), version:

make-C:\dev\akd\trunk1\make>arm-none-eabi-g++ --version
arm-none-eabi-g++ (Linaro GCC 7.3-2018.04-rc3) 7.3.1 20180314

The fix is to add the following options to the g++ compiler: -g -gstrict-dwarf -gdwarf-3

Don't forget to do a clean make.

Best,
Sri

Hi Sri Thanks for sharing :) The Debuggers of DS-5 and Arm Development Studio supports standard DWARF debug information up to DWARF4. Maybe the compiler was originally generating something in its...

Hi Stephen,

Thanks, I did verify that GCC+DS-5 works with gdwarf-4.

We're due for an upgrade of our tools, so I will try with a later version of GCC to see if it works without adding the "strict" behavior.

Best,
