Linking script is broken when using -g3 debug flag
What kind of issue is this?
- [X] PlatformIO Core. If you’ve found a bug, please provide an information below.
Configuration
Windows 10
PlatformIO Core, version 5.2.5
Custom blackpill_f411ce mbed 6 target
Description of problem
Compiling a debug build with debug_build flags including "-g3" causes the resulting .pio/build/blackpill_f411ce/stm32f411xe.ld.link_script.ld to have extraneous lines in it which break the link step. These extra lines appear to be unwanted MACRO expansions that are mentioned in the man file as a difference between -g2 and -g3 flags.
Steps to Reproduce
- change the platformio.ini to debug and add -g3 to debug_build_flags
- attempt to build the project
- wait for
collect2.exe: error: ld returned 1 exit status
Actual Results
Linking fails because of a syntax error in the .pio/build/blackpill_f411ce/stm32f411xe.ld.link_script.ld file.

Additional info
I was trying to resolve a related issue as to why debug builds were not including debug symbols in the resulting .elf file. In the process of playing with different debugging flags I uncovered this issue. I am not sure if some unwanted macros are being expanded in the linker_script.ld file because of the -g3, or if that is a red herring. I still have to make an issue for the missing debug symbols.
A difference that I see between the Env of a build with debug_build_flags = -g3 and a default debug build is that LINKFLAGS contains -g3 and other debug_build_flags if specified in the platform.ini. Maybe we should strip those out like the -Wl,-T flags are stripped out in platforms/ststm32/builder/main.py?
LINKFLAGS from Env with debug_build_flags = -Og -g3 -gdb:
'LINKFLAGS': [ '-T',

On a side note, where do the LINKFLAGS come from for an mbed 6 build?
This problem also effects Nordic NRF52-DK
I have discovered a problem with my platformio.ini. I was not using the src_filter correctly, which caused the original build issues and missing symbols (because there was no main.o included) that led me to playing with the debug_build_flags.
However after fixing the platformio.ini I can still reliably reproduce the issue in the linking stage and the LINKFLAGS Env variable by adding a debug_build_flags = -g3 to platformio.ini.
