what's your ide? Arduino or PlatformIO? Please provide more detail

Arduino IDE 1.8.16 Compile for STM32F103C

[zackees]

From looking at the stack trace here my guess is that one of the types in the inline function port_ptr_t port(); has been forward declared but not defined.

The likely culprits are that port_ptr_t type, or the type of _GPIO. My advice would be to find the headers that have these class definitions and include them BEFORE you #include <FastLED.h>, that way you'll force the compiler to see the full type definition of the problematic class/struct and it should fix it. If this fixes it, please let us know what header needed to be included.

Same issue on platformio

[env:bluepill_f103c8]
platform = ststm32
board = bluepill_f103c8
framework = arduino
board_build.core = maple
board_build.ldscript = jtag_c8.ld

works with this fix https://github.com/FastLED/FastLED/issues/883#issuecomment-549295179
