I am a newbie in stm32 programming and I am using stm32 in Linux. I could build my first project without any error. but when I added some new parts into my code which requires one new source file and header file (which I also added). The IDE started giving these two errors:

recipe for target ‘STM32L4xx-SensorTile.elf’ failed makefile /STM32L4xx-SensorTile/Release line 45 C/C++ Problem
make: *** STM32L4xx-SensorTile.elf Error 1 STM32L4xx-SensorTile C/C++ Problem

And this is the console output from the build:

09:43:02 **** Incremental Build of configuration Release for project STM32L4xx-SensorTile ****
make all
Building target: STM32L4xx-SensorTile.elf
Invoking: MCU GCC Linker

collect2: error: ld returned 1 exit status
makefile:45: recipe for target ‘STM32L4xx-SensorTile.elf’ failed
make: *** STM32L4xx-SensorTile.elf Error 1

I checked online, saw some linker-related solution suggestions but could not make them work. Can someone help me with this, taking into account that I am a newbie so I need simple explanations?
