multiple definition of g_pfnVectors[solved]

Posted by judoka_acl on 2017-07-19 10:20

This is the result of the linker when linking the startup_stm32f303xe.s assembly.

Invoking: MCU GCC Linker

arm-none-eabi-gcc -mcpu=cortex-m4 -mthumb -mfloat-abi=hard -mfpu=fpv4-sp-d16 -Wl,-Map=output.map -Wl,--gc-sections -o “emct_display_ac6.elf” @”objects.list” -lm

startup/startup_stm32f303xe.o:(.isr_vector+0x0): multiple definition of `g_pfnVectors’
MCT_OLED_Display/Libraries/CMSIS/device/startup_stm32f303xe_ac6.o:(.isr_vector+0x0): first defined here.


Interrestingly, I have another project with the same assembly and there are no errors there. Please provide some support, because the situation is very stacked. I can provide any further info or files.

Hi,
I got the problem,

you probably have twice the startup file in your env :

MCT_OLED_Display/Libraries/CMSIS/device/startup_stm32f303xe_ac6.s

startup/startup_stm32f303xe.s

If this is the case you should remove one from your env.
