How to properly convert c ++ project?
Most of the displayed error are due to misinterpretation by Eclipse CDT. You can remove then by rebuilding the index (Right click on the project, Index > Rebuild)
On console view, it says that the Error_Handler() does not exists. By default CubeMX should generate it in main.c, maybe something wrong happens in the generation process.
Here the default function :
/**
* @brief This function is executed in case of error occurrence.
* @param None
* @retval None
*/
void Error_Handler(void) {
/* USER CODE BEGIN Error_Handler */
/* User can add his own implementation to report the HAL error return state */
while(1)
{
}
/* USER CODE END Error_Handler */
}
