Unable to use CMSIS library in Atollic TrueStudio

I am trying to use CFFT function for my STM32 microcontroller in Atollic TrueStudio. But I am unable to use any of the DSP functions. I get the error - undefined reference to `arm_cfft_f32' and undefined reference to 'arm_cfft_sR_f32_len16'. I don't know what the problem is because it works on Keil. What am I doing wrong?

#include 'stm32f4xx.h' #include 'arm_math.h' #include 'arm_const_structs.h' #include 'core_cm4.h' #include 'math.h' #define TEST_LENGTH_SAMPLES 32 float32_t ffttestip[TEST_LENGTH_SAMPLES]={0}; static float32_t ffttestop[TEST_LENGTH_SAMPLES/2]; /* Private macro */ /* Private variables */ /* Private function prototypes */ /* Private functions */ uint32_t fftSize = 16; uint8_t ifftFlag = 0; uint8_t doBitReverse = 1; int main(void) { int i = 0; i=15; i=pow(i,2); /** * IMPORTANT NOTE! * The symbol VECT_TAB_SRAM needs to be defined when building the project * if code has been located to RAM and interrupts are used. * Otherwise the interrupt table located in flash will be used. * See also the <system_*.c> file and how the SystemInit() function updates * SCB->VTOR register. * E.g. SCB->VTOR = 0x20000000; */ /* TODO - Add your application code here */ arm_cfft_f32(&arm_cfft_sR_f32_len16, ffttestip, ifftFlag, doBitReverse); /* Infinite loop */ while(1); }

EDIT - additionally,I get the following error -

no answer; but I got the same problem. Did you find a solution?
