I have a stupid problem and I don't see where it comes from. I took care of using #ifndef directive to make sure all my #include are not redefined. Sadly for three of them that's happening. Here my multiple files arch :
t_include.h
#ifndef T_INCLUDE_H_
#define T_INCLUDE_H_
/* Project specific dependencies*/
#include "utilities.h"
#include "fsp_function.h"
#include "ti/csl/csl_tsc.h"
#include "ti/csl/csl_cache.h"
#include "ti/csl/csl_cacheAux.h"
#include "ti_sp_complex_convolution_A_input1.h"
#include "ti_sp_complex_convolution_A_input2.h"
#include "to_sp_complex_convolution_A_output.h"
#endif /* T_INCLUDE_H_ */
t_function.h
#ifndef T_FUNCTION_H_
#define T_FUNCTION_H_
#include "t_include.h"
/*output vector*/
#define INPUT1A_LENGTH 5000
#define INPUT2A_LENGTH 2800
#define OUTPUTA_LENGTH 2202
extern FLOAT32 sp_complex_convolution_A_output_thales[OUTPUTA_LENGTH];
/*misc parameter*/
#define CPU_CLOCK_KHZ 1400000
#define CPU_CLOCK_MS 1/CPU_CLOCK_KHZ
#define FIR_NB_MACS INPUT1A_LENGTH * OUTPUTA_LENGTH /* FIR algorithm complexity */
#define NB_OF_REP 10
#define UMA_L2CACHE_L1DCACHE 0
/* Project specific types */
typedef struct{
ect...
And now c file only include t_function.h :
t_function.c
/* Dependencies */
#include "t_function.h"
FLOAT32 sp_complex_convolution_A_output_thales[OUTPUTA_LENGTH];
/* API */
etc...
And t_main_function.c
/* dependencies */
#include "t_function.h"
void main(void) {
etc...
It should work but during linking here the errors comming :
<Linking>
error #10056: symbol "sp_complex_convolution_A_output" redefined: first defined in "./TEST/t_function.obj"; redefined in "./TEST/t_main_function.obj"
error #10056: symbol "sp_complex_convolution_A_input2" redefined: first defined in "./TEST/t_function.obj"; redefined in "./TEST/t_main_function.obj"
error #10056: symbol "sp_complex_convolution_A_input1" redefined: first defined in "./TEST/t_function.obj"; redefined in "./TEST/t_main_function.obj"
error #10056: symbol "sp_complex_convolution_A_output_thales" redefined: first defined in "./TEST/t_function.obj"; redefined in "./TEST/t_main_function.obj"
>> Compilation failure
error #10010: errors encountered during linking; "CONVOLUTION_COMPLEX.out" not built
So the error only com from three symbol sp_complex_convolution_A_output, sp_complex_convolution_A_input1 and sp_complex_convolution_A_input2 Which are defined in their own .h which is also protected by #ifndef directives:
ti_sp_complex_convolution_A_input1.h
#ifndef __TI_SP_COMPLEX_CONVOLUTION_A_INPUT1_H_
#define __TI_SP_COMPLEX_CONVOLUTION_A_INPUT1_H_
FLOAT32 sp_complex_convolution_A_input1[2 * 2500] = {
etc...
And the same for the other two...
So I really don't know why it is happening. Thx for helping
Definitions like:
FLOAT32 sp_complex_convolution_A_output_thales[OUTPUTA_LENGTH];
should go into a source file.
The header files should contain only declarations like:
extern FLOAT32 sp_complex_convolution_A_output_thales[OUTPUTA_LENGTH];
As a rule of thumb, do no put anything that allocates memory into header files.
