Using the arm DSP library

[vard]

Hi,

I’m currently evaluating VGDB in VS13 and in one of my files, I’m calling a function covered by the arm_math.h file.

The code: val = arm_sin_f32(…. etc.
is causing the error message:

Error 10 error VGDB1000: undefined reference to `arm_sin_f32′

The arm_math.h file is included, and inside the file the function’s prototype is declared as

float32_t arm_sin_f32(
float32_t x);

but it looks like the actual function declaration is not part of any library I can find. Any ideas on how to get the DSP math functions as defined in the arm_math.h file to work VGDB?

Thanks!

It works now, now worries, I had a space in the name path to the arm_math library and the make did not like that. I moved the arm_sin_f32.c together with my source files and it compiles fine.
Thanks!

Hi,

Thanks for reporting back, good to know it works now. Yes, you should avoid using paths with spaces in them when using gnu tools. Even if make would accept a path with spaces in it, then gdb could still produce strange errors etc.
