Hello,
I try to use the DSP libraries (FFT) in a project, but I have the error :
In function `pow':
pow.c:(.text.pow+0x46a): undefined reference to `errno'

When I use the project given as example, I don't have this error, and I think I have the same parameters in both projects.

Any suggestion ? Thank you.

Use of errno currently requires you to be linking with the nohost or semihost variant of the C library. For more information, start of by looking at the FAQ:
