Hi,
On a Get Start thread of this web site, it has a short NE10 example having such snippet:
I install NE10 library. In the documentation, it has a different definition:
ne10_result_t ne10_addc_float_neon (ne10_float32_t *dst, ne10_float32_t *src, const ne10_float32_t cst, ne10_uint32_t count) asm("ne10_addc_float_neon")
I am curious about the last "asm("ne10_addc_float_neon")". Could you tell me that?
Thanks,
Excuse me for the previous question. I find that it is caused by the generated documentation, which is wrong after I check the on-line documentation.
Now, I have a new question when I build another simple example from the right NE10 documentation:
int main()
{
ne10_result_t status;
printf ("Going to initialize NE10...\n");
status = ne10_init();
if (status != NE10_OK)
printf ("NE10 init failed.\n");
printf ("NE10 has been initialized.\n");
test_add1();
test_add2();
return 0;
}
I find that "
will cause build errors, such as:

I have no idea on how to solve this. Please help me!

you should add -lm when you compile your code
