Hi all.
Have to start write something under psp and confuzed with such linker error:
undefined reference to `sinf'
so, i'm compile well few examples which used sinf and cosf. Try to understand my mistake but cant find it :( i'm use same includes and makefile but nothing ... so may be i miss something - can anyone can help with such, i guess, lame propblem ;)
p.s. so don't use C a long time (last 5-6 year write only on asm for MCU) and forget it completely... so trying to relearn it anew. |

sinf does exist (along a lot of other math functions), but you need to link with the math library. add -lm when you link (you must add it before the objectfile or code that uses it).
If you can't make it work, then post your makefile, and I'll take a look.
