Hello there,

I just tried to use the sin() function of the math libraries (#include
<math.h>) but it doesn’t seem to compile properly. some other functions from
the same library are not accessible either.

I tried to compile the program with “qcc” first. When compiling it with
“QCC” (capital letters) it works fine and I get the right results. Is there
maybe no “sin()” function for the normal c-library available but just for
C++? Where can I get the library for C?

Thanks.

Did you try -lm? It will link with libm…

Try linking in the math libs:

qcc -lm -o [program] something.c
