try declaring your routine as a static function.
static void HelloLibSquare...
There is nothing wrong with using floats or doubles in libraries..

Subject: floats in syslib shared library under prc-tools 2.2?
> I'm trying to build a simple "Hello Lib" example syslib library using
prc-tools 2.2. Other than the open, close, sleep, and wake functions, the
only function in the library looks like this:

> void HelloLibSquare( UInt16 refnum, float in, float* out ) {
> *out = in * in;
> return;

view the hellolib file and it shows nonzero-sized .data and .bss segments.
Curiously, if I comment out the first line of the body of HelloLibSquare,
the warning goes away and the .data and .bss segment sizes are zero. The
same is true if I make my arguments ints instead of floats.

(or double--that bombs, too) for my arguments?
