dsho,
For MathLib...
Make sure you include this code (or appropriate variant) in your Application
Startup Function:
Err error;
// link in MathLib
error = SysLibFind(MathLibName, &MathLibRef);
if (error)
error = SysLibLoad(LibType, MathLibCreator, &MathLibRef);
ErrFatalDisplayIf(error, "Can't find MathLib");
// Just an example; handle it gracefully
error = MathLibOpen(MathLibRef, MathLibVersion);
ErrFatalDisplayIf(error, "Can't open MathLib");
Make sure you include this code (or appropriate variant) in your Application
Shutdown Function:
UInt usecount;
Err error;
error = MathLibClose(MathLibRef, &usecount);
ErrFatalDisplayIf(error, "Can't close MathLib");
if (usecount == 0)
SysLibRemove(MathLibRef);
Also, make sure you include "MathLib.c" in your project files, and
"MathLib.h" in the source files that are going to use MathLib. Since I had
the old "typedefs" in my code, I also include <PalmCompatibility.h> so that
"UInt usecount;" compiles.
If you're using PalmOS 3.5 SDK, make sure you modify MathLib.c and change
the line:
#include <Pilot.h>
to
#include <PalmOS.h>
#include <PalmCompatibility.h>
In the project settings obtained by ALT-F7, Under Code Generation, 68K
processor, make sure Floating Point is set to PalmOS.
I hope this helps with your MathLib issues, as this works fine for me.
