Just adding the prototype is likely to just postpone the problem till
link time (undefined symbol finite). I think that it would be better
to use the standard routine instead:

1) Find all references to finite and change them to isfinite.

2) For systems which provide finite() rather than isfinite(), add a
macro to <os>/epicsMath.h defining the latter as the former.

Hi,
On MacOSX 10.5, finite() is declared
extern int finite ( double );                   /* Legacy API: please
use C99 isfinite() instead. */
but not
extern "C" int finite(double);
This seems causing the error shown by Biritz-san.
1) replace call to finite with call to isfinite.
or
2) add
extern "C" int finite(double);
in somewhere in epicsCalcTest.cpp.
eliminates the error message.

Dear Tech-Talk,
so I am one of those Mac fanboys (at least when it comes to the
OS) who

installed OS X 10.5 (Leopard) as soon as it came out.
Naturally EPICS will not compile on it - would have been surprised
if it

had. I get the following error message:
../epicsCalcTest.cpp: In function 'double doCalc(const char*)':

../epicsCalcTest.cpp:31: error: 'finite' was not declared in this

Did I miss something in the installation instructions?
This is with base-3.14.9 on a PPC.
Thanks,
Bertrand

my environment:
Mac OSX10.5 running on MacBook(1st generation).
Xcode 3.0
EPICS R3.14.9 base
