#1 functions/spuc_math.cpp compile errors

[Gavin Voigt]

Below is a list of errors when compiling spuc_math.cpp
and fixed code. I have not determined the cause of the
last error. Compiled using Cygwin cygwin-1.1.7-1.

Could you detemine the cause the remaining error?

Regards
Gavin

-----------------
Code fix:
// function for hyperbolic cosine of x
double cosh(double x) { return((exp(x)+exp(-x))/2.); }

Same problem here, here is the message:
make
g++ -Wno-non-template-friend -c ../functions/spuc_math.cpp
-I../functions -I../generic -I../specializations
../functions/spuc_math.cpp: In function `double SPUC::cosh
(double)':
../functions/spuc_math.cpp:27: cannot convert
`SPUC::complex<double>'
to `double' in return

I did not try compiling with the version gcc 2.952. I am
currently using 2.96-99. Looking at the files in CVS (qpsk
directory) the latest update is about 4 months old and with
the problems I am seeing I wonder if the project is still alive?

You can fix this by prepending namespace std to exp().
i.e.
double cosh(double x) {
return ( (std::exp(x)+std::exp(-x) )/2. );
}
