Hi,
I have tried to compile and link the following file into tela. The
--shared version works if I remove the line with "cout <<". Do you
have any advise on what can be the problem? Tela uses dlopen() to
load the file.
TIA,
Micce
~/tmp$cat myfn.ct
// Our first C-tela example
[] = myfn(x)
/* myfn(x) checks that x is a positive scalar and outputs it.
Error codes:
1: x is not a positive scalar */
{
if (!x.IsScalar()) return 1;
switch (x.kind()) {
case Kint:
if (x.IntValue() <= 0) return 1;
break;
case Kreal:
if (x.RealValue() <= 0) return 1;
break;
case Kcomplex:
return 1;
default:
return 1;
}
cout << "myfn: x = " << x << '\n';
return 0;
}
