Errors about g++_CilkPlus

Hi, everyone, I installed CilkPlus gcc on my fedora as the following http://cilkplus.org/build-gcc-cilkplus, after I installed it

I compile BlackScholes-ArrayNotations.cpp BlackScholes-CilkPlus.cpp BlackScholes-Main.cpp BlackScholes-Serial.cpp using commands

"/home/kain/Software/cilk/gcc-cilk/bin/g++ -ldl -fcilkplus -lcilkrts BlackScholes-ArrayNotations.cpp BlackScholes-CilkPlus.cpp BlackScholes-Main.cpp BlackScholes-Serial.cpp -o cilk"

But some compile errors happened

BlackScholes-ArrayNotations.cpp:25:13: error: expected constructor, destructor, or type conversion before ‘(’ token
__declspec(vector) static double N(const double& z) {

below is the definition of this function

25 __declspec(vector) static double N(const double& z) {
26
27 if(z > 6.0) { return 1.0; }; //guards against overflow
28 if(z < -6.0) { return 0.0; };
29 double b1 = 0.31938153;
30 double b2 = -0.356563782;
31 double b3 = 1.781477937;
32 double b4 = -1.821255978;
33 double b5 = 1.330274429;
34 double p = 0.2316419;
35 double c2 = 0.3989423;
36 double a = fabs(z);
37 double t = 1.0/(1.0 + a*p);
38 double b = c2*exp((-z)*(z/2.0));
39 double n = ((((b5*t+b4)*t+b3)*t+b2)*t+b1)*t;
40 n = 1.0 - b*n;
41 if(z < 0.0 )
42 n = 1.0 - n;
43 return n;
44 }

I guess "__declspec(vector)" could only be identified by Visual Studio , but how can I use it in Linux?

Thank you for your help!!

Hello Xia,

Please try using __attribute__ ((vector))

Thanks,

I got it, in gcc, you need not to specify vecotr, and use it as normal, a[:] = Function_array(), it can be compied in my environment
