i have the following code that yields an compile-time error (using OpenCL compiler, AMD APP 1445.5 on Intel Core i7, using static C++ extensions):
namespace myNS
{
using ::fmin;
}
void test()
{
float f = myNS::fmin(1.0f, 2.0f);
}
results in
Error: "fmin" has already been declared in the current scope
Error: "fmin" has already been declared in the current scope
Error: "fmin" has already been declared in the current scope
Error: "fmin" has already been declared in the current scope

"OpenCL-CPP-JIT-Source", line 9: error: a value of type "double16" cannot be
used to initialize an entity of type "float"
float f = myNS::fmin(1.0f, 2.0f);
i can get rid of the error if i insert the following declaration at the begin of the code snippet:
float fmin(float, float);
This is not specific to fmin, but i assume for all built-in, overloaded (?) functions (i've only tested a few: fabs, min, max...)
Why do i have to declare the built-in function in this case first?
Have i missed something or is this a compiler problem ?
thanks and regards,
