Compiler options

[Joseph_R_]

Hi

I am getting the following error so my question is there an intel compiler option which would give better diagnostic i.e. say where size_t was originally defined

Thanks

C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\INCLUDE\crtdefs.h(494): error : invalid redeclaration of type name "size_t"

1> typedef unsigned __int64 size_t;

On Windows the compiler has a predefined value for size_t (__unsigned int on IA32 and __unsigned int64 on Intel 64).

What architecture are you using? What version of the compiler are you using (do an icl -V)?

Take a look at https://software.intel.com/en-us/forums/intel-c-compiler/topic/731328 ( Post #9 ) for an example of how it needs to be done. As already mentioned size_t is a reserved type and can't be redefined.
