List predefined macros

[eldiener]

In the Intel C++ Windows compiler is there a compiler command that will output the list of predefined macros to the console window ?

Hi,

There is a flag -dM -E which will give details of all macros. We generally use this flag and specify the empty file in Windows NUL.

You can also get the more detailed information regarding ISO Standard Predefined Macros and some Additional Macros from the below link:

All these resources will help you to find the Predefined Macros.

Warm Regards,

Abhishek

Your answer is not working for the Intel C++ Windows compiler.

Hi,

We also got the same error with ICL and ICX compiler and we have reported it to the concerned team.

Thank you for your finding. Meanwhile, you can go through the links that I have provided for getting more information regarding predefined macros.

We will get back to you soon.

Warm Regards,

Have you tried icl /E test.c?

I misunderstood that you wanted to see the macros of your program. You can icl /E /QdM  on a dummy testcase.

Let us know if this is still an issue. Otherwise, we will close it.

Thanks,
