Currently, there is not a comprehensive document that lists the diagnostic (such as error, warning or remark) definitions for the Intel® C++ Compiler for Windows, Linux* and Mac OS*, and Intel® Parallel Composer. But we've started to document all the Intel C++ Compiler diagnostic messages in our Knowledge Base. If you need to find more information about a specific diagnostic, let us know at the Intel® C++ Compiler User Forum or the Intel® Parallel Studio User Forum. This will help us prioritize diagnostic descriptions for updating.
Intel® C++ Compiler for Linux* and Mac OS* Diagnoses More Warnings than GNU Compilers
Typically the Intel® C++ Compiler emits more warnings than the GNU Compilers. These warnings alert programmers to potentially non-portable or dangerous situations.
To disable warnings or errors
If the diagnostic has a number associated with the message (for example, 111), you can disable the message:
prompt> icpc -wd111 a.cpp
You can disable multiple warnings by using a comma-separated list.
prompt> icpc -wd111,222,333 a.cpp
Intel® C++ Compiler for Windows* 10.1 or 11.0 Diagnoses More Warnings than Visual C++* Compiler
In most cases the Intel C++ Compiler for Windows emits more warnings than Visual C++ compiler. You can disable the warnings or errors with following command:
prompt> icl /Qwd111 a.cpp
Intel® Parallel Composer beta Behaves the same as Visual C++* Compiler in emitting diagnostics
By default the Intel Parallel Composer beta behaves the same as Visual C++ compiler in emitting diagnostics. If you'd like to see more warnings or errors, please add following option to the project property "C/C++ -> Command Line -> Additional Options" field.
