Question

I am using g++ and I am compiling a linux c++ project. I get

src/fileC.cpp:181618: warning: cast from type 'const t__DeviceID*' to type 't__DeviceID*' casts away constness

Is there any -W option that suppresses that warning?

In normal cases we resolve that warnings, following the suggestion of the compiler, but for this file – which is not our code – we don’t want to modify it, at least for now.

Answer 1

While -Wno-cast-qual is probably what you want, you also might want to add in general the -fdiagnostics-show-option option to gcc, which will show you for almost all diagnostics which parameter caused it.
