Compiler's weird type check for pointers: bug or intended?

[dlOuOlb]

The compiler does not allow to assign from a variable pointer to a constant pointer, like following:

Code Select Expand


int main(void)
{
    char *Foo="Hello.";
    const char *Bar;
    const char **Baz;

    Bar=Foo;
    Baz=&Bar;   //no warning, no error

    Baz=&Foo;   //error #2168

    return 0;
}

error #2168: Operands of '=' have incompatible types 'const char * *' and 'char * *'.

I know that Pelles C is strict at type check, but is it intended even for this case?

cast it

Code Select Expand

...
Baz=(const char**)&Foo;
...
clang:

Code Select Expand

warning: assigning to 'const char **' from 'char **' discards qualifiers in nested pointer types [-Wincompatible-pointer-types-discards-qualifiers]

I searched the clang's warning message in your answer, and found this answer:

So it is not a compiler-specific issue, but the language's one.

Thanks.
