Why do GCC and clang show "error: initializer element is not constant" and "error: initializer element is not a compile-time constant" (respectively) when defining a function-scoped static pointer initialized to an unnamed array; but, when defining the same static pointer to the same unnamed array in file-scope they manage just fine.
I have compiled the same program using a compiler for embedded H/W, which compiles without error.
Here is a code snippet with the error active:
int foo()
{
static int *ptr = (int[]) { 9, 8, 7 }; /* COMPILE ERROR */
return ptr[2];
}
int main(void)
{
return foo();
}
And here is a similar code snippet with the static pointer in file scope, which GCC and clang compile without issue:
static int *ptr = (int[]) { 9, 8, 7 }; /* File-scope is fine */
int foo()
{
return ptr[2];
}
int main(void)
{
return foo();
}
I can of course define a separate static array inside my function and point my static pointer to that array, but I want to use an unnamed array. I have tried different compiler flags to no avail:
-std=c90-std=c99-std=c11-std=gnu11
