Native types can't be used with pointers.

Why is this a fatal error rather than a compiler warning as in case of function CreateGadgetList()?
Why presence of type at the pointer does not allow the code to compile? Prior to version 5.10, it was not a problem, and now a fatal error, with a stop compilation! Why?

This has already been discussed repeatedly here on the forum.

But still not fixed.
It is not an error which requires stopping compilation. This should be a warning.

There is nothing to "fix" in this respect.
You can read more detailed information in the previous discussions here (that's why I mentioned them).

One of the many threads about it, here you can read different opinions on the subject and the reasons behind the change

For someone who talks about how smart they are, you've never heard of "search"?

But the compiler can such string
convert to
And then all will be well.
Why, instead this is error?

In the second post of topic, Fred did not answer.
I have the same situation as the author, the topic on
your link.
Code: Select all
Macro LongLong : q : EndMacro
x.LongLong
*y.LongLong

You couldn't access the quad value on the pointer in a structured way (*y\q doesn't work with native types),
so you have to use another way.
Code: Select all
Macro LongLong : q : EndMacro
Macro LongLongPtr : Quad : EndMacro
x.LongLong = 12345
*y.LongLongPtr = @x
Debug *y\q
*y = @x
Debug PeekQ(*y)
*y_LongLong = @x
Debug PeekQ(*y_LongLong)

The use of different types (macro), for variable and pointer, it is "dirty" code!
Above cited the example of automatic type conversion from l to Long.

It is your choice. You can use:
- *x (without any type)
- *x.LongLongPtr
- incorporate the type in the name: *x_LongLong
Use what you want, all 3 options work.

I suggested this, too, back when the change was made. As you can see, it got not changed to this way, as they didn't like it.
You are really late. It has all been discussed extensively, and nothing got changed.
They will not change it now, just because User_Russian wants the change. Get used to it.

This is unacceptable for a paid product! We bought a PB and I think we have the right not to influence its development.
But the development is entirely dependent on the position of Fred and the team. The majority opinion does not mean anything!

Yes, that's absolutely correct.

I don't see why this is still a discussion topic. I think it is only logical that this isn't permitted
by the compiler any more. Also, a structure as 'type' for the pointer is logical, because it allows
for accessing the structure fields in that specific block of memory.
I never thought native types on pointers were logical in PureBasic, I mean, it's not like you could
do stuff like this:
Code: Select all
float *buffer = (float *)malloc(20);
*(buffer + 10) = 11.52;
In PureBasic. Structured 'types' were always required to do so (.Float)
Code: Select all
*test.Float = AllocateMemory(20)
*test + 10
*test\f = 11.52
Anyhow, we all know this is probably not going to change, so why not move on right?
