I want do this.

Code:

macro UINT chName { chName dd 0}

Code:

struc X
{
UINT x;
}

I want get size struc X, but fasm get me error.
I do mov eax,sizeof.X and get error.

I copy many struc from c++, and I want to do less work. Very Happy

You need to define what you want sizeof.X to be.

Code:

struc X arg {
  .:
  UINT arg
  sizeof.#arg = $ - .
}

This sample has a few things mixed. The "sizeof" defining line should look more like:

Code:

sizeof.#. = $ - .
