1. I tried today SQLCommander. I wonted to connect to MySQL but when I compiled it and started there wasn't MySQL support. Looked the code and find next

#ifndef flagNOMYSQL
    #define HAVE_MYSQL
  #endif

but I wasn't define anywhere flagNOMYSQL nor anywhere in the code I found a place where that flag is defined. How to compile SQLCommander with MySQL support?

2. Also doing digging in uppsrc (amassing what already exist there:) and find intersting package Geom with some subpackages. But I can't figure it out what exactly it is for (there are 2D and 3D vector support, and lots of stuff) so could anyone give some explanation. Also I am very interesting in 2D and 3D vector geometry - is U++ have already some ctrl for this (besaide OpenGL ctrl)?

3. Started to write topic for refence\CalbackArgTarget and next line is not completely clear to me

CallbackArgTarget<int> result;

Now for this to work type has to be Null able. Thats probably mean that int is actually not a C++ keyword or maybe it is??; is it some kind of class? Searched uppsrc and found next

NTL_MOVEABLE(int)

hmmm, don't know what this is exactly - are now int wrapped in some kind of Movable and Null type?

4. I think that I found little error in Topic::src::Callbacks::CallbackArgTarget::IsNullInstance(). It says

Return value...True if there is not Null in output value.

maybe it should says without 'not'

Return value...True if there is Null in output value.

That's it for now.
