SqPlus::Match' : none of the 43 overloads...
Author
I think I ran in a problem. I have couple of funtions taking
const pointers to parameters as:
..
DECLARE_INSTANCE_TYPE(Class1);
DECLARE_INSTANCE_TYPE(Class2);
..
class C
{
... void F(const Class1*, const Class2*);
};
SQClassDef<C>(true,"C").func(&C::F,"F");
compiles with:
error C2665: 'SqPlus::Match' : none of the 43 overloads could convert all the argument types
f:\getae\squirrel2_1_0_sqplus_15\sqplus\sqplus.h(632): could be 'bool SqPlus::Match(SqPlus::TypeWrapper<T>,HSQUIRRELVM,int)'
with
[
T=bool
]....
//all types.
if
..
void F(Class1*, Class2*);
..
compiles fine.

Thank you.
This seems to resolve half the problem. Now I have
this scenario
One param is const the other not.
And...
where 'dofile("filename.nut");' assumes the defaut directory?
If all scripts are in directory 'scripts/<>'
and the exe that loads the scripts are is un dir up
dofile("just file") does not finds the include file.
Therefore all dofile have to be nodified as:
dofile("scripts/<>") !!!. Is there a way to specify the
include paths for the engine.
Here are the compiler VC 2003 VC7 results.

re: file paths: I use paths relative to the current directory. You can write script functions and/or bind C++ functions to return strings to the current directory, absolute directory, etc., if needed:
dofile("Scripts/commonInit.nut");
// ScriptDir has been initialized to the full path to the script directory:
dofile(ScriptDir+"commonInit.nut");
re: additional issues: perhaps ask the question(s) on the Squirrel forum. If the problem has not been previously noted and solved, perhaps post the (general/complete) solution if you can find one.
dofile("Scripts/commonInit.nut");
// ScriptDir has been initialized to the full path to the script directory:
dofile(ScriptDir+"commonInit.nut");

I post at squirel forum home page
the workaround for sqplus to suport:
exporting Interfaces,
exporting Const and Volatile (of same type) paramaters in exported methods.
as:
class{
method(const Obj*, Obj*);
foo_set(const Obj*);
foo_get(Obj*);
}
.
Also I worked out include files paths for dofile("bla").
If interested please let me know. Is a functional fix
not quite 'academique'.
