[wxCode-users] Can't compile my own component in Linux. Works fine with VS C++ 2005

[<msz...@ya...>]

Hi wxCoders!
I hope you can help me. This might be a more c++ related question but I fee=
l=20
that you are the only ones that can help me. HELP!!! :(

I'm tryng to comile my component (wxActiveRecordGenerator: activerecord mod=
ule=20
in wxCode CVS).

I'm in Kubuntu using wx2.8 and gcc 4.1 and DatabaseLayer 1.6. I'm having=20
linking errors when doing a "make -f GNUmakefile".

Hope you can help...

Regards Mat=EDas.

This is the output:

btw: referencia a `vtable for xxxx' sin definir =3D undefined reference to=
=20
`vtable for xxxx'
All the methods are defined  so I really don'tget the error messages...and =
I=20
have no virtual functions. I should be getting linker errors against=20
DatabaseLayer because I haven't compiled it yet.

For starters you may want to try adding virtual destructors for these
classes, just an empty one like this. I think I've seen error messages
like these before and I'm guessing that they are from the base class
having a vtable, but your subclassed class doesn't explicitly have
one.

in DatabaseConnectionDlg.h add
virtual ~DatabaseConnectionDlg() {}

Hope this helps,

	I did this John. But I made it a non-inline virtual destructor. Because I'=
ve=20
read that the vtable shall be alocated in the first non-inline virtual=20
function.
	Anyway now I'm getting undefined reference to vtable for the destructors. =
:(
=2E.. plus the previous errors.

	I do think you are pointing the right way here, but I don't know what to=20
do...

Thanks,=20

Another reason might be mixing up Debug wxWidgest with non debug applicat=
ion code.
( flags like __WXDEBUG__ and such )

Hi Klaas,

I'm not using such flags in my code.=20
And I'm using the bakefile generated GNUmakefile.

Re: [wxCode-users] Can't compile my own component in Linux. Works fine with VS C++ 2005

[Francesco M. <f18...@ya...>]

yet another source of problems maybe the library order: since it compiles with 
MSVC (where lib order doesn't care) but doesn't under Linux I suggest you to 
check that all libraries are orderered in this way:  A B C where A is the lib 
which depends on B and C, B is the one which depends from C and so on (i.e. a 
library X may only depend from libs listed _after_ X).

Another suggestion is to change (from console and temporarily) your locale to be 
"en_us" (american english) and then copy&paste your error message to google 
removing the name of your specific function :D

HTH,
Francesco

Hi Francesco,

this is what I have in  my bakefile currently:
	 <wx-lib>xml</wx-lib>
        <wx-lib>core</wx-lib>
        <wx-lib>base</wx-lib> <!-- base must be last wx-lib -->

I've already did. Not much information except the one about the vtable bein=
g=20
put at the first non-inline virtual function.

But, I use NO virtual functions in this table.

Thanks,

Hi Matias,

Now i have the same for wxArt2D, never seen it before, but after=20
updating  to fedora6, its there.
If i find it i let you know :-)

Damn, tough luck!

Did you changed of gcc version? I'm using 4.1 and that's when the problem=20
started. And I've updated to wx2.8 but  i don't think that is it.

Good luck with that, Mat=EDas

    Well, I finally got it working. But I don't know what it was. I just
used brute force: regenerated the GUI skeleton and copying the code from
the old source piece by piece and compiling every change. Nothing
happened, it all went smoothly and there weren't any undefined methods
at the end...so...no idea why it didn't worked before. All I can guess
is that it had something to do with the order of declaration/definition
of the methods.

Sorry for not finding the problem/solution.
Regards, Matías

And in my case it were really missing implementations of declared virtual members in the base class.
This is because of a newer gcc, since the code compiled already a long time on Unix.
