[Wxlua-users] (int) should be int

[klaas.holwerda <kla...@nl...>]

Hi,

 From my bindings.i file i get generated things like:

extern (int) a2dDrawer2D_methodCount;

and

extern (int) s_wxluatag_a2dLauWrapper;

On fedora gcc 4.0.0-8 this does not compile, if i remove the () and make 
plain int all is oke.

Why is it (int), maybe it is better to generate it as only int?

regards,

Klaas

You need to add these lines to your rules file probably. Just use the
dummy macros i you don't want to export them.

-- Set the DLLIMPEXP macros for compiling these bindings into a DLL
--  Use "WXLUA_NO_DLLIMPEXP" and "WXLUA_NO_DLLIMPEXP_DATA" for no IMPEXP macros

output_cpp_impexpsymbol     = "WXDLLIMPEXP_WXBIND"
output_cpp_impexpdatasymbol = "WXDLLIMPEXP_DATA_WXBIND"

Hi John,

It seems to be only on Linux.

The two lines you mention are set to the next in my case:
output_cpp_impexpsymbol = ""
output_cpp_impexpdatasymbol = ""

But only on linux i get the (int) while on windows it is only int.

I find it hard to believe myself, but checking it again it looks like 
there is a difference here??
Do you have a switch somewhere in the binding generator?

Thanks,

Klaas

This can't happen, the genwxbind.lua doesn't do anything different in
msw or linux.

These should be set to these empty macros, see bindings/wx_rules.lua

output_cpp_impexpsymbol     = "WXLUA_NO_DLLIMPEXP"
output_cpp_impexpdatasymbol = "WXLUA_NO_DLLIMPEXP_DATA"

They're defined in wxLua/modules/wxlua/include/wxlbind.h

No difference between platforms and no switch.

Re: [Wxlua-users] (int) should be int

[Klaas H. <db...@nl...>]

Hi John,

Updating to the latest version of wxLua solved it. Actually it is the 
first time i get my app working with wxLua on Linux. (with the older 
version i had still static initialization problems).

So things go very well.

BUT when configuring wxLua, it did not find wxstedit correctly.
I did also install the lattest wxstedit. And lloked in /usr/local/lib/, 
and there is see libstedit.a and libsteditd.a which is gooed i think.
I did find stedit.h in /usr/local/include/wx/stedit/

So all fine i think.

Therefore i went to see in config.log, why configure did not find 
wxstedit. And there i see things like this:

This is the same problem I had with a `configure` based build with
mingw/msys on Windows.

The configure script seems to be using

#include <wx/stedit/stedit.h>

in a generated c file to see if the version of wxStEdit is OK. But
stedit.h needs to have some other headers included (wx.h?) to compile
properly.

I just tested my conjecture, and adding the line:

#include <wx/wx.h>

in the configure script here:

/* end confdefs.h.  */
#include <wx/wx.h>
#include <wx/stedit/stedit.h>

works for me.

Yes this has already been fixed in the CVS version of wxStEdit. I will
also adjust the configure script to #include "wx/wx.h" just to be
sure. Additionally I am trying to get configure to work a little more
seamlessly and have added some hacks so that you can specify the
wxstedit path and the actual lib to link against. Unfortunately we
need a nice way to systematically name the libs uniformly, ideally
using the exact same syntax for the build settings that wxWidgets
uses. (I have asked about that on wx-dev years ago, but the need for
this fell on deaf ears unfortunately) I think that we (I and other
wxCode people) should add this naming ability to our bakefiles, but
I'm not sure how to go about just yet.

I'm still trying to get the configure working properly. If you're
using Linux, you might want to just use the Makefiles in the src dirs,
where the ones in the apps dirs will automatically build whatever that
app needs. These Makefiles use wx-config and are fairly simple to
understand, they output the libs to the "wx-config --exec-prefix" dir
so that must be writable. The apps themselves are just compiled to the
src dir you're building from.

I will try to work some more on configure as I have not tried it
before a few days ago, unfortunately Francesco is away for the next
couple weeks and we use a modified version of Bakefile so some of the
changes they might need to be made can't be done properly until we get
the bakefiles redone.

Sorry about the problems, hopefully I can get it sorted out fairly quickly

I find the way the wxlua libs are named rather nice. And i thought the 
idea is to have it the way wxwidgets does it. Only wxlua in front of it.
We discussed this when the whole bakefile stuff started fro wxLua.
Why not use the same for stedit or any other wxCode project? Do you not 
like it?

I do like it, but it has to be implemented. The only problem is when
to find the time. :(

I see, same problem here with wxArt2D :-(
But knowing that  Francesco  is  very  far with a wxWindows package  
tool,  i think  it will eventually be organized that way.
At least i can not imagine packages working properly without a good 
naming convention for the generated libraries.

So maybe you should just wait a little in this case, until wxPm is out? 
I have the feeling this is what Francesco has in mind for wxCode ;-)

Klaas

Ok, we'll wait
