1. Question about wxEuphoria

Hello,

I started to work with wxEuphoria 12.1 and Euphoria (rev 1371) a little bit in Windows (Vista). Some examples work, some do not.

First thing I did was to replace all global with public in wxeud.e in order to ensure not to run with Eu 3.1.1. Also ensured only to use std/include files.

I also added in about line 1597 get_ptr:
...
WX_XY_TO_POSITION = wx_define_c_func( "xy_to_position", {C_INT,C_INT,C_INT}, E_OBJECT ),@define
get_ptr = wx_define_c_func( "get_obj_pointer", {E_OBJECT}, E_OBJECT ),

and commented out about line 3786:
...
constant get_ptr = define_c_func( wxWidgets, "get_obj_pointer", {E_OBJECT}, E_OBJECT)
...

As you introduced wxDEBUG this is a good means to see what functions are not linked correctly. These are my results:

Failed to link function: +find_window
Failed to link function: +get_linkinfo
Failed to link function: +get_staticbitmap
Failed to link procedure: +set_mdi_child_title
Failed to link procedure: +set_staticbitmap
Failed to link function: +get_obj_pointer
Failed to link variable: null_pen
Failed to link variable: null_brush

It seems something is missing in the provided dlls for wxEuphoria. Can I compile them myself using Watcom and what must I pay attention to?

I can see that at wxwidgets.org Release 2.8.9 is offered for download. Can I use the provided files in wxEuphoria/src for this release too?

Thanks in advance for any help
Roland

Hi Matt,

thank you for your hints. I tried wxwidgets 2.8.7 and following the readme.txt in wxEuphoria/src I could build wxmsw28u_wat_eu.dll. But unfortunately I cannot build libwxeu.dll. These are the last lines in my console window:

...

This is a little bit too much to read through for me in the moment.
I only can find get_linkinfo in src/wx.h and get_obj_pointer not at all. Is there a missing cpp file in wxEuphoria/src of version 12.1?

I included the binaries in the version 12 and 12.1 releases. Could you use those for the time being, until we sort this out?

There will be machine level exceptions. The library is stable, a handful of things simply don't work. If you run all_demos.exw, it should give you a description of the demos, some of which say "broken."

And how'd this thread get broken...?

Today I had some time to run the demos of wxEuphoria with Eu 4.0 rev 1378. I used wxeud.e of wxIDE. Some errors of the demos were caused by some missing files which I found in the demo folder of version 12.0 of wxEuphoria and in win32lib: tbar_xpm.e, xpm_icon.e and xrc_demo.xrc. In list.exw I think there is a logic error in procedure Click_Button1: index should be of type object and the line:

if index = -1 then
should be changed to:
if equal(index, {}) then.

Apart from these minor exception the demos of wxEuphoria run very fine on my machine. And so does wxIDE which shows a lot of potential.

Nevertheless it would be nice if libwxeu.dll could be updated. The cause for the few link failures can be solved by updating exports.lbc like Matt noticed. The demos are not affected, but wxIDE is. (set_pen and set_brush in wxIDE_Syntax.ew will not work.)

Dan: I answered to a message of the subject list. As this powerful discussion forum offers the option to change to thread view while reading the message and vice versa to message view I am not quite sure what I should have broken. In particular as this was not a long thread.

Anyway my intention was to see how Eu 4.0 (now rev 1378) works with wxEuphoria 12.1. Both work very fine so far with my OS (Windows Vista). The only minor problem I see is using global with Eu 4.0 in bigger sized applications.
