Can you make this publicly available? Maybe put into the repo?

Okay I just made a repository for this demo/test project - https://gitlab.com/apoorv569/cpp-projec ... /wxDvcTest

[doublemax]

Thanks. I haven't built it myself yet, but please try these things:

1) remove App constructor and destructor completely
2) app.h - instead of #include <wx/app.h>, #include <wx/wx.h>
3) mainframe.hpp - remove include #include <wx/defs.h>, frame.h, gdicmn.h, include <wx/wx.h> first

How do you link sqlite?

Hi,
Basically what doublemax says - you need to follow the wxWidgets samples.

Thank you.

I tried all steps no luck.

How do you link sqlite?

I have set sqlite as a dependency in `meson.build` it auto find the library and links to it.

Code: Select all

sqlite3 = dependency('sqlite3')

In the meanwhile i tested under Windows using the sqlite amalgamation and it worked fine.

As i usually don't work under Linux, testing under Linux might take a while, but i'm starting to suspect that it would work too and that there is something wrong with your build setup.

I have no idea what Meson does behind the curtains, but i would try to build the sample without it and check if it makes any difference.

Okay I tried compiling it manually, looking around the internet this is what I found how to link and compile wx and sqlite using g++

Code: Select all

g++ app.cpp `wx-config-gtk3 --libs --cxxflags` MainFrame.cpp `wx-config-gtk3 --libs --cxxflags` -l sqlite3

I hope this is the right command, it does compile successfully and creates a `a.out` file, which when I run is causing the same problem as before.

Hi,
And I presume you are using the pre-built library from the OS repository?

I didn't see anything wrong with the way you compile.
Although I would prefer:

Code: Select all

g++ *.cpp -o test `wx-config --cxxflags --libs` -lsqlite3

Thank you.

So i managed to build this under LInux (wx3.1.4), and to me it seems that the event handler is called, but just the std::cout stops working. Because when i replaced that with a wxLogMessage(), it showed up.

Please check that on your side.

Yes, I installed the library from OS repository, I did not compile it myself. Though on my system there is no `wx-config` but there is `wx-config-gtk3` I assume `wx-config` is for GTK 2, and I installed the `wxgtk3` package.

Yes I replaced the std::cout with wxLogMessage(), and the popup shows up with the message fine. Why does std::cout stops working after adding a entry to wxDVC though.

No idea. Maybe sqlite does something internally that breaks it. Although that should be very unlikely, because a) sqlite is widely used and b) it's pure C, not C++

I found some posts where people are saying that std::cout is a buffered output and might get stuck after a while, and should use std::cout.flush() to flush the buffer, I tried this but no luck. Is there a wx inbuilt function to print to the console instead, wxLogMessage shows a popup, is there a alternate that does not open a popup and prints to console.

Try wxLogDebug

Or, if wxLogDebug() output is consumed by the debugger and may not be shown (e.g., gdb on MSW), one can try good old wxPrintf(). However, this probably won't be shown on MSW.
