Can't open a dialog from custom plugin

[underdoeg]

Hi

I am working on a plugin for codelite that works a little bit like a project wizard. To do so, I have created a custom dialog that extends wxDialog.

And then when selected in the menu, I am showing it like this:

Code: Select all

void ofMaker::onNewOf(wxCommandEvent& e)
{
	//but its a modal dialogue for now
	OfDialog* ofDialog=new OfDialog(m_mgr->GetTheApp()->GetTopWindow());
	ofDialog->Show();
}

Now when I activate the plugin and select it in the menu, I get the following error:

Code: Select all

codelite: symbol lookup error: /usr/lib/codelite/OfProjectMaker.so: undefined symbol: _ZN8OfDialogC1EP8wxWindow

The dialog works though when I run it as a standalone wxWidgets application.

Code: Select all

#include <wx/wx.h>
#include "ofdialog.h"

// application class
class wxMiniApp : public wxApp
{
    public:
		// function called at the application initialization
        virtual bool OnInit();

		// event handler for button click
        void OnClick(wxCommandEvent& event) { GetTopWindow()->Close(); }
};

IMPLEMENT_APP(wxMiniApp);

bool wxMiniApp::OnInit()
{

	OfDialog ofDialog(NULL);
	ofDialog.Show();

	// enter the application's main loop
    return true;
}

Will be happy about any ideas. thx.

Can you post the code of your Dialog? it seems like the constructor of the dialog is missing..
You can run from a command line:

Code: Select all

c++filt _ZN8OfDialogC1EP8wxWindow

and it will tell you what symbol is missing (in your case: a constructor that accepts wxWindow)

thanks

yes, you are right. I have a second cpp file with the class in it. It looks like this one is not being compiled, although I have it in my project.
So I copied all the contents of ofdialog.cpp into ofmaker.cpp (the main plugin code) and then it worked just fine. So the code is alright, it just doesn't get compiled.

It'd still be useful to keep this code separated. Any hints what I might be doing wrong?

I am not sure how you are compiling / OS
I will need to see the project file / build log in order to answer that question

I am on linux ubuntu 64bit.

I have the project hosted on github if you want to take a look at it: https://github.com/underdoeg/ofProjectM ... r-CodeLite

With the hack I mentioned it all works fine. But it is a little bit ugly because now I have double code...

thank you

As a quick tip, remove the following files from git, those are auto-generated and there is no sense of keeping them under source control:

- ofProjectMaker.tags
- ofMaker.mk
- ofProjectMaker.workspace.session
- ofProjectMaker_wsp.mk

When developing a plugin for codelite under Linux, you should be using codelite's configure script and not the codelite build system since codelite itself is being built using a custom makefile under linux. (this allows people to build codelite from scratch without the need to have codelite installed first)

Just open the file 'configure' and follow one of the other plugins (e.g. 'CodeFormatter')
You should be adding 3-4 entries (copy the CodeFormatter ones and replace it with your plugin)

Once you completed that, run './configure && make'

1) compile a codelite or install one
2) create an installation root: mkdir -p /home/username/somepath
3) checkout codelite sources, and run the configure as follows: ./configure --enable-debug --prefix=/home/username/somepath
4) make && make install

The last command will compile and will install codelite under /home/username/somepath
You can not set the target binary for debugging to /home/username/somepath/bin/codelite

thanks for the tip. I wasn't sure which files are actually auto generated. Good to know!

I did develop the plugin according to your manual here: http://codelite.org/LiteEditor/CreatingNewPlugin

And now I know what I did wrong. I didn't rerun the configure script after adding the new cpp file. Quite an obvious error now...

Congrats for your easy plugin system btw! It took almost no effort to add another context menu and stuff

Thanks for your help, I realized it while reading your answer.

Just some other question: When I compile a plugin on ubuntu 64bits. Should it run on other linux distributions like arch linux as well?

When I compile a plugin on ubuntu 64bits. Should it run on other linux distributions like arch linux as well?

Usually, when I am developing under Linux, I am providing a pre-compiled binaries per distro ( to be more accurate: I am building the codelite's .deb for Ubuntu32/64, while DavidGH is building the packages for OpenSUSE, FC, Redhat and some other distros )

The point is: you will need to build it for each distro, since the version of the various dependencies (wxWidgets, gtk etc) is different per distro.
