How to use the plugins of old SDK for new CodeBlocks?

[gonboy]

Hello:
I have some old plugins for Codeblocks? But the plugins is stop developping and I couldn't find the source.

I copy the plugins (*.dll and *.zip)to my build Codeblocks,to run app.
show some info like below:
==============================================
one or more plugins were not loaded.
this usually happens when a plugins is build for a different version of the Code::Blocks sdk
check the application log for more info
==============================================
How Can I use the old plugins for my Codeblocks?

Unlikely that you will be able to get the old binaries to work. They will need to be tweaked for changes in the SDK and recompiled. What plugins are they? Do you have sources?

I think there is no such way.

The newer Codeblocks (SDK) has some interface changed, which means you can't use the old plugins for the new interface. I think the only way is : you find the plugin's source, and build them against the newer SDK.

Couldn't find source! That's previous enginerr's plugin,he leave office.


the Codeblocks how to find the plugins isn't suitable for App?

Can I change *.dll or *.zip ,
eg
change some version bytes to cheat the APP?

I had been working on the following patch.  It adds an option to tell Code::Blocks to ignore version numbers and load plugins anyway.  You can test it if you like.  (Be warned that just because this allows the plugin to be loaded does not mean it will actually work.)

Oh dear... why would you want to do this?! You basically screw our crash protection in case the SDK changes.

This will definitely not make it into trunk. For re-compiling 3rd party plugins in an easy way if really needed (in case SDK version changed) I've prepared an article in the WiKi based on nightly builds. An alternative is always to wait for the next nightly.

For 3rd party plugin developers I can offer the following in advance:
If their repo is based on subversion we can integrate it as remote repository into the main C::B repo. Then it remains independent but people can easily have the sources from one place. (Like we did with the FortranProject plugin for example).

Surely this requires maintaining the plugin to at least SDK compatibility. If a 3rd party plugin seem dead one can ask to take ownership of an existing repo to continue development.

I Check the DLL file.
Codeblocks couldn't
    wxDynamicLibrary* LoadLibrary(const wxString& filename)
so failed.
=============================================
    wxDynamicLibrary* LoadLibrary(const wxString& filename)
    {
        Libs::iterator it = s_Libs.find(filename);
        if (it != s_Libs.end())
        {
            // existing lib./codeblocks
            it->second.ref++;
            return it->second.lib;
        }
        // new lib
        it = s_Libs.insert(s_Libs.end(), std::make_pair(filename, RefCountedLib()));
        it->second.lib = new wxDynamicLibrary;
        it->second.ref = 1;
        it->second.lib->Load(filename);
        return it->second.lib;

I was not planning on submitting it.  My purpose was simple convenience for not having to relink my plugins as often.  (And it has a checkbox - off by default .)

I Check the DLL file.
Codeblocks couldn't
    wxDynamicLibrary* LoadLibrary(const wxString& filename)
so failed.                        .

I sort of expected as much... my patch does not have any magic code in it.  All it does is let Code::Blocks try to load the plugin.
If you do not have access to the plugin's source, it seems your only real option to use the plugin would to stay with an older version Code::Blocks.
