Python plugin
« on: January 08, 2019, 01:50:31 pm »
I attempted to build the python plugin, i.e.

https://github.com/spillz/codeblocks-python

(which looks awesome). However, build fails with the following error:

Code
XmlRpcEvents.cpp -o .objs/XmlRpcEvents.o
rm -f libXmlRpcEmbedder.a
ar -r -s libXmlRpcEmbedder.a .objs/ExecHiddenMSW.o .objs/XMLRPC/src/XmlRpcClient.o .objs/XMLRPC/src/XmlRpcDispatch.o .objs/XMLRPC/src/XmlRpcServer.o .objs/XMLRPC/src/XmlRpcServerConnection.o .objs/XMLRPC/src/XmlRpcServerMethod.o .objs/XMLRPC/src/XmlRpcSocket.o .objs/XMLRPC/src/XmlRpcSource.o .objs/XMLRPC/src/XmlRpcUtil.o .objs/XMLRPC/src/XmlRpcValue.o .objs/xmlrpc_embedder.o .objs/XmlRpcEvents.o

                  ^~~~~~~~~~~~~~~

I then googled and found this

https://forums.wxwidgets.org/viewtopic.php?t=22962

However, (some time ago) I tried fixing this and then found other errors, I guess this is generally due to changes in wxWidgets (plugin depends on v2?). In general, does anyone know if anyone is working on this plugin? I left a github issue but the author never responded. I feel like someone experienced with the plugin system, codeblocks and wxWidgets could probably fix this in about 20 minutes.

I made a fork and began making some fixes here:

https://github.com/crobarcro/codeblocks-python

one of the issues with the plugin is the definition of some constants is missing:

Code

I presume at some point these were defined somewhere in the code provided by codeblocks, but are no longer present. Can anyone tell me if there are appropriate replacements for these?

Ok, I realised I needed to change _KEYMOD_ to _SCMOD_

Now I get the following errors:

It seems like the correct library is not being linked, all errors are related to wxAUI. Can anyone tell me what I need to link to to get rid of these undefined reference errors?

Our developer dmoore is the maintainer of this plugin, so hope he can help. :)

If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.

@crobar

Just saw the Github readme on that plugin and I also think that it looks great. I greatly appreciate your efforts and saw that you had cloned the project to get it working. I had been checking wiki, the original github and the posts in the forum but I have found no trace of information that showed someone was actually working with that pluing(sadly).
 
So when I read your post, the reason nobody is using is might be that its impossible to compile it in the first place? So I really appreciate your efforts and stammina to resolve that and I hope you will succeed!
Just now I tried to download and compile it myself. I could open the workspace but then got stuck at multiple places. The descriptions and files raise so many additional questions for me (just a mid range programmer) that it seems like a long journey to follow all leads down to the basics to get it to run. Additonally I am totally new to Python which seems a bad prerequisite  :(. 

So should you ever succeeded to get it running I would be very interested to lean how to do it myself. Juding from your posts above you have come quite far already.
Sadly, I can not offer much to help. However I can offer to update the wiki with step-by-step instructions on how to get that plugin running.


PS: Maybe in that process I understand why it is so difficult to distribute a CB plugin as independent binaries from the CB versions (for me that was the whole point about plugins). But maybe this one is very special.

Definitions starting with wx is wxwidgets and SCI is I guess scintilla. The current github version of wxwidgets doesn't even have wxscintilla.h so make sure everything is correct with wxwidgets version. My guess is that wxscintilla.h has (should have) those definitions so check it.
