compiling wxThings and wxPlotCtrl
in [wxWindows]
|
From: samuelvoiron on 4 Apr 2007 08:42 Hello crazy wxCoders !! I copy/paste here an e-mail I've sent to John Labenski, in case other guys have any idea to help me... Thanx ;) First of all thank you very much for the job you've done on some wxWidgets modules. Excuse for this long E-mail but I really need some help on some of the modules you've developped. I decided to use this library for my end-of-study project which consists of a C++ program. I'm working on windowsXP with VisualC++ExpressEdition (free) and I've had some hard time compiling some of the component of wxCode you've developped. The module I want to use is wxPlotCtrl which seems really powerfull and would suits pretty well my needs for the application I'm programming. (a network sniffer with realtime plot for several quantities such as bitrate, delay, etc...) I checked out the CVS of wxCode and noticed I need wxThings for compiling and using wxPlotCtrl. When I look at the wxthings.dsw VC++ project properties, it is set for a dll compilation (with use of wxWidgets dll's). Since I compiled wxWidgets as static libs, I change all settings for this project from 'dll' to 'lib' (directories names and else). I compile and everything seems fine (a things.lib is created where expected) and I decide to compile the wxtings sample. I have to change some other project properties for the sample as well (dll to lib). In the additional lib's I see "wxcode_msw28d_things.lib" which is not found at compilation so I replace it with things.lib. I also remove preprocessing definition variables which name contains DLL in it... Oh and I also changed wxmsw28d.lib (which I don't have anywhere) to wxmsw28d_core.lib (which is in the $(WXWIN)/lib/vc_lib/ directory) But the compilation ends in a lot of errors (2000 so far, I can't stop the process...) mainly saying "unresolved external symbol" in the wxmsw28d_core.lib file. I also compiled wxPlotCtrl which dsw file is set already to static lib (why by the way having things configured in dll and plotctrl in lib?). So I don't problems having the plotctrl.lib file but the sample doesn't work either... Sorry for this long E-mail and for tha fact I'm quite a beginner in C++ programming on windows. I started trying using wx on Linux but didn't digg much further since my project will have to be developped in Windows anyway... I switched from different wxWidget versions (2.6, 2.8.2, 2.8.3, CVS...) but can't work it out. Thanx for your help as much as you understand my request... =) Cheers from Toulouse, France Sam
From: Samuel on 4 Apr 2007 11:26 Ok I understood a few things... like the newbie errors I've made... So I erased all instance of the Widget lib on my hard drive and downloaded the last stable (2.8.3) from their website. I compiled it with no problem (still using VC++Express) in Debug AND release (one day my killer app might need a release...) I even tried a sample (minimal) and it worked !! =) I assume all samples will... I'll play with these later. I then went on wxThings which agreed to compile as well (debug and release)... I understaood here my newbieness when I noticed the 'configuration manager'... anyway. Here comes the black dot... Compiling thingsdemo says : (translation from french) "couldn't open program database in thingsdemo.pdb" and failed =( Ok nevermind, the lib I really need (and the sample) is PlotCtrl so I go to this now. No problem building (ok not just compiling, I'm newbie, sorry) the lib in both release and debug. And for the sample, here is what I get : fatal error LNK1104: couldn't open file 'wxmsw28d.lib' So as I realise I, indeed, don't have it in the WXWIN/lib/vc_lib dir, I change it to wxbase28d.lib (and w/ d for the release) in the project properties. And then is a huge flow of errors I manage to stop by quickly clicing stop (ok that was the toughest...=) The errors say mainly things like: unresolved external symbol "protected: static struct wxEventTable const wxFrame::sm_eventTable" ? sm_eventTable(a)wxFrame@@1UwxEventTable@@B) wxplotctrl.obj So I guess I'll start trying to use the PlotCtrl lib without the sample... but I'd feel probably more secure understanding how to fix those blury strange errors... (And security is a feeling the french people like very much in those times of presidentiel election...)

(database problem...??) 2nd point: would you know how to zoom OUT in the PlotCtrl sample ...? or how to implement it in the source... (I'll have a look at it...) Thanks, Samuel

You must link with at least > wxbase and wxcore and often some others. and wxCode components assume you have an env var called WXWIN which points to the folder of your wxWidgets. If you use makefiles you can tell them what is the folder without using WXWIN env var (by using WX_DIR option). IDEs are not as flexible as makefiles thus they have WX_DIR=WXWIN hardcoded.
