Re: [Qgis-User] QGis (Windows) Customization Help
Hi 2007/2/26, Elavazhagan.M <[EMAIL PROTECTED]>: Hi Martin, please clarify the following scenarios: 1. For dynamic linking, I need to know the classes available in the DLL I'm linking. Am I correct? If so, where can find such documentations? All the header files are available in the QGIS sources in svn. In the next stable release (0.8.1) I am bundling them in with the installer too. QGIS is open source everything is there for you to look at when you want to! 2. If I should link to the DLLs dynamically, what's the need of building my own QGis (creating .lib files)? And, why can't I dynamically link to the existing DLLs available under the QGis installation folder? You cant link MSVC apps to the dlls shipped with QGIS since QGIS is built using mingw/gcc which uses different symbol decorations to MSVC. Regards Tim Thanks.

I hope you mean "Static Linking" and not the "Dynamic Linking". Am I right Martin? Plugins link dynamically to QGIS libraries as those are DLLs, not static libs. Is there any reason to link them statically? Martin ___ Qgis-user mailing list Qgis-user@lists.qgis.org http://lists.qgis.org/cgi-bin/mailman/listinfo/qgis-user

In case you'd like to develop with Visual C++, you'll need to compile QGIS by yourself to obtain library files - we compile QGIS with MinGW and its library files are incompatible with those in VC++. Also you'll need to compile QGIS dependencies first to be able to link QGIS with them. To avoid this you can use MinGW compiler and MSYS environment we use which contains all dependencies, thus making compilation much easier. http://qgis.org/uploadfiles/msys/msys.tar.gz (269 MB) Or Do I need to link those DLLs dynamically from my Plug-in code? Yes, you need to link your plugin to QGIS libraries. Or finally, you can try out current development version that introduces plugins in Python language. This means no dark magic with (re-)compilation, less code and simpler debugging. Martin ___ Qgis-user mailing list Qgis-user@lists.qgis.org http://lists.qgis.org/cgi-bin/mailman/listinfo/qgis-user

Re: [Qgis-user] QGis (Windows) Customization Help
Hi Take a look at our blog http://blog.qgis.org where you can find various tutorials including one on writing your first plugin by Marco Hugentobler. There is a perl script under src/plugins/plugin_build.pl that will create the framework for a new plugin but at this point in time it works only on mac and linux platforms. Otherwise you can just clone an exising simple plugin or use the plugin_template as a starting point.
