Sorry for late reply, <br>lately i'm doing QGis development under Linux Red Hat because of QGis installations <br>on Windows problems. It's going really well for Linux but sadly i still need to make a <br>development under
Windows because of some issuese. Based on your email, i already make <br>a new QGis installations on Windows from source. I'm using QGis 1.0 + Qt4.4.3, but i still<br>have no luck, this time i get different error:<br><br>undefined reference to `_imp___ZN12QgsMapCanvas9setExtentERK12QgsRectangle'<br>undefined reference to `_imp___ZN23QgsSingleSymbolRendererC1EN4QGis12GeometryTypeE'<br>CMakeFiles\timtut1.dir\main.cpp.obj In function `main':<br>make: *** [all] Error 2<br>make[1]: *** [CMakeFiles/timtut1.dir/all] Error 2<br>make[2]: *** [timtut1.exe] Error 1<br><br>Really hope your help in this matters because i already out of ideas about this errors.<br><br>Another questions, sorry because asking different question on same topic but if you think <br>i should make a new post for this question, i will do it as it should. Regarding my <br>development on Linux Red Hat, how can i load PostGIS layer into my QGis application? <br>This is my pieces of code about
how i do it:<br><br> QgsDataSourceURI * uri = new QgsDataSourceURI();<br>// set host name, port, database name, username and password<br> uri->setConnection("localhost", "5432", "postgis", "postgres", "postgres");<br>// set database schema, table name, geometry column and optionaly subset (WHERE clause)<br> uri->setDataSource("public", "klkv_poi2", "the_geom", "id=4");<br> QgsVectorLayer * mypLayerPoi = new QgsVectorLayer(uri->uri(), myLayerBaseNamePoi, "postgres");<br><br>This code give me error:<br><br>Layer Not Valid<br><br>Hope you can give me an advice for this matters.<br><br><br>Thanks in advance,<br><br>bonar<br><br></pre></blockquote></td></tr></table><br>
