<br><br>>Hi Godofredo,<br>>thanks for your hints. I'll tru it as soon as possible.

<br> Hi Giovanny:<br>
<br>
You can use the libs and includes bundled with osgeo4w to build qgis and<br>
grass plugin.<br>
<br>
Using osgeo4w do the following:<br>
<br>
install grass from desktop category<br>
install grass-devel-vc from libs (be sure is the same version that grass ) <br>
install gdal from libs<br>
install geos from libs<br>
install sqlite from libs<br>
install proj from libs<br>
install xpat from libs<br>
install gsl from libs<br>
<br>
create the environment variable LIB_DIR pointing to c:/osgeo4w and run<br>
cmakesetup, after that set GRASS_PREFIX to the grass instalation directory<br>
(something like c:/osgeo4w/apps/grass/gras-6.4.0R3)<br>
<br>
And thats all, start compiling with visual studio or nmake<br>
<br>
Hope this helps<br>
<br>
Regards <br>
Godofredo Contreras<br>

Subject: [Qgis-developer] build qgis-grass plugin on Windows<div><div></div><div class="h5"><br><br>Hi. I'm going on with my battle to compile qgis+grass on windows vista... very frustrating!<br>I've almost finished to compile grass under mingw, as AFAIK it's the only way to do it. Am I wrong?<br>
I've built its various dependencies (like GDAL, proj, libtiff, freetype, etc.) under ingw too.<br>Now, what to do with QGIS? I know it should be compiled with MSVC, at least it's the way choosen for OSGeo4W stack. So I should rebuild GDAL, and all the rest of the stuff, with MSVC? And, at the end, how to build the grass-qgis plugin? Isn't it a problem having compiled the various parts with different systems?<br>
<br>Ok, I admit, I'm a bit confused working on Windos. Linux is more linear to me! :)<br><br>Giovanni<br><br></div></div><hr>Windows Live™ Contacts: Organize your contact list. <a href="http://windowslive.com/connect/post/marcusatmicrosoft.spaces.live.com-Blog-cns%21503D1D86EBB2B53C%212285.entry?ocid=TXT_TAGLM_WL_UGC_Contacts_032009">Check it out.</a></div>
