Can't use OSG with GDAL on Windows


I work on Windows 10 x64

IDE: QtCreator 4.8.0 Based on Qt 5.12.0 (MSVC 2015, 32 bit)

Content of my .pro file is at the very bottom if it's needed.

There is a minimal OSG sample (main.cpp):

#include <osgDB/ReadFile>
#include <osgViewer/Viewer>
#include <ogrsf_frmts.h>

int main(int argc, char *argv[]) {
   // OGRPoint p; //breakpoint 1
    osg::ref_ptr<osg::Node> root = osgDB::readNodeFile("../resourses/cessna.osg"); //breakpoint 2
    osgViewer::Viewer viewer;
    viewer.setSceneData(root.get());

    return viewer.run();
}

In the code above you can see, where i set breakpoints.

So:

In case with commented OGRPoint p;: It compiles, runs, stops on "breakpoint 2" and when i go forward it shows the airplane (model "cessna.osg"). This is correct behavior.

In case with uncommented OGRPoint p;: It compiles, runs and ignore both breakpoints. It doesn't show anything. As if i had nothing in my main. If i do it on Linux, then it works fine. Why does it can happen?

.pro file, if it affects :

# any Qt feature that has been marked deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the

# You can also make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.

Solution

  • Problem was that the library needed libgdal-20.dll to work. I didn't specify the path to the .dll. So i resolved this problem by copiyng the .dll file into folder with binaries. Now it works fine.
