在Windows上无法使用OSG和GDAL

Question

我在Windows 10 x64上工作

IDE：QtCreator 4.8.0基于Qt 5.12.0（MSVC 2015,32位）

如果需要，我的.pro文件的内容就在最底层。

有一个最小的OSG样本（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();
}

在上面的代码中，您可以看到我在哪里设置断点。

所以：

在注释OGRPoint p;的情况下：它编译，运行，停止在“断点2”，当我前进它显示飞机（模型“cessna.osg”）。这是正确的行为。

如果没有注释OGRPoint p;：它编译，运行并忽略两个断点。它没有显示任何东西。好像我的main什么都没有。如果我在Linux上这样做，那么它工作正常。为什么会发生？

.pro文件，如果它影响：

Answer 1

问题是库需要libgdal-20.dll才能工作。我没有指定.dll的路径。所以我通过将.dll文件复制到带有二进制文件的文件夹中解决了这个问题。现在它工作正常。
