Question

我在Linux（32位）上编译了OpenSceneGraph 3.4.0，设置了OFF DYNAMIC_OPENSCENEGRAPH和DYNAMIC_OPENTHREADS标志，并在CMake上启用了应用程序和示例。

构建成功，我有静态库，并且示例osgstaticviewer正常工作。

然后我尝试使用静态库编译osgconv，使用从osgstaticviewer复制的CMakeLists.txt并修改添加obj支持和osgconv原始源文件。编译工作和生成的可执行文件工作，但我无法将obj文件转换为osg文件。特别是，如果我尝试命令：

./osgconv myModel.obj myModel.osg

我收到以下警告：

Warning: Could not find plugin to read objects from file "myModel.obj".
Error no data loaded.

关于静态osg插件的链接程序是什么？

在用于编译osgconv的CMakeLists.txt下面：

您需要修改osgconv的源代码，以使USE_OSGPLUGIN宏看到各种插件的绑定支持： http://trac.openscenegraph.org/projects/osg//browser/OpenSceneGraph/trunk/examples/osgstaticviewer/osgstaticviewer.cpp#L40

在Linux上静态编译osgconv并支持obj文件
