在Linux上静态编译osgconv并支持obj文件

Question

我在Linux（32位）上编译OpenSceneGraph 3.4.0，设置OFF DYNAMIC_OPENSCENEGRAPH和DYNAMIC_OPENTHREADS标志并启用CMake上的应用程序和示例。

构建成功，我有静态库，也是例子osgstaticviewer正常工作。

然后我试图编译osgconv使用利用osgstaticviewer抄的CMakeLists.txt只有静态库和修改添加OBJ支持和osgconv原始的源文件。编译工作和生成的可执行文件，但我无法将obj文件转换为osg文件。特别是，如果我尝试的命令：

./osgconv myModel.obj myModel.osg 

我得到以下警告：

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

什么是用于连接静态OSG插件程序？

下方的CMakeLists.txt用来编译osgconv：

您需要修改osgconv源已经看到约束力的各种插件这里支持USE_OSGPLUGIN宏： http://trac.openscenegraph.org/projects/osg//browser/OpenSceneGraph/trunk/examples/osgstaticviewer/osgstaticviewer.cpp#L40
