osg 3.4.0编译安装

下载OpenSceneGraph-3.4.0.zip

1) unzip OpenSceneGraph-3.4.0.zip

2) cd OpenSceneGraph-3.4.0

3) mkdir build

4) cd build

5)在build中和编译vtk一样，都是用cmake写的,所以

build目录下：ccmake ..

build目录下：sudo make

build目录下：sudo make install

6)在.bashrc 或者etc/profile中写入：
export PATH=${PATH}:/home/######/soft/OpenSceneGraph−3.4.0/build/bin

export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/home/######/soft/OpenSceneGraph-3.4.0/build/lib

export OSG_FILE_PATH=/home/######/soft/OpenSceneGraph-3.4.0/build/OpenSceneGraph-Data

@ /######/ 为home目录

7)osgversion 查看版本—–>是否安装正确

遇到问题 osgversion: error while loading shared libraries: libosg.so.130: cannot open shared object file: No such file or directory

解决办法:

locate libosg.so.130 —>显示位置 /usr/local/lib64/libosg.so.130

cd /etc

etc目录下 sudo kwrite ld.so.conf ——>添加一行 /usr/local/lib64

etc目录下 sudo ldconfig

————————————无比华丽的分割线————————————

linux下osgocean编译
1) github下载osgocean-master
2) fftw 编译（百度）
3) 解压osgocean-master
4) osgocean-master目录下 mkdir build
5)osgocean-master/build/目录下
ccmake ..
make
make install

出现的错误

按照上面地址修改osgocean-master中的代码
osg3.4按照osg3.5修改
