osg源码编译步骤

1、最基础的库zlib

2、libjpeg；http://blog.csdn.net/dgyanyong/article/details/22970213

3、libtiff；http://blog.csdn.net/chunxiaopengshan/article/details/4038368

With Microsoft Visual C++ installed, and properly configured for commandline use (you will likely need to source VCVARS32.BAT in AUTOEXEC.bAT or somewhere similar) you should be able to use the provided makefile.vc.

C:\LIBTIFF\LIBTIFF> nmake /f makefile.vc
C:\LIBTIFF\LIBTIFF> cd ..\tools
C:\LIBTIFF\TOOLS> nmake /f makefile.vc

This will build the library file  LIBTIFF\LIBTIFF\LIBTIFF.LIB . This can be used in Win32 programs. If used in a project using the /MD compiler switch (using the runtime C library), it may be necessary to modify the CFLAGS macro in makefile.vc to correspond.

The makefile also builds a DLL (libtiff.dll) with an associated import library (libtiff_i.lib). Any builds using libtiff will need to include the LIBTIFF\LIBTIFF directory in the include path.

The libtiff\tools\makefile.vc should build .exe's for all the standard TIFF tool programs.

NOTE: The contents of the contrib/win32 directory should no longer be needed, and are kept in the distribution temporarily.

4、libpng；http://blog.csdn.net/yshen_dublin/article/details/4942871

以上三库均需依赖zlib库；

5、核心库OpenThreads，以获得多线程支持；

6、osg源码可以从osgwiki官网下载；
