编译最新的present3D应用程序

present3D是什么

这个在google上很容易找到,这里就不翻译了。

如何获取present3D

svn，或是二进制present3D当然OSG里面也有...但是好像功能不全.

我编译present3D使用的库

present3D svn trunk上的源代码，

sdl1.2.5

libxml 2.8.9 win32

iconv 1.9.0

最后不要忘记在编译器的release和debug模式中添加Ws2_32.h

开始编译

如果不了解开源库的编译，参看我的另一篇文章

（1）使用CMake

（2）Visual Studio，bach build。。。。

请始终记住，缺什么，给什么。

我再编译过程中遇到了一些严重问题：

当我在Visual Studio上编译时，刚开始报错error c1083: encoding.h无法找到iconv.h，路径错误

后来我会到present3D给我的下载网站上继续看。。。发现我少下载了一个依赖。就是iconv，我把它下载下来配置好路径，编译。

第二个错误，

通过这次学习，我终于发现了，lnk2019报错的显示方式是：先提示外部符号是什么，最后再提示用户这个符号在那个函数中被引用。
