前言

由于工程原因, 学习一下Ogre面向对象图形渲染开源引擎, 慢慢爬坑吧。首先还是环境的配置问题哎. 其实最重要的是要预先编译三方库, 虽然官方说可以自动编译, 但是在自己电脑上还是出现了无法解析外部符号之类的问题, 正常情况下我就认为是三方库的lib出现了问题, 最后额外编译三方库才得到了解决, 话不多说, 安装开始.

环境: windows10、VS2013、Ogre1.10

所需code:

官方网址: Ogre1.10(github)、三方库 、SDL2 、boost

【注】boost最好下载电脑所对应的VS版本, 我的电脑是VS2013, 所以下载boost_1_61_0-msvc-12.0-64.exe

安装

三方库配置

• 先安装boost, 一直下一步就行了, 我安装的位置是D:\Package\boost_1_61_0, 注意设置一下环境变量
  
  再看看我安装后的目录有哪些文件

  

• 新建一个文件夹Ogre1.10放置三方库以及后续的编译好的程序, 将三方库解压进来, 并在D:\Package\Ogre1.10\cabalistic-ogredeps-a337c4874a15\src新建文件夹SDL2, 将下载的SDL2压缩包中的大约40个文件复制丢进来, 并在D:\Package\Ogre1.10\cabalistic-ogredeps-a337c4874a15新建一个build文件夹, 接下来打开cmake-GUI, 设置好相关路径
  

  直接点击Configure, 截图一下我的结果

  
  
  
  
  调试日志如下:

  虽然全是红色的, 但是再Configure一下就没了, 如果还有红色的, 那你就得好好核对一下我上面贴的一堆图了. 随后Generate一下, 就看到build文件夹下已经有完整的VS工程啦
  

  然后打开OGREDEPS.sln, 对ALL_BUILD生成一次, 就发生问题了

  错误    944 error MSB6006: “cmd.exe”已退出，代码为 1。  C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\Microsoft.CppCommon.targets  170 5   SDL2

  这时候就考察VS的调试功底了, 直接去输出窗口看具体位置:

  5>  Move SDL2 install files into the Release and Debug folders.
  5>  CMake Error at D:/Package/Ogre1.10/cabalistic-ogredeps-a337c4874a15/build/src/SDL2-prefix/src/SDL2-stamp/SDL2-MoveInstallFiles-Debug.cmake:16 (message):

  很清晰地发现错误日志已经被丢到SDL2-MoveInstallFiles-*.log中, 去瞅一眼

  Error copying file "bin/SDL2.dll" to "bin/Debug/SDL2.dll".
  CMake Error at D:/Package/Ogre1.10/cabalistic-ogredeps-a337c4874a15/build/src/SDL2-prefix/src/SDL2-stamp/SDL2-MoveInstallFiles-Debug-impl.cmake:29 (message):
  Command failed (1):'C:/Program Files/CMake/bin/cmake.exe' '-E' 'copy' 'bin/SDL2.dll' 'bin/Debug/SDL2.dll'

  很多人看到这类英文错误就直接问人, 小兄弟啊, 遇到错误先认真看一遍, 至少先翻译一下也行啊. 嗯, 闲话不多说, 这个问题就是复制SDL2.dll的时候出问题了, 三方库的输出目录是D:\Package\Ogre1.10\cabalistic-ogredeps-a337c4874a15\build\ogredeps, 可以发现在bin下的确有SDL2d.dll躺着, 主要是由于我们编译的是Debug模式. 所以没找到SDL2.dll, 导致错误, 解决方法很简单, 切换Release模式重新编译, 或者手动把这个文件拷贝进去.建议两个都做一遍, 反正不冲突.

• 最后对INSTALL生成一遍,一定要核对一下相关文件(VS工程中出现的那几个三方库)是否在ogredeps文件中, 主要有
  include: 相关头文件, 这个一般都存在
  lib: 相关lib库文件
  bin: 相关dll库文件
  如果不在, 直接针对每个项目右键打开文件资源管理器, 找到以后复制过来.

编译Ogre源程序

• 将ogre-master解压到D:\Package\Ogre1.10中, 然后将刚才编译的三方库ogredeps放入到ogre-master中, 并更名为Dependencies, 在D:\Package\Ogre1.10下新建文件夹Ogre用于存储编译的Ogre, 在cmake-gui中设置路径
  
  然后Configure, 调试信息太多了, 就不贴了, 第二次Configure出现错误

  send_errorD:/Package/Ogre1.10/Ogre/Dependencies/bin/debug/cg.dll did not exist, can't install!
  send_errorD:/Package/Ogre1.10/Ogre/Dependencies/bin/release/cg.dll did not exist, can't install!

  这个文件在刚才编译三方库的时候D:\Package\Ogre1.10\cabalistic-ogredeps-a337c4874a15\build\bin里面, 同时我们还发现另外两个dll: OIS.dll和Remotery.dll, 保险起见都复制过去吧,两种模式Debug和Release, 重新Configure就没问题了, 调试日志如下

Generate一下, 生成VS2013的工程文件, 可以在D:\Package\Ogre1.10\Ogre中找到.
【注】上述过程也可以在Cmake-GUI中不勾选OGRE_BUILD_DEPENDENCIES,并且设置OGRE_DEPENDENCIES_DIR为你的三方库目录, 好像更快一些
- 编译OGRE.sln, 先ALL_BUILD一下, 时间挺久的, 要盯着错误列表, 一旦出现错误, 就直接取消生成解决错误吧. 个人觉得很多人会出现外部符号无法解析问题, 一定是由于lib文件没折腾好引起的. 重新仔细核对上述步骤, 尤其是核对dll和lib是否折腾对.
【注】这里贴一下我编译好的三方库,便于大家核对 :链接：http://pan.baidu.com/s/1boDvokv 密码：lkap
然后就可以INSTALL啦, 这个就是生成我们后续开发需要引用的Ogre各种文件, 存在于D:\Package\Ogre1.10\Ogre\sdk目录下, 以后开发就只需要它应该就可以了.

• 最后可以通过VS运行程序, 也可以通过D:\Package\Ogre1.10\Ogre\bin\debug\SampleBrowser_d.exe运行程序
