OGRE 编译笔记

一时兴起，就编译一下 OGRE。编译流程没什么特别，就是 cmake 生成 Makefile 然后编译，选择 MinGW 作为编译器。

问题1：依赖第三方库文件

这次本来用的是 OgreDependencies_MinGW_20100216.zip 来解决依赖库的问题，但之后就出现问题了。MinGW 的版本与这些文件原来的版本不一致。

错误信息截选：

E:\devel\ogre\Dependencies\lib\release\libFreeImage.a(Plugin.o):Plugin.cpp:(.text+0xaf5): undefined reference to `__gxx_personality_sj0'
E:\devel\ogre\Dependencies\lib\release\libFreeImage.a(Plugin.o):Plugin.cpp:(.text+0xb17): undefined reference to `_Unwind_SjLj_Register'

E:\devel\ogre\Dependencies\lib\release\libFreeImage.a(BitmapAccess.o):BitmapAccess.cpp:(.text+0xdd1): undefined reference to `__gxx_personality_sj0'

大致的意思 MinGW 用的异常处理库不一致，要么重新编译这些库，要么换个版本的 MinGW。

那就编译一下 FreeImage 吧。

1 下载： ：http://cdnetworks-kr-1.dl.sourceforge.net/project/freeimage/Source%20Distribution/3.15.3/FreeImage3153.zip

2 解压编译： make -f Makefile.mingw

无奈又有错误了，错误信息：

Source/LibRawLite/./src/libraw_datastream.cpp: In constructor 'LibRaw_windows_datastream::LibRaw_windows_datastream(cons
t TCHAR*)':
Source/LibRawLite/./src/libraw_datastream.cpp:474:15: error: 'runtime_error' is not a member of 'std'

make: *** [Source/LibRawLite/./src/libraw_datastream.o] Error 1

好吧，加上

#include <stdexcept>

还有宏

#define WINVER 0x0500

需要静态库，设置一下

set FREEIMAGE_LIBRARY_TYPE=STATIC

这样就可以了，把编译好的 FreeImage.a 复制到 Dependencies 目录下，改名为 libFreeImage.a。

问题2：rc 文件编译问题

错误信息：

原因分析：大致是 windres 的参数有问题吧，暂时把参数去掉编译看看，后面有时间再仔细研究一下。

不得不感慨一下，编译过程实在煎熬，单进程编译消耗的时间太长，看来需要试试并行编译。
