编译/链接windows的blender

Question

我在链接windows的blender时遇到问题。我正在使用CMake和mimgw编译器（mingw32-g++.exe c++编译器）和（mingw32-gcc.exe c编译器）创建我的makefile。

我正在从
获取来源https://svn.blender.org/svnroot/bf-blender/trunk/blender
https://svn.blender.org/svnroot/bf-blender/trunk/lib/windows
如
中所述http://wiki.blender.org/index.php/Dev:2.5/Doc/Building_Blender/Windows/MinGW/CMake

所有链接错误都与lib\windows\gcc有关
以下是其中的几个：

lib\windows\gcc\tif\lib/libtif.a（tif_pixarlog.o）：（.text+0x172d）：未定义对`deflateInit_'的引用

lib\windows\gcc\openimageio\lib/libOpenImageIO.a（sysutil.cpp.obj）：sysutil.cpp：（.text+0x32）：对的未定义引用`GetProcessMemoryInfo@12'

lib\windows\gcc\openimageio\lb/libOpenImageIO.a（socketinput.cpp.obj）：socketinput.cpp：（.text+0x45c2）：对的未定义引用`WSASetLastError@4'

在我的lib\windows\gcc\openimageio中有一个批处理文件（oiiobuild.bat），我猜这是由CMake 生成的

cmake ..oiiosrc -G "MinGW Makefiles" ^
    -DBUILDSTATIC=1 ^
    -DBOOST_CUSTOM=0 ^

    -DUSE_FIELD3D=OFF ^
    -DUSE_QT=OFF ^
    -DUSE_PYTHON=OFF ^
    -DCMAKE_BUILD_TYPE=Release
mingw32-make install

原来lib\windows\gcc\oiio不存在。

编辑：试图用scons编译blender 2.71，我发现如果我不从blender文件夹运行python，我会得到*找不到SContruct文件。错误

所以

使用python26\python.exe scons/scons.py我得到

    env['DLIBCOM'] = '$DLIB $_DLIBFLAGS {} $TARGET $SOURCES $_DLIBFLAGS'.format('-c' if env['PLATFORM'] == 'win32' else '')

使用python27\python.exe scons/scons.py我得到

Answer 1

CMake+Mingw32已经很长时间没有经过测试了，但SCons+Mingw64确实有效，因为Blender构建机器人也使用它进行夜间构建：http://builder.blender.org/buildslaves/mingw64_scons_anthony

从buildslave列表中，您可以看到没有mingw32 slave，我不确定在不久的将来是否会有。

无论如何，使用SCons和Mingw64，您应该有一种直接的方式来运行编译过程。只需确保安装了Mingw64和Python 2.6或Python 2.7。然后查看搅拌机来源和lib/mingw64。在Blender源根目录中使用C:\Python27\python.exe scons\scons.py启动编译过程。这应该是开箱即用的。
