关于如何编译freetype的问题

zlulu2006

这段时间一直在为OSG中的文字显示问题纠结，一是不能加载字体，二是不能显示汉字。关于这两个问题，我在网上寻找到的答案是，没有编译字体插件，即freetype库。
我在freetype官网上下载了一个压缩包，里面对应的文件如下图所示


如果是直接运行文件夹里面的vms_make这个DOS程序，但是运行后很长时间也没什么反应。
如果要用CMake来编译，但是文件夹里面并没有CMakeLists文件
现在不知道该怎么弄了，OSG字体的问题，希望能得到帮助和解答，谢谢！

你用cmake编译osg时，只要你关联了3Dparty这个第三方库，你编译出来的源码就会有FreeType，然后生成一下就可以用了

还是没有发现freetype，运行文字显示的例子，依旧提示找不到插件
不知道是哪里有问题~

array

因为您没有在cmake里面设置freetype相关的头文件路径和依赖库位置

回复 4# array


    您好，谢谢！
我这次设置好了CMake中的相关的路径，如下：

打开那个.sln文件，已经有了Plugins freetype这个编译项，但是编译不通过，输出以下信息：
1>正在链接...
1>FreeTypeFont3D.obj : error LNK2019: 无法解析的外部符号 _FT_Outline_Get_BBox，该符号在函数 "protected: void __thiscall FreeTypeFont3D::init(void)" (?init@FreeTypeFont3D@@IAEXXZ) 中被引用

1>生成日志保存在“file://d:\OSG\OpenSceneGraph-2.8.3\src\osgPlugins\freetype\osgdb_freetype.dir\Debug\BuildLog.htm”


是不是我的3rdParty文件有问题？还是我的路径设置不正确？或者还需要其它什么相关的文件呢？

219这个版本太低了，请使用至少235以上的版本

顶下，刚按照这种方法解决了同样的问题

the_mercury

我送你两个osg的freetype插件吧，osgdb_freetyped.dll是debug版本，osgdb_freetype.dll是Release版本，你把它们下载下来之后，对你的计算机上的osg插件目录下面的freetype插件进行替换就行了，这两个插件使用的freetype是2.4.8版本的，对freetype采用的是静态链接，使用的编译环境是Visual C++ 2005。如果插件在你的计算机上不能正常运行的话，请告诉我。

您没指定FreeType依赖库路径吧

licheng

设置好了依赖库路径，原来是源文件里包涵头文件的路径设置有问题。
比如

我的解决办法是把第三方库里的freetype文件夹整个复制出来，然后粘贴到freetype里作为它的子文件夹，这样编译时就能找的到路径了
