Question

我正在尝试编译使用Qt5的PhantomJS 2。我遇到了这个失败：

我已经安装了freetype2：

$ find / -name ftheader.h
/usr/include/freetype2/freetype/config/ftheader.h
/app/phantomjs/src/qt/qtbase/src/3rdparty/freetype/include/freetype/config/ftheader.h

不知道如何解决这个问题，因为我没有太多的C / C ++构建经验。我可能需要添加/更改前缀，但我不确定如何。

如果查看错误（）的位置，则会在其上方显示以下注释：

55   /* `<prefix>/include/freetype2' must be in your current inclusion path */                                                                                                                                                               
56 #include <freetype/config/ftheader.h>

不确定为什么构建本身没有解决这个问题，因为它解决了它所依赖的其他库，但是在构建配置中添加-I /usr/include/freetype2就可以了。

对于PhantomJS的具体情况，完整的命令是：

./build.sh --confirm --qt-config '-I /usr/include/freetype2'
