我尝试在运行 cmake 之后运行 make 来安装 molsketch，此时我收到输出：

答案1
杜宁制作，我在48%的时候遇到了和你一样的问题，
你需要把
Molsketch-0.2.0-Source/libmolsketch/src/stereocenteritem.cpp改一下第 66 行如：std::vector<OpenBabel::OBStereoUnit> units = FindStereogenicUnits(obmol, symmetry_classes);
当编译到90%的时候，遇到另一个问题：
Molsketch-0.2.0-Source/molsketch/src/mainwindow.cpp:22:28：致命错误：QAssistantClient：没有此文件或目录
我的Qt版本是4.8.5。Qt在4.7+之后删除了QAssistantClient。我的解决方案是，注释掉mainwindow.cpp和mainwindow.h中与QAssistantClient相关的每一行。
