OpenTransactions/Protobuf 模棱两可的错误

Question

我正在尝试编译 OpenTransactions，但我必须先安装一些其他项目，编译器在某个点停止并向我显示此错误日志：

我先运行进入并解决了它（我认为）。有人对此有任何见解吗？

这个问题可能与编译器有关，但我的 (gcc 4.9) 确实卡在了这一点，因为它不知道要调用哪个构造函数，所以应该做的是将 int64 转换为参数两行（OTData 开始和 OTData 在 src/client/OpenTransactions.cpp 中的第 4514 和 4515 行结束）感谢 Chris Odom 在 push.

中的帮助，此问题今天已得到修复
