VTune 探查器给出错误："The Data Cannot be displayed,there is no viewpoint available for data "
VTune Profiler giving Error: "The Data Cannot be displayed,there is no viewpoint available for data "
我想优化我的代码，这是在linux平台上用c++编写的。当我识别热点时，它成功运行我指定路径的二进制可执行文件，然后它给出错误:"数据无法显示，没有可用的视点数据"。
谁能帮我整理一下这个错误?
我刚刚解决了同样的问题，希望对你来说还不算太晚。
首先，您应该启用调试信息，即使用-g选项编译:
icpc -g -o output source.cpp
或
gcc -g -o output source.cpp
如果你喜欢GNU编译器
另一个步骤(重要的)在这里被发现:它说至少在Ubuntu中你必须输入:
echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
这个操作帮助了我，我希望它能帮助你和其他面对这个问题的人在未来。
