I'm used to gprof for profiling my C code, but I want to start using a GUI-based Windows application such as Luke Stackwalker. gprof works perfectly fine on my binary, but Luke Stackwalker has some issues:
我习惯了gprof来分析我的C代码，但是我想开始使用基于gui的Windows应用程序，比如Luke Stackwalker。gprof对我的二进制文件做得很好，但是Luke Stackwalker有一些问题:
Launching executable C:\lshare\POT03\Eclipse\Debug\POTaak3.exe.

ERROR: SymGetModuleInfo64, GetLastError: 1114 (Address: 7C90E514)
Sorting profile data.
Done; 2 samples collected at 1.$ samples/second.
Who shot the who in the what now? What am I doing wrong here? I did remember to use the -pg flag.
谁在什么地方开枪了?我在这里做错了什么?我记得使用-pg标志。

I understand why you want something other than gprof. Luke Stackwalker takes stack samples, but (last time I checked) it doesn't summarize inclusive % of wall-clock time used at the level of lines of code. On Linux, you could use lsstack or pstack, and there must be a similar tool on Windows. In your situation, I just rely on the pause button in the IDE to take stackshots.
我理解你为什么想要除gprof以外的东西。Luke Stackwalker接受了堆栈样本，但是(上次我检查过)它没有总结在代码行级别上使用的壁挂式时钟时间的包含百分比。在Linux上，您可以使用lsstack或pstack, Windows上必须有一个类似的工具。在您的情况下，我只是依赖IDE中的pause按钮进行堆栈快照。

The SymType -unknown- means that either the program has not been compiled with the gcc -g option to generate debug info, or the debug info format cannot be recognized by the microsoft debughelp library that is used by Luke Stackwalker.
符号类型-未知-意味着程序没有使用gcc -g选项编译来生成调试信息，或者调试信息格式不能被Luke Stackwalker使用的microsoft debughelp库识别。
Please check that you are using the -g option when compiling the program (and not stripping the executable). Otherwise, it would be nice to know which gcc version you are using.
请检查您在编译程序时是否使用了-g选项(并没有剥离可执行文件)。否则，最好知道您正在使用哪个gcc版本。
