c++ - 在分析由ARM设备创建的文件时，gperftools cpuProfiler无法看到simbols

我想分析一个在ARM设备中运行的C ++应用程序。我运行了我的应用程序并使用ProfilerStart（＆＃34; googleProfBL.prof＆＃34;）对其进行了分析，因此生成了该文件。当我从本地计算机中的ARM设备打开文件时，我得到：



./pprof --text --add_lib=libraryIwanttoDebug.so BinaryThatLoadsThatLibrary googleProfBL.prof 
Using local file /home/genius/PresControler/src-build-target/deploy/NavStartup.
Using local file ../traces/googleProfBL.prof.
Warning: address ffffffffffffffff is longer than address length 8

    144   2.7%   7.5%      144   2.7% 0x76da2cc4
    126   2.4%   9.9%      126   2.4% 0x5d0f8284
    114   2.1%  12.0%      114   2.1% 0x76d27386
     64   1.2%  13.2%       64   1.2% 0x76dba2dc
     53   1.0%  14.2%       53   1.0% 0x76dba1f4
      ...

so库是在调试模式下编译的（没有剥离），我不知道为什么我没有得到这些符号。

我试过了：

./pprof --text --add_lib=aFileOfTheLibrary.o BinaryThatLoadsThatLibrary googleProfBL.prof Looks like I got a couple of symbols.
