[GitHub] [incubator-brpc] GOGOYAO opened a new issue #1244: cpu pfofiler 开启失败
GOGOYAO opened a new issue #1244:
URL: https://github.com/apache/incubator-brpc/issues/1244
**Describe the bug (描述bug)**
按照文档编译了brpc，然后在工程中，连接了/usr/lib64/libtcmalloc_and_profiler.so（通过yum安装的gperfs）
最终还是出现
**To Reproduce (复现方法)**
编译brpc时，cmake .. -DBRPC_ENABLE_CPU_PROFILER=ON
编译工程时，除了连接brpc，还链接了/usr/lib64/libtcmalloc_and_profiler.so（通过yum安装的gperfs）
**Expected behavior (期望行为)**
正常开启cpu profiler
**Versions (各种版本)**
OS: centos 7
Compiler: gcc 8
brpc: 11da9c8cbdc2ec8c0da728aedb4ed906717d6e0f
protobuf: 3.11

1. 编译brpc时，带不带-DBRPC_ENABLE_CPU_PROFILER=ON这个都可以
2. 编译工程时，必需要带上-DBRPC_ENABLE_CPU_PROFILER=ON并且链接libtcmalloc_and_profiler.so
因为brpc的profile功能是在.h文件中定义的，只有在链接的时候才会去看BRPC_ENABLE_CPU_PROFILER是否开启，具体代码请看` brpc/details/profiler_linker.h`

是你这样弄的。
我的问题是，”发现cpu profile结果的下拉列表里面，可以正常打开看到cpu profile结果“，但是如果是选择new profile提示的是未开启。很奇怪。
红框里面的都是可以看到profile结果的
