1. srs配置时，指定 --with-pg 0. 若需要图形化，编译dot：
cd 3rdparty/gprof && bash build_gprof2dot.sh
1. srs配置时:
./configure --with-pg
脚本会加入编译参数"-pg -lc_p"，gcc -g -pg -lc_p -c xxx -o xxx.o，即在configure中打开 Performance="-pg -lc_p" 脚本会加入编译参数"-pg -lc_p"，gcc -g -pg -lc_p -c xxx -o xxx.o，即在configure中打开 Performance="-pg -lc_p"

其实gprof生成的日志就可以看，不一定要图形化。 其实gprof生成的日志就可以看，不一定要图形化。
