When compiling my c++ sources with the -pg option to inject gprof profile instrumentation code the compile fails with the undefined reference to _mcount error.
当用-pg选项编译我的c++源时，可以使用未定义的对_mcount错误的引用来注入gprof配置文件检测代码。
Without this option everything compiles (and runs) fine. What is wrong in my case? (Solaris 10 SPARC Platform)
没有这个选项，一切都可以编译(和运行)。我的情况到底是怎么了?(Solaris 10 SPARC平台)

Are you both compiling each object file and linking the final executable using the '-pg' flag?
您是否在编译每个对象文件并使用“-pg”标志链接最终的可执行文件?
