我想獲得代碼覆蓋率信息。在運行時只有一個功能。例如,我只想知道哪些行「run()」已經通過。C++代碼覆蓋期間運行只有一個功能
TEST.CPP:
#include "..."
int main(){
init();
gcov_start_recording();
run();
gcov_end_recording();
return 0;
}

It is unable to get source code information from a normal binary file. My basic idea is : 1. Executable should be complied as debug version , which keep the symbol infomation. 2. You need a external wrapper script for GDB. set break point at entry and exit of the function. collect trace output from GDB . filter the duplicate line in the output . finally you will get the code cover information .
你怎麼樣谷歌「的gcov」和閱讀教程,然後回來,如果你不能得到的指示工作。 – 2013-05-09 12:58:16
