所需工具:
过程:
- 编译/安装 pvtrace(make,make install 即可)
 - 将 pvtrace 中instrument.c 拷贝到要进行编译的路径
 - 按如下代码编译测试程序(注意第三行-finstrument-functions 是连起来的):
 
 1: $ ls
 2: instrument.c    test.c
 3: $ $ gcc -g -finstrument-functions test.c instrument.c -o test
 4: $ ./test
 5: $ ls
 6: instrument.c     test.c
 7: test             trace.txt
 8: $ pvtrace test
 9: $ ls
 10: graph.dot        test           trace.txt
 11: instrument.c     test.c
 12: $ dot -Tjpg graph.dot -o graph.jpg
 13: $ ls
 14: graph.dot        instrument.c   test.c
 15: graph.jpg        test           trace.txt
 16: $
我的源码:
1: #include <stdlib.h>
 2:
 3: void step1(){
 4: printf(“I am step1 !\n”);
 5: }
 6:
 7: void step(){
 8: printf(“I am last step !\n”);
 9: }
 10:
 11: void step2(){
 12: printf(“I am step2 !\n”);
 13: step();
 14: }
 15:
16: int main(void){
 17: step1();
 18: step2();
19: return 1;
 20: }

PS:在makefile 中添加中间件编译参考[2]。
