首先,我正在运行MacOSX 10.7.1.我安装了所有正确的
Xcode 4和所有库,以使用C语言.
原文链接:https://www.f2er.com/bash/383563.html我在shell中运行gprof命令时遇到了麻烦.我将逐步解释我正在做的事情以及我收到的输出.
步骤1:
~ roger$cd Path/to/my/workspace ~ roger$ls
输出(步骤1):
queue.c queue.h testqueue.c
第2步:
~ roger$gcc -c -g -pg queue.c ~ roger$ls
输出(第2步):
queue.c queue.h queue.o testqueue.c
第3步:
~ roger$gcc -o testqueue -g -pg queue.o testqueue.c ~ roger$ls
输出(步骤3):
queue.c queue.h queue.o testqueue testqueue.c
第4步:
~ roger$./testqueue ~ roger$ls
输出(步骤4):
enqueue element 16807 head=0,tail=1 enqueue element 282475249 head=0,tail=2 enqueue element 1622650073 head=0,tail=3 enqueue element 984943658 head=0,tail=4 enqueue element 1144108930 head=0,tail=5 enqueue element 470211272 head=0,tail=6 enqueue element 101027544 head=0,tail=7 enqueue element 1457850878 head=0,tail=8 enqueue element 1458777923 head=0,tail=9 enqueue element 2007237709 head=0,tail=10 queue is full dequeue element 16807 dequeue element 282475249 dequeue element 1622650073 dequeue element 984943658 dequeue element 1144108930 dequeue element 470211272 dequeue element 101027544 dequeue element 1457850878 dequeue element 1458777923 dequeue element 2007237709 queue is empty gmon.out queue.h testqueue queue.c queue.o testqueue.c
第5步:
~ roger$gprof -b testqueue gmon.out > out.txt ~ roger$nano out.txt
输出(步骤5):
