如何在一个工程里加入行号信息

rookieug

现在因为需要，我和一同学，我俩开始看gzip的源代码

我直接./configure
make
之后，想gdb调试一下
设置断点
然后想单步执行，但由于编译的时候，没有加入行号信息，所以单步执行不了
我想请教下，如何在现有情况下加入行号信息呢？
我手动更改Makefile吗？
望高手指教，谢谢





源代码可以在http://www.gzip.org/上下载。

./configure生成的Makefile如下

该如何加入呢？？？

prolj

不明白，gdb 里面用 list 命令不是可以看到行号么？

gawk

CFLAGS="-O -DOS2"
这个改一下，加上-g看看

langue

加上 -g3！

cugb_cat

去掉-O2，加上-g
