Which of these apply, if any? [linux]

You appear to have ELF support. I'll try to use it for dynamic loading.
If dynamic loading doesn't work, read hints/linux.sh for further information.
Operating system name? [linux]
Operating system version? [4.8.0-49-generic]
Installation prefix to use? (~name ok) [/usr]
AFS does not seem to be running...
What installation prefix should I use for installing files? (~name ok)
[/usr]
Getting the current patchlevel...
Build a threading Perl? [y]
Use which C compiler? [cc]

What is the file extension used for shared libraries? [so]

Checking for optional libraries...
What libraries to use?
[-lpthread -lnsl -lgdbm -ldl -lm -lcrypt -lutil -lc -lgdbm_compat]
What optimizer/debugger flag should be used? [-O2]
Any additional cc flags?
[-D_REENTRANT -D_GNU_SOURCE -fwrapv -fno-strict-aliasing -pipe -fstack-protector-strong -I/usr/local/include]
Let me guess what the preprocessor flags are...
Any additional ld flags (NOT including libraries)?
[ -fstack-protector-strong -L/usr/local/lib]
Checking your choice of C compiler and flags for coherency...
I've tried to compile and run the following simple program:

#include <stdio.h>
int main() { printf("Ok\n"); return(0); }

I used the command:

cc -o try -O2 -D_REENTRANT -D_GNU_SOURCE -fwrapv -fno-strict-aliasing -pipe -fstack-protector-strong -I/usr/local/include -fstack-protector-strong -L/usr/local/lib try.c -lpthread -lnsl -lgdbm -ldl -lm -lcrypt -lutil -lc -lgdbm_compat
./try

and I got the following output:

./try: error while loading shared libraries: libgdbm.so.4: cannot open shared object file: No such file or directory
The program compiled OK, but exited with status 127.
You have a problem. Shall I abort Configure [y]
Ok. Stopping Configure.

why libgdbm.so.4 can not open, I have installed the gdbm1.13.

Have you checked that the libraries are actually in place? It's easy when doing a build to forget the make install step. I've done that on occasion. What's the output of ls -l libgdbm.so*?

By the way, the book recommends GDBM-1.12.

Now that you've received a reply, XinyuLi, can I point out that we are all volunteers here on LQ so using the word "URGENT" in your thread title not only will have no effect but comes over as slightly rude.

Also, please enclose any code or output in CODE tags (use the # button on the advanced toolbar) to make it more readable.

Many thanks, welcome to LQ, and I hope you resolve your problem.

As above about code tags, but I did notice that you have chosen to add an additional switch (-Dusethreads n), so as you have deviated from the book it really is your choice and so are the unforseen side effects. So along with using a different version of gdbm than the recommended, my suggestion would be go back and follow the instructions until you are sure you are in a position to make changes as you see fit
due to your knowledge of what can and cannot be successfully altered.
