Thanks for your reply!
After I check the config.log, I think all check go into the right place, but confdefs.h didn't show up, it's sort of weird.
Some output from config.log:
configure:6159: checking libaio.h usability
configure:6159: gcc -c -g -O2  -D_FORTIFY_SOURCE=2 conftest.c >&5
configure:6159: $? = 0
configure:6159: result: yes
configure:6159: checking libaio.h presence
configure:6159: gcc -E  -D_FORTIFY_SOURCE=2 conftest.c
configure:6159: $? = 0
configure:6159: result: yes
configure:6159: checking for libaio.h
configure:6159: result: yes
configure:6170: checking for io_setup in -laio
configure:6195: gcc -o conftest -g -O2  -D_FORTIFY_SOURCE=2  conftest.c -laio   >&5
configure:6195: $? = 0
configure:6204: result: yes
configure:6218: checking io_set_eventfd is defined in aio library or aio header

I'm confused about the reason why I didn't got the confdefs.h. Is this the normal case or just happend to me?
BTW, I tried find . -name confdefs.h  under ltp topdir, it gets nothing.

After you run ./configure, look at config.log to see what *aio checks failed.
