[LTP] Build error of "regress.c"

["Mitani" <mitani@ryobi.co.jp>]

Hi,

I ran "make" with "ltp-2009-12-16" and "ltp-2009-12-18" cvs, 
but it failed:
------------

------------

"regress.c" was not compiled before "ltp-2009-12-15" cvs.
It seems to have been compiled after "ltp-2009-12-16" cvs 
for the first time.


The results of "make" are various by environment as follows:

  (1) RHEL5.4(2.6.18-164.el5) x86    : succeeded
  (2) RHEL5.4(2.6.18-164.el5) x86_64 : failed
  (3) RHEL5.4(2.6.18-164.el5) ia64   : failed
  (4) RHEL4.8(2.6.9-89.ELsmp) x86    : succeeded

There is "/usr/local/include/event.h" file in the successful system.
There is not "/usr/local/include/event.h" file in the failed system.

"/usr/local/include/event.h" file completely accords with 
"${LTPROOT}/testcases/kernel/syscalls/libevent/event.h" file.
I think that "${LTPROOT}/testcases/kernel/syscalls/libevent/event.h"
copied to "/usr/local/include/event.h" when installed.

However, depending on system, there seems to be the case that 
this file isn't copied.


---

Instead of "/usr/local/include/event.h", I installed "libevent-devel"
(libevent-devel-1.1a-3.2.1.x86_64.rpm) to above (2) system.
Then "/usr/include/event.h" file was installed.
This "/usr/include/event.h" file does not completely accord with
"/usr/local/include/event.h".
But after that, "make" succeeded.

I don't think that this measure is right. This is the wrong way, I think.
Because, I judge that LTP is going to copy a "/usr/local/include/event.h"
file by oneself.



Thank you--
