[LTP] About POSIX "sched_yield/1-1.c" buld failure

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

Hi,

I reported that build failure of POSIX test set "conformance/interfaces/
sched_yield/1-1" was still left in RHEL4.8 system:

http://www.mail-archive.com/ltp-list@lists.sourceforge.net/msg10713.html

In addition, build of the following tests failed by the reason of 
"undefined reference":
------------
conformance/interfaces/pthread_barrierattr_getpshared/1-1
conformance/interfaces/pthread_barrierattr_getpshared/2-1
conformance/interfaces/pthread_barrierattr_init/1-1
conformance/interfaces/pthread_barrierattr_setpshared/1-1
conformance/interfaces/pthread_cond_broadcast/1-2
conformance/interfaces/pthread_cond_broadcast/2-3

conformance/interfaces/pthread_cond_timedwait/2-7
conformance/interfaces/pthread_cond_timedwait/4-2
conformance/interfaces/pthread_cond_wait/2-2

conformance/interfaces/pthread_condattr_getclock/1-1
conformance/interfaces/pthread_condattr_getclock/1-2
conformance/interfaces/pthread_condattr_setclock/1-1
conformance/interfaces/pthread_condattr_setclock/1-2
conformance/interfaces/pthread_condattr_setclock/1-3
conformance/interfaces/pthread_condattr_setclock/2-1
conformance/interfaces/pthread_getschedparam/1-3
conformance/interfaces/pthread_mutex_getprioceiling/1-1
conformance/interfaces/pthread_mutexattr_getprioceiling/1-1
conformance/interfaces/pthread_mutexattr_getprioceiling/1-2
conformance/interfaces/pthread_mutexattr_getprioceiling/3-1
conformance/interfaces/pthread_mutexattr_getprotocol/1-1
conformance/interfaces/pthread_mutexattr_getprotocol/1-2
conformance/interfaces/pthread_mutexattr_setprioceiling/1-1
conformance/interfaces/pthread_mutexattr_setprioceiling/3-1
conformance/interfaces/pthread_mutexattr_setprioceiling/3-2
conformance/interfaces/pthread_mutexattr_setprotocol/1-1
conformance/interfaces/pthread_mutexattr_setprotocol/3-1
conformance/interfaces/pthread_mutexattr_setprotocol/3-2
conformance/interfaces/pthread_setschedprio/1-1
conformance/interfaces/sched_yield/1-1
------------

The environment is as follows:
  - RHEL4.8 --- (x86, x86_64, ia64)
  - kernel  --- kernel-2.6.9-89.EL
  - glibc   --- glibc-2.3.4-2.43


But I found out a method of avoidance of some of these failures.
And I succeeded to build "conformance/interfaces/sched_yield/1-1".



For example, the log of "conformance/interfaces/
pthread_barrierattr_getpshared/1-1" is as follows:
------------
conformance/interfaces/pthread_barrierattr_getpshared/1-1 compile FAILED;
SKIPPING
/tmp/cc8gB5Qj.o(.text+0x3e): In function `main':
: undefined reference to `pthread_barrierattr_getpshared'
collect2: ld returned 1 exit status
------------

I extracted insufficient functions from these logs:
------------
pthread_barrierattr_getpshared
pthread_condattr_getclock
pthread_condattr_setcloc
pthread_condattr_setclock
pthread_mutex_getprioceiling
pthread_mutexattr_getprioceiling
pthread_mutexattr_getprotocol
pthread_mutexattr_setprioceiling
pthread_mutexattr_setprotocol
pthread_setaffinity_np
pthread_setschedprio
------------

In RHEL3.x/RHEL4.x systems, some of these functions were included in 
nptl-devel package.

I did the followings:
  1. Installed nptl-devel package.

  2. Exported LIBRARY_PATH:
       export LIBRARY_PATH=/usr/lib/nptl
       export LIBRARY_PATH=/usr/lib64/nptl       ---(in x86_64)

  3. Added "-lpthread" to "conformance/interfaces/lio_listio/LDLIBS" file.


Is the method mentioned above right?

postscript:

Now, build of the following tests failed even if I took the method 
mentioned above:
------------
conformance/interfaces/pthread_mutex_getprioceiling/1-1
conformance/interfaces/pthread_mutexattr_getprioceiling/1-1
conformance/interfaces/pthread_mutexattr_getprioceiling/1-2
conformance/interfaces/pthread_mutexattr_getprioceiling/3-1
conformance/interfaces/pthread_mutexattr_getprotocol/1-1
conformance/interfaces/pthread_mutexattr_getprotocol/1-2
conformance/interfaces/pthread_mutexattr_setprioceiling/1-1
conformance/interfaces/pthread_mutexattr_setprioceiling/3-1
conformance/interfaces/pthread_mutexattr_setprioceiling/3-2
conformance/interfaces/pthread_mutexattr_setprotocol/1-1
conformance/interfaces/pthread_mutexattr_setprotocol/3-1
conformance/interfaces/pthread_mutexattr_setprotocol/3-2
------------

The insufficient functions are as follows:
------------
pthread_mutex_getprioceiling
pthread_mutexattr_getprotocol
pthread_mutexattr_getprioceiling
pthread_mutexattr_setprioceiling
------------

The man-page of these functions exist, but the definitions don't exist 
in header files.
------------
[root@RHEL48-LTP-EM64T ~]# grep -r pthread_mutex_getprioceiling /usr/include
[root@RHEL48-LTP-EM64T ~]# grep -r pthread_mutexattr_getprotocol
/usr/include
[root@RHEL48-LTP-EM64T ~]# grep -r pthread_mutexattr_getprioceiling
/usr/include
[root@RHEL48-LTP-EM64T ~]# grep -r pthread_mutexattr_setprioceiling
/usr/include
[root@RHEL48-LTP-EM64T ~]# 
------------

And there aren't these functions in libraries.
------------
[root@RHEL48-LTP-EM64T ~]# nm /usr/lib/*.a | grep pthread_mutex
nm: vsnprintf_nonpic.o: no symbols
nm: mt_support.o: no symbols
nm: snprintf.o: no symbols
[...]
nm: strtol.o: no symbols
nm: strtoul.o: no symbols

[root@RHEL48-LTP-EM64T ~]# nm /usr/lib64/*.a | grep

pthread_mutex_getprioceiling
nm: old_atexit.o: no symbols

nm: strtoull.o: no symbols
[...]
nm: ptw-pwrite64.o: no symbols
nm: pthread_kill_other_threads.o: no symbols
nm: shm_unlink.o: no symbols
------------

I think that I have to investigate about these a little more.
