Re: [posixtest-discuss] PTS question about semaphore test

Hi xiaoxiao,
Welcome to posixtestsuite world:-)
For semaphore function testing, did you check whether NPTL is installed =
as default posix thread library at your side?  if so, you can use =
'-lpthread' and '-lrt' flags. Otherwise, to build against NPTL, export =
the following variable:
export GLIBCDIR=3D/path/to/NPTL/libc-build
Then in LDFLAGS, add the following lines:=20
$GLIBCDIR/nptl/libpthread.so.0 $GLIBCDIR/libc.so.6 =
-Wl,-rpath,$GLIBCDIR:$GLIBCDIR/nptl:$GLIBCDIR/elf,-dynamic-linker,$GLIBCD=
IR/elf/ld-linux.so.2
If you want to run the semaphore test suite against posix1b (downloading =
it from: http://www.garret.ru/~knizhnik/posix1b.tar.gz =
<http://www.garret.ru/~knizhnik/posix1b.tar.gz> ), then you should have =
the library compiled and installed in /usr/lib first. It seems you =
already did so. That's fine. Then add the following library in the =
LDFLAGS:=20
                -lposix1b
Make sure /usr/lib/ is in your PATH.
For more info about how to BUILD and run test suite, you can refer to =
BUILD and Document/HOWTO_*** documents within posixtestsuite.=20
If you want to run the whole testsuite, I suggest you logged as root, =
since some build needs root privileges.=20

Any problem, feel free to let me know.

Hi, PTS project admins,

Currently we are trying to use PTS to evaluate our linux kernel upgrade. =
When we test semaphore function under conformance/interfaces. We got one =
issue. If we put -lpthread in LDFLAGS, we got error as "sem_open: =
function not implemented". But if we remove it the linker seems to find =
the posix1b lib that we have built. Also some of the tests seem to =
require root privileges. Is it required that we be logged in as root on =
the system where we run these tests?

Thanks a lot in advance.

Xiaoxiao
