[LTP] Failed to build ltp 20101031 on RHEL5u6

[Romu <hu...@gm...>]

Hi all,

I failed to build ltp 20101031 on RHEL5u6 beta (i686):

./configure
make all

gcc -g -O2 -g -O2 -fno-strict-aliasing -pipe -Wall -D_GNU_SOURCE
-I/root/ltp-full-20101031/testcases/realtime/include
-I../../../../include -I../../../../include
-L/root/ltp-full-20101031/testcases/realtime/lib -L../../../../lib
async_handler.c   -lrealtime -lpthread -lrt -lm -o async_handler
/root/ltp-full-20101031/testcases/realtime/lib/librealtime.a(librttest.o):
In function `atomic_add':

make[4]: *** [async_handler] Error 1

make: *** [testcases-all] Error 2

I googled and some people said "-march=i686" should be used.  I tried:

CFLAGS="-march=i686" ./configure
CFLAGS="-march=i686" make all

still got the same error.

Any idea?
