linking libjvm.so failed because "cmsLockVerifier.o: file not recognized: File truncated"

[Jovi Zhang]

Hi,
    When I link libjvm.so, it report "cmsLockVerifier.o: file not
recognized: File truncated".

    So I checked the object file, then I found below:

[root at localhost fastdebug]# pwd
/root/Hotspot/hotspot/build/linux/linux_i486_compiler1/fastdebug

[root at localhost fastdebug]# file *|grep empty
cmsLockVerifier.o:                empty
cmsPermGen.o:                   empty

[root at localhost fastdebug]# gcc --version
gcc (GCC) 4.4.2 20091027 (Red Hat 4.4.2-7)

[root at localhost fastdebug]# uname -a
Linux localhost.localdomain 3.1.0-rc2+ #1 SMP Fri Aug 12 08:43:42 CST
2011 i686 i686 i386 GNU/Linux

    Obviously, cmsLockVerifier.cpp compiled successful, but I don't
know why its content is empty.
    Is anybody also encounter this problem?

    The code is lastest hotspot code download from openjdk website,
and I use command "make ALT_BOOTDIR=/usr/lib/jvm/java-1.6.0-openjdk"
