The file graphKit.o existed but with a size of zero.

When I looked into the compilation of graphKit.cpp, there were no such error, below are the lines taken from build.log (I am new to make and know little about thie env, I hope I am providing the right stuff, and as build.og)

CCACHE_COMPRESS=1  CCACHE_SLOPPINESS=time_macros /usr/bin/ccache /usr/lib/ccache/g++ -DLINUX -D_GNU_SOURCE -DIA32 -DASSERT -DFASTDEBUG -I. -I/disk1/development/jdk/jdk8/jdk8/hotspot/src/share/vm/prims -I/disk1/development/jdk/jdk8/jdk8/hotspot/src/share/vm -I/disk1/development/jdk/jdk8/jdk8/hotspot/src/share/vm/precompiled -I/disk1/development/jdk/jdk8/jdk8/hotspot/src/cpu/x86/vm -I/disk1/development/jdk/jdk8/jdk8/hotspot/src/os_cpu/linux_x86/vm -I/disk1/development/jdk/jdk8/jdk8/hotspot/src/os/linux/vm -I/disk1/development/jdk/jdk8/jdk8/hotspot/src/os/posix/vm -I../generated -DHOTSPOT_RELEASE_VERSION="\"24.0-b07\"" -DHOTSPOT_BUILD_TARGET="\"fastdebug\"" -DHOTSPOT_BUILD_USER="\"mpujari\"" -DHOTSPOT_LIB_ARCH=\"i386\" -DHOTSPOT_VM_DISTRO="\"OpenJDK\"" -DTARGET_OS_FAMILY_linux -DTARGET_ARCH_x86 -DTARGET_ARCH_MODEL_x86_32 -DTARGET_OS_ARCH_linux_x86 -DTARGET_OS_ARCH_MODEL_linux_x86_32 -DTARGET_COMPILER_gcc -DCOMPILER2 -DCOMPILER1 -fPIC -fno-rtti

after the statement above I can not see any errors, every thing looks fine.

I hope the you were talking about the above log.

I deleted graphKit.o and did a rebuild but ended in the same error.

Please direct me if I am missing something.

thanks and regards,

The file appears truncated so something went wrong creating it (or else 
one process was trying to write to it at the same time another process 
was trying to read?)

Can you see where graphKit.cpp was compiled? Was there any error 
indicator at that time?

Can you make the build more verbose so that the actual link command can 
be seen - that would show whether the set of files being linked appears 
correct or not.

If you delete graphKit.o and rebuild does the error disappear?
