[Xen-devel] Hi all,

[Lakshitha Harshan <harshan.dll@xxxxxxxxx>]

I'm trying to write the hash values of shared memory pages to a disk file. To do that i have changed mem_sharing.c code. The change includes a call to fopen function.

However when compiling the source i got the following error. I have included header files which are on "/usr/include".

make -f /home/thilakshi/Xen/Xen-4.2/xen-4.0-testing.hg/xen/Rules.mk /home/thilakshi/Xen/Xen-4.2/xen-4.0-testing.hg/xen/common/symbols-dummy.o

Can someone please check this error and tell me where to correct?

Thanks.

Harshan
