Error compiling virt-mem-2.8

Hi all,

I am using FC9 x86_64 and trying to install virt-mem-0.2.8, But i get 
below error when trying to do "make"

Sorry, only just seen this email.

These errors are always caused because the .depend file hasn't been
rebuilt.  Just doing 'make depend' should fix it.  It's probably a bug
in the .depend file we distribute with the tarball ...

You mean, before i run make , i should type "make depend" and then run 
"make" and "make install" ?

Yes, exactly.

You might also want to try out version 0.3.0 which I (quietly)
put out yesterday.

I'm currently rewriting the parsing code again so it can load all
kernel structures automatically -- this turned out to be necessary for
virt-ifconfig because things like the network interface addresses are
stored in multiple, indirect, linked lists of structures/
sub-structures/ sub-sub-..., and writing code to navigate through
those manually was getting very tedious.  Should have something to
show for this by the weekend.

Rich.

I tried this, and i still got the error

I did first ./configure --prefix=/usr/local/virt-mem

then i ran make depend and i got the same error

<snip for virt-mem-0.2.8>

OK, so now you're getting a different error.

This is because you need a newer ocaml-libvirt (try 0.4.4.2).  The one
you have doesn't support the libvirt virDomainMemoryPeek call, which
was only added to libvirt quite recently.

I will add a check into the configure file for that, and also a better
error message.

You have got libvirt installed, right?  If you installed libvirt on
some non-standard path then you may need to tell configure where it
is.  I think you need to do:

  LIBS="/some/nonstandard/path" ./configure

If that doesn't work try LIBRARY_PATH instead of LIBS.

Yes, libvirt is already installed,

[root <at> dhcp7-90 virt-mem-0.3.0]# rpm -q libvirt
libvirt-0.4.4-3.fc10.x86_64
libvirt-0.4.4-3.fc10.i386

which path should i specify as LIBS or LIBRARY_PATH , as the libvirt rpm 
installs libraries of libvirt in /usr/lib64.

You should give /usr/lib64 as the path.

As for why it doesn't work, though, I'm really very confused.
Obviously I don't get the error you're seeing, and I don't understand

Sure ... I'll be building binaries for 0.3.1 on Tuesday, or whenever
the Fedora infrastructure comes back to life.

Re: Error compiling virt-mem-2.8

Here's a build of 0.3.1:

  http://koji.fedoraproject.org/koji/taskinfo?taskID=784664

It failed on ppc64, I think simply because the compiler ran out of
memory compiling one of the biggest source files (kernel.ml which
corresponds to the kernel database).

But it should be OK to use the i686 RPM on 32 bit guests.

You should read the FAQ:
