[PATCH 2/2] daemon: Link guestfs_protocol.[ch] into the daemon directory.

by Jim Meyering

I haven't received this yet, but read from the archive: https://www.redhat.com/archives/libguestfs/2009-November/msg00268.html The only suspicious part is the trailing ".c" on the command below: +$(libsrcdir)/guestfs_protocol.c: force + $(MAKE) -C $(libsrcdir) guestfs_protocol.c +$(libsrcdir)/guestfs_protocol.h: force + $(MAKE) -C $(libsrcdir) guestfs_protocol.c Shouldn't that be .h?

Notes: Building the daemon on Windows

by Richard W.M. Jones

My aim is to get to the stage where we can start the daemon and run it under Wine. By using a dummy QEMU wrapper[1] we can have the daemon be run from a real Linux libguestfs program. It'll be running on the same machine (not in an appliance) and it'll be running under Wine, not Windows, but that's good enough to start testing the XDR protocol and some simple commands. It's very close to being able to do that now - there are only a few minor fixes left. If you want to try this, you will need the latest libguestfs sources from git, plus the three attached patches which hack out bits that I've not fixed yet. You'll need the basic Fedora MinGW cross-compiler packages installed, and the Fedora package "wine(x86-32)". You'll need to build and install PortableXDR: http://git.annexia.org/?p=fedora-mingw.git;a=tree;f=portablexdr;hb=HEAD Configure the toplevel of libguestfs source as if you were going to build it for Fedora. The go into the daemon subdirectory and reconfigure it for cross-compilation: cd daemon make distclean mingw32-configure make That will get you 99% of the way there. There are still some bits to hack out and/or fix in order to get a daemon. Rich.

Building guestfs_protocol.o in the daemon

by Richard W.M. Jones

Recently we changed the daemon so it builds guestfs_protocol.o by this rule: $(libsrcdir)/guestfs_protocol.o: force $(MAKE) -C $(libsrcdir) guestfs_protocol.o guestfsd_LDADD = \ $(libsrcdir)/guestfs_protocol.o \ #... The problem with doing this when building on Windows is that the toplevel src/ directory will be configured differently from the daemon/ directory. This means that the above rule compiles guestfs_protocol.o as a Linux object file, which obviously can't be linked to the Win32 daemon. [The exact error is attached at the end] We only configure the daemon/ directory for cross-compiling, partly because the daemon is supposed to be a separate entity, mainly because it'd be a huge amount of work to make the toplevel configure.ac into something which is Win32-friendly. I'm not sure what a good way to solve this is though. My thoughts: (a) Copy guestfs_protocol.[ch] into the daemon and treat it totally separately. (b) Revert the change so we're building again with a rule like: guestfsd_SOURCES = ../src/guestfs_protocol.c \ ../src/guestfs_protocol.h \ #... I think the change was made originally to support parallel makes, so I don't know if doing this will break parallel makes again. (c) Something else ...? Is there a way to tell automake to put the object file into the local directory so that we can use the rule above but not have it break parallel make? I think I prefer plan (a) ...
