Hello list,
I don't know if I should file a bug so I'm asking here: I got problems building libvirt with obsolete headers from glibc + libtirpc headers.
Which versions of glibc and libtirpc?
I met the "'xdr_u_int64_t' undeclared" error as it seems XDR_CFLAGS are never taken into account, no matter I "export" them, tweaks CFLAGS or add -I/usr/include/tirpc flags.
Building on x86_64, libvirt 1.0.4 and 1.0.5 have the same behaviour here.
Header is present:
$ grep xdr_u_int64_t $(find /usr/include) 2>/dev/null /usr/include/tirpc/rpc/xdr.h:extern bool_t xdr_u_int64_t(XDR *, u_int64_t *);
Here is the log. Please notice the empty "xdr:" line in the configure's summary :
--- + CFLAGS='-O2 -fPIC -pipe' + CXXFLAGS='-O2 -fPIC -pipe' + LDFLAGS=-I/usr/include/tirpc + ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --libdir=/usr/lib64 --libexecdir=/usr/lib64/libvirt --mandir=/usr/man --infodir=/usr/info --docdir=/usr/doc/libvirt-1.0.5 --with-init-script=systemd --with-interface --with-storage-lvm --with-udev --build=x86_64-0-linux-gnu
x86_64-0-linux-gnu is an unusual target triple.

If I can figure out how to reproduce this, I'd probably be in better shape to help fix it. Is there ANY 64-bit xdr_ conversion function in the rpc setup your system has, or are we going to have to break down and write our own on systems that lack a native 64-bit support? -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
