Re: [libvirt] Building on Solaris 11 Express

I tested this patch. I'll discuss that first and then recount the
problems I experienced along the way.

The patch seems to achieve the desired effect. libvirtd starts up as the
user xvm. (That said, with Oracle dropping the xvm feature, I'm not sure
if this is better than just running as root.)

VirtualBox (and VBoxSVC) were crashing with "Memory fault", apparently
because they couldn't create /.VirtualBox (xvm's ~ is /). Once I created
that directory (and chown'ed/chgrp'ed it to xvm), I could start VBoxSVC.
From there, virsh connects. It seems to intermittently have problems;
I'm trying to reproduce that issue before I can go much further.

For this testing, I thought it'd be good to use a git checkout, as we
had previously discussed. I was hung up for a while because the gnulib
git repository was down. Now it seems to be back up, so I'm trying
again. Unfortunately, I'm having a number of build issues:


1) I only have gettext 0.16, so I made these changes:

2) The script isn't finding my automake and aclocal, even though they're
installed. Solaris has those executables named with a version number.
I'm not experienced enough with Solaris to know if there's any standard
way via the package manger to make one available as just plain automake
(similar to Debian's alternatives system). So I just did this:

ACLOCAL=aclocal-1.9 AUTOMAKE=automake-1.9 ./autogen.sh


3) The bootstrap script previously (when I had manually copied in a
gnulib git checkout from a month-or-so-old libvirt checkout on Linux)
was complaining that rpcgen didn't exist. I've never heard of that
program, but I apparently have something by that name installed:

# rpcgen
rpcgen  (1.1)
usage:  rpcgen infile
        rpcgen [-abCLNTMA] [-Dname[=value]] [-i size] [-I [-K seconds]] [-Y path] infile
        rpcgen [-c | -h | -l | -m | -t | -Sc | -Ss | -Sm] [-o outfile] [infile]

-v              print version information and exit
-Y path         path where cpp is found


4) The bootstrap script (well, really autopoint) failed because cvs is
not installed:
./bootstrap: cp ._bootmp/gnulib/lib/glthread/threadlib.c gnulib/lib/glthread/threadlib.c # with edits
./bootstrap: (cd ._bootmp2; autopoint) ...
autopoint: *** cvs program not found
autopoint: *** Stop.
Failed to bootstrap, please investigate.

Why on earth does it want cvs? Is that really used? I installed it so I
could move on.


5) pod2man is not in the PATH on Solaris. This patch detects it:

6) I still had the issue with the version script code. Here's the error
output:

As I mentioned before, this change "fixes" the problem:
         VERSION_SCRIPT_FLAGS=-Wl,--version-script=
         `$LD --help 2>&1 | grep -- --version-script >/dev/null` || \
        -    VERSION_SCRIPT_FLAGS="-Wl,-M -Wl,"
        +    VERSION_SCRIPT_FLAGS=""

The more I look into this, though, the less I think that's correct. But
I don't know enough about symbol versioning, especially under Solaris,
to figure out the correct fix.


=======
BACK ON LINUX:

Since I was having so much trouble building from a git clone of libvirt
on Solaris 11 Express, I decided to do the git checkout on my Linux
machine and run `make dist` there. Unfortunately, make dist failed on
Linux (Ubuntu Natty):
