Problem installing VLC - clean macports

[onaforeignshore@…]

I am trying to install VLC, but I am running into errors... See ticket #45822 (summary below).

VLC +dbus+full+jack+qtkit+quartz+shout+smb+svg

Error: Requested variants "+quartz" do not match those the build was started with: "+x11".
Error: Please use the same variants again, or run 'port clean gtk2' first to remove the existing partially completed build.
Error: Failed to install gtk2

After installing gtk2 +x11 and restarting VLC install:

--->  Fetching archive for py27-pygtk
Error: org.macports.archivefetch for port py27-pygtk returned: gtk2 must be installed with +quartz.
Error: Failed to install py27-pygtk

At this point I cleared the MacPorts out again and restarted with: port install VLC +dbus+full+jack+qtkit+quartz+shout+smb+svg+x11

--->  Computing dependencies for VLCError: librsvg: Variant x11 conflicts with quartz
Error: Unable to execute port: Error evaluating variants

I will be willing to help fix the issue if required

From the other ticket:

proliferation of +quartz to ports that don't properly support it (and work if they have been installed previously with the default +x11, but not when you install a dependent port with that option).

It's probably more subtle than that. I'm pretty certain those dependencies do support +quartz or +x11 properly, but many will not support both at the same time. I have never tried to install all my GTk(2) ports in +quartz mode but I would presume (hope) that they all either support +quartz (instead of +x11) or else raise an explicit error if that's not the case. There may also be a VLC dependency A that also depend on one of VLC's other dependencies (B), but require +x11 even if VLC itself doesn't use anything x11-related in A. Avahi would be an example of that (see below).

Your first error probably holds part of the clue to what is going wrong here:

Error: Requested variants "+quartz" do not match those the build was started with: "+x11".

Supposing you indeed started from scratch, this means that an attempt was made to install GTk2 before, apparently as a result of installing something that does not have a +quartz variant (I *think* that variants stop propagating when a port is requested that doesn't have the variants in question). For some reason this GTk2 install failed, otherwise you would not get a message about a build that "was started with".

AFAICS, GTk2 and py27-pygtk are pulled in as dependencies of libglade2 which is needed because of VLC dependency avahi . Avahi has x11 as a default port, though that gets unset if +quartz is requested. So that doesn't explain who might have tried to install GTk2 +x11.

I did a sudo port clean all and then a sudo port -f uninstall installed. Next I did sudo port install bash and now I am running sudo port -vd install VLC +qtkit+quartz >& install-VLC.log. Will post the log if it fails, otherwise I will clean it again and start adding variants until it fails

Build failed... have attached the log file

That looks like an error in port:gtk2, possibly because the +quartz variant doesn't install certain files which are expected to be present in the destroot but more probably because a post-destroot block omits a ${destroot} variable somewhere.

Another thing: I should have asked you to post the output of

sudo port -vy install VLC

first. Not that it shows variant propagation reliably, but it would have given a more succinct overview of the order in which dependencies get pulled in.

VLC +qtkit+quartz log file

[onaforeignshore@…]

I replaced the log file with the

sudo port -vy install VLC +qtkit+quartz

version for you

Replying to rjvbertin@…:

That looks like an error in port:gtk2, possibly because the +quartz variant doesn't install certain files which are expected to be present in the destroot but more probably because a post-destroot block omits a ${destroot} variable somewhere.

It seems extremely unlikely to me that a missing ${destroot} would have gone unnoticed so long. I'm not sure what led you to this conclusion. Certainly not the portion of the main.log file quoted above, which contains no relevant information; the real error is earlier.
