Non-universal build dependencies prevent universal builds

[ryandesign (Ryan Carsten Schmidt)]

MacPorts 1.9.0 beta 1 prevents the installation of the universal variant of some ports that had no trouble installing with the universal variant under MacPorts 1.8.2, specifically those which have build dependencies that can't build universal:

bash-3.2# port install xorg-server +universal
--->  Computing dependencies for xorg-serverWarning: xorg-applewmproto has no universal variant

Error: Cannot install xorg-server for the arch(s) 'i386 x86_64' because

Error: and does not have a universal variant.
Error: Unable to execute port: architecture mismatch
To report a bug, see <http://guide.macports.org/#project.tickets>

I don't think MacPorts needs to be checking that the architectures of build dependencies match the current port's requested architectures. The build dependencies' architectures just need to be compatible with the machine doing the building.

Use depends_skip_archcheck.

How do you use depends_skip_archcheck. I googled "depends_skip_archcheck site:macports.org", but got nothing which indicates how I would use this flag/command, or whatever it is.

Joshua is saying that every port that depends on a port that is not universal, but that does not care about that, should be modified to include the line "depends_skip_archcheck theport" where "theport" is the name of the port whose architectures need not be checked. This is something a port maintainer would be changing; it's not something an end user needs to be concerned with. If you are experiencing this error, you should file a ticket so the maintainer of the applicable port can make the needed change.

I am trying to install wxwidgets through ports, and smpeg is failing, because it will not build universal. Joshua, the ticket has already been opened, and closed (!@#!@%), quite a few times over the last year. When closed, the message is "don't build universal", but I cannot work out how to do this.

To get through my roadblock, I think I need to work out how to add depends_skip_archcheck to the port as an enduser. I am not an expert in ports, or a unix sysadmin, but an AI researcher - so this type of thing is not my specialty. So, is that the correct thing to do? How would I do it?

This ticket was filed 6 months ago by me and closed as invalid 6 months ago by Joshua. We should not be adding more comments to it.

I assume you are referring to the smpeg ticket #26937 so any further comments about that issue should be continued there.
