gcc-core requires libvtv0?

gcc-core requires libvtv0?

[Andrew Schulman]

For the last month or so every time I update in setup, in the Resolving
Dependencies pane I see

  libvtv0    ()
             
             Required by: gcc-core

Note the empty version number and description.  I accept it, but the next time I
update, it's back.

Has anyone else seen this?

Andrew

That's another fallout of the gcc-5.2.0 test version, which changed the
dependencies to those for gcc-5.2.0 (that's wrong, IMHO).  It's only
available as "test" as a result, so if you install "curr", then there's no
available version for libvtv that you can install.  I guess we need to
enable different dependencies for "prev", "curr" and "test" in setup.ini.

A simple workaround in this particular case is to just choose libvtv0 for install.

You can't since it's a new library that is not yet available as "curr",
unless you are manually installing the test version.

Yes, that's what I meant---manually install the test version.  It's completely 
harmless to do that, since the library isn't used by the current version of any 
other package.

But someone installing the current gcc will not get the correct
libraries installed unless these get pulled in by other packages (I
believe they are, but I haven't checked), so that's still wrong.  If a
test package has different dependencies than the current one, setup.hint
should have the dependencies for "curr" correct and anyone installing
"test" needs to be aware that there's maybe some dependencies to install
by hand, which the announcement should helpfully provide.

I'm surprised that this hasn't occurred already because of this.  Yes
the dependency tree needs to be needs to be cognizant of version of
dependencies as well as differing libraries.

It likely would have occured already if it was a simple patch to setup.
But it minimally needs changes to cygport, setup.hint, setup.ini and
upset as well, so here we are.

Already happened all the time we have test versions that bump libs.
It is also one of the reason why going "prev" is not always possible.

I agree. It is a really a substantial job and should include
moving from setup.hint to <package>-<version>.hint to correctly manage
all dependencies.

As upset seems a big blob, I doubt we will have voluntaries to add that 
portion. Plus of course we need to modify setup-<arch>.exe to correctly 
manage the new setup.hint.
