Hi, Fedora-Legal,

Congratulations on FC12 ! Can't wait to try it out.

Here's my question:

How does the package system (e.g. apt/up2date/yum???) deal with dependencies that can be satisfied by more than 1 package? Or does this just not matter in real life?

I put together a list of all pertinent "Provides" entries on the FC11 i386 DVD that can be satisfied in more than one way. The list is pretty small (25 entries) since I discarded things that never show up in "Requires". Any tips on how I should choose which package to depend on for what I'm doing (analyzing licensing between a package and its dependencies).

Ambiguous maintainer "provides": ------------------------------------- dbus-bluez-pin-helper java java-sasl jaxp_parser_impl jaxp_transform_impl jce jre jsp jsse kdelibs kernel kernel-devel kernel-drm-nouveau libproxy-pac pcsc-ifd-handler pinentry-gui policykit-authentication-agent qt servlet syslog text-www-browser

Ambiguous AutoReqProv "provides:" ------------------------------------- libbaconvideowidget.so.0 libjawt.so libjvm.so libxpcom.so

Here's a specific example for "Provides: jaxp_transform_impl":

saxon Java XSLT processor saxon-6.5.5-2.3.fc11.src.rpm http://saxon.sourceforge.net/ mplv1.0

xalan-j2 xalan-j2-2.7.0-8.5.fc11.src.rpm http://xalan.apache.org/ asl 1.1 and asl 2.0 and w3c

yours,

Julius

I was looking at the some of the dependencies generated by AutoReqProv in the RPMS in Fedora 11 and I noticed the following:

eclipse-swt (epl) requires: libxpcom.so provided-by: nspluginwrapper (gplv2+)

This is actually linked to xulrunner, which is "MPLv1.1 or GPLv2+ or LGPLv2+".

Thanks so much for this clarification!  I see now where I made a mistake.  Oops.

Hi, Spot,

Thanks for the note! I don't yet know how to "look at what packages were used in the buildroot," but I'll try to figure that out.

Meanwhile here's my best guess at resolving these:

We really should clean these up. While it is possible to have multiple packages provide the same component, in practice, it should be treated as a conflict.

For your testing, I would look at what packages were used in the buildroot when the dependent package was built.

Btw, the php-cli/readline issue has been addressed in F11+ (F10 is EOL shortly, so I didn't bother there). It now links to libedit instead.
