[PATCH] package_deb: Remove version from Provides Field

[PATCH] package_deb: Remove version from Provides Field

[Ricardo Ribalda Delgado]

According to Debian Policy Manual. Chapter 7.1

All of the fields except for Provides may restrict their applicability
to particular versions of each named package. This is done in
parentheses after each individual package name; the parentheses should
contain a relation from the list below followed by a version number, in
the format described in Version, Section 5.6.12.

This Fixes the following warning:

root@qt5022:~# apt-get update

...

Reading package lists... Done
W: Ignoring Provides line with DepCompareOp for package
pkgconfig__pkg-config__
W: You may want to run apt-get update to correct these problems

Shouldn't this actually make a version comparison, i.e. if <condition>
then emit the Provides, otherwise don't (looking at the package version
for comparison)?

I can imagine having multiple versions of a recipe, some with provides
and some without, all using the same code.

Cheers,

Richard

Re: [PATCH] package_deb: Remove version from Provides Field

[Ricardo Ribalda Delgado]

Hello Richard

It is ok to have Provides, but they should not have a version number.
If they have a version number a nasty warning appears (as you can see
on the patch). The provided patch just clears all the versions but
keeps the Provides

We could "fix" dpkg to support versioning, but I believe it is better
to just remove the version number from the Provides.

Cheers!

We can also do the version comparison in package_deb.bbclass itself. I
believe there is some code somewhere which can understand the different
constraints.

ok, but for the next release wont be a good idea to fix the warning in dpkg?
