Bug 530116 – dev-qt/qtsql-4.8.6 depends on virtual/mysql-5.6 while dev-qt/qtsql-5.3.2 depends on virtual/mysql:0/0 which is virtual/mysql-5.5

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description farmboy0 2014-11-22 13:20:31 UTC]

Qt5 needs dev-qt/qtchooser which depends on Qt 4.8.6.
dev-qt/qtsql-4.8.6 depends on virtual/mysql-5.6 while dev-qt/qtsql-5.3.2 depends on virtual/mysql:0/0 which is virtual/mysql-5.5.

Reproducible: Always

$ grep virtual/mysql *.ebuild
qtsql-4.8.5.ebuild:	mysql? ( virtual/mysql )
qtsql-4.8.6-r1.ebuild:	mysql? ( >=virtual/mysql-5.6-r2:=[${MULTILIB_USEDEP}] )
qtsql-5.3.2.ebuild:	mysql? ( virtual/mysql:= )

That is intended and not a bug.

You just have to rebuild qtsql:5 against a version of virtual/mysql that satisfies the dep in qtsql:4. Portage should offer to do that automatically if you try to upgrade virtual/mysql.

Output from emerge:

!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

virtual/mysql:0

  (virtual/mysql-5.6-r2::gentoo, ebuild scheduled for merge) pulled in by
    =virtual/mysql-5.6-r2 required by (dev-qt/qtsql-4.8.5::gentoo, installed)
    (and 6 more with the same problem)

  (virtual/mysql-5.5::gentoo, installed) pulled in by
    virtual/mysql:0/0= required by (dev-qt/qtsql-5.3.2::gentoo, installed)

What was the emerge command that led to that output?

[Comment 4 farmboy0 2014-11-22 15:32:06 UTC]

Take your pick:
emerge -uDN world
emerge --oneshot virtual/mysql
emerge --oneshot virtual/mysql:0
emerge --oneshot virtual/mysql-5.6-r2

[Comment 5 Davide Pesavento (RETIRED) 2014-11-22 15:43:47 UTC]

Try emerge --oneshot virtual/mysql qtsql:5

[Comment 6 Davide Pesavento (RETIRED) 2014-11-22 19:45:41 UTC]

In any case, the dependencies are correct.
