• Product: Portage Development
• Status: RESOLVED FIXED

[Description gentoo-bugzilla 2007-08-14 22:53:34 UTC]

After calculating dependencies, revdep-rebuild prints:

 * All prepared. Starting rebuild
emerge --oneshot  =emerge: =there =are =no =ebuilds =to =satisfy ="=".
..........
Calculating dependencies /
emerge: there are no ebuilds to satisfy "=emerge:".

 *
 * revdep-rebuild failed to emerge all packages.
 * you have the following choices:
 * - If emerge failed during the build, fix the problems and re-run revdep-rebuild.
 * - Use /etc/portage/package.keywords to unmask a newer version of the package.
 *   (and remove /root/.revdep-rebuild.5_order to be evaluated again)
 * - Modify the above emerge command and run it manually.
 * - Compile or unmerge unsatisfied packages manually,
 *   remove temporary files, and try again.
 *   (you can edit package/ebuild list first)
 *
 * To remove temporary files, please run:
 * rm /root/.revdep-rebuild*.?_*

Here, this should fix it. I didn't anticipate that revdep-rebuild.4_ebuilds could have blank lines in it. Using arrays, blank lines don't matter so much.

[Comment 13 Paul Varner (RETIRED) 2007-08-16 15:54:33 UTC]

Please don't close bugs, until the fix is released.

[Comment 14 Paul Varner (RETIRED) 2007-09-13 00:17:55 UTC]

Blank lines in revdep-rebuild.4_ebuilds are caused by an ebuild no longer being available for the corresponding package in revdep-rebuild.4_packages.  In this case it was for gnome-extra/gtkhtml-1.1.10-r1.

$ svn commit -m "Correctly handle the case where an ebuild no longer exists for a package (Bug #188918)"
