Topic 2: Patches for packages failing with -fno-common

Important because: This bug blocks the upgrade to gcc-10

How to find packages with this bug?

• Many packages are linked to the bug tracker ticket bug #705764
  • List of open bugs with package names can be seen here
  • Same as above, but with bugs with either a "PATCH" or "PullRequest" keyword filtered out, here. If a bug has either of those keywords, it is unlikely it requires further user action.

How to fix this bug?

• First, check, if there is a patch upstream already
• Write a patch, send it upstream and link it in the bug of the package.
• gcc-10 porting notes about fno_common

I still do not know how to start. Could you provide an example workflow?

Larry wants to fix one of his favorite packages.

• Larry picks one package in bug #705764
• Larry adds the bug number to the "looking at" column in his row in the Activity Tracker (and adds a row for himself if one does not already exist) so others can see this bug is being worked on
• net-misc/networkmanager: Fails to compile with -fno-common bug #706000
• check upstream - is there a fix?
• if there is, decide if a patch or a version bump makes more sense.
• download or write a patch, copy it to /etc/portage/patches and test it
• report upstream, and link the upstream bug/ticket in Gentoo's Bugzilla
• now that the task is completed, Larry should update the Activity Tracker by moving the bug number from the "looking at" column to the "completed" column
