proper way to report(?) conflicting files being installed?

proper way to report(?) conflicting files being installed?

[Robert P. J. Day]

  long story short, colleague was adding packages to a build and ran
into error wherein both of:

  * autoconf-archive
  * gnome-common

were trying to install a couple identical m4-related files. some
quick googling produced this:

  https://patchwork.openembedded.org/patch/142467/

with the self-evident solution being applied to gnome-common to
"uninstall" the two conflicting files:

--- a/meta-oe/recipes-gnome/gnome-common/gnome-common_3.18.0.bb
+++ b/meta-oe/recipes-gnome/gnome-common/gnome-common_3.18.0.bb
@@ -17,4 +17,15 @@  DEPENDS = ""

 FILES_${PN}-dev = ""

+# ax_code_coverage.m4 and ax_check_enable_debug.m4 are in gnome-common only
+# because older versions of autoconf-archive didn't have them yet. Now they

+RDEPENDS_${PN} += "autoconf-archive"
+DEPENDS_append_class-native = " autoconf-archive-native"
+

  it *appears* that solved the problem, which raises the question --
should this patch be applied to the current gnome-common recipe? that
patchwork entry dates back to 2017 ... should it have been applied at
some point?

The currently implemented solution is:
# Default to enable autoconf-archive to avoid conflicts
PACKAGECONFIG ??= "autoconf-archive"
PACKAGECONFIG[autoconf-archive] = "--with-autoconf-archive, --without-autoconf-archive, autoconf-archive"

It is not clear to me why this gives the user to disable it
instead of unconditionally enabling it.

  i was a bit confused by that as well, but i figured i just didn't
read it carefully enough.

  this does seem backwards ... if both gnome-common and
autoconf-archive currently try to install those two m4-related files,
doing the above pretty much *assures* an installation conflict, unless
you apply the patch i linked to earlier at:

  https://patchwork.openembedded.org/patch/142467/

where (as i read it) the gnome-common patch uninstalls them, but then
drags in autoconf-archive just to make sure they're installed. so what
*should* this look like?

No, --with-autoconf-archive makes gnome-common not install the 
conflicting files.

I should point out that gnome-common is dead upstream and mostly unused 
now, so if you find a recipe using it do check that it is actually needed.

  in fact, just earlier this aft, i sent the short note, "um ...
what are you doing that needs that gnome-common thing?"

  i await the reply.
