Thanks for this, and for the answers from other users.

Ultimately I chose to:

pkg upgrade -f

pkg upgrade -f -r poudriere

The second command was probably to broad. In retrospect I could have 
forced just three from my poudriere repo:


drm-kmod
gpu-firmware-kmod
openzfs-kmod

As far as I can tell, just one casualty: SimpleScreenRecorder, which 
does record and save, but fails to cancel (before beginning a recording) 
or close (after saving a recording); it stops responding.


I'm now building multimedia/simplescreenrecorder with poudriere, if 
installation from this repo does not resolve the issue then I might 
repeat 'pkg upgrade -f' alone plus just the three kmods from poudriere.


(Afterthought, note to self: maybe SimpleScreenRecorder is a casualty of 
a routine upgrade that I performed a few hours earlier; there was much 
KDE stuff at the time.)

Alexander,

it would seem that

find /usr/local/*bin* /usr/local/lib* -type f \
| xargs ldd -f '%p|%A\n' 2>/dev/null \
| grep '^not found' | cut -d '|' -f2 \
| xargs pkg which -q | sort -u

is prone to false positives, since ldd is sensitive to LD_LIBRARY_PATH, viz.:


Yes. Firefox, LibreOffice/OpenOffice come to my mind directly. There  
may be others. I expect those to be rare (compared to the size of the  
ports collection), but if you encounter some false positives, it's  
probably a big package. Either way, "locate $missing_lib" is a good  
idea here.


[...]

So make sure you look into what exact library is missing and if
it's actually somewhere "non-standard",
that directory should be in LD_LIBRARY_PATH.


Temporary for the run of this check, yes.

Bye,
Alexander.

Alexander,

it would seem that

find /usr/local/*bin* /usr/local/lib* -type f \
| xargs ldd -f '%p|%A\n' 2>/dev/null \
| grep '^not found' | cut -d '|' -f2 \
| xargs pkg which -q | sort -u

is prone to false positives, since ldd is sensitive to LD_LIBRARY_PATH, viz.:

$ find /usr/local/*bin* /usr/local/lib* -type f \
| xargs ldd -f '%p|%A\n' 2>/dev/null \
| grep '^not found' | cut -d '|' -f2 \
| xargs pkg which -q | sort -u
firefox-84.0_2,2

$ export LD_LIBRARY_PATH=/usr/local/lib/firefox
$ find /usr/local/*bin* /usr/local/lib* -type f \
| xargs ldd -f '%p|%A\n' 2>/dev/null \
| grep '^not found' | cut -d '|' -f2 \
| xargs pkg which -q | sort -u
$

So make sure you look into what exact library is missing and if
it's actually somewhere "non-standard",
that directory should be in LD_LIBRARY_PATH.

Identifying broken applications following careless use of make -DBATCH_DELETE_OLD_FILES delete-old-libs

[Graham Perrin]

Re: 
 
I made careless use of:


cd /usr/src && make -DBATCH_DELETE_OLD_FILES delete-old-libs

– then found applications such as LibreOffice no longer working as 
expected. Resolved (I believe):


pkg remove inkscape libreoffice && pkg autoremove && pkg install 
inkscape libreoffice


Please: how can I positively identify other applications that I might 
have broken through careless deletion of old libraries?
