In a gcc build script terminating with the instruction
gcc -w -static -o myexe -O3 ./myarchive.a -lreadline -lncurses -lm
I have suddenly started getting very many instances of both of
ld: /usr/src/debug/readline-8.2-2/terminal.c:nn various: undefined reference to `{various}'
ld: /usr/src/debug/readline-8.2-2/display.c:nn various: undefined reference to `{various}'
and the build fails.
It's a while since I attempted this build of myexe (myarchive has been unaltered for years) and the attempt is triggered by a reported bug in gcc -pg after update that has been corrected.
I don't know whether it is a change in readline (libreadline.a) or gcc that has possibly caused the glitch (and obviously I cannot and do not expect anybody to debug my build for me) but is this glitch familiar to anybody through current or previous experience, or by appearance, that means you could point to cause or possible cause?
Thank you!

The problem was with readline not gcc
and I assume originates in myarchive.a and the required switch -lreadline in the gcc line
rather than in readline: nevertheless I reverted both libreadline-devel and libreadline7
from 8.22 to 7.03 and the problem went away.

Please provide a few examples which include the actual texts of "nn various" and
`{various}' especially where any prefixes vary.
Did you also upgrade/downgrade libncurses-devel concurrent with
libreadline-devel as they are dependent?
Why suppress all warnings -w from the ld (or any) phase of compilation?
Those warnings could tell you what causes an issue.

No I didn't upgrade / downgrade libncurses-devel concurrently with libreadline-devel.
In fact after upgrading back to 8.2-2 and confirming the failed build I retained all current and up-to-date
and made _just_one_change_: I extracted the single file libreadline.a from libreadline-devel-8.1-2.tar.xz
(i.e. just one reversion to 8.1 not two to 7.0) and substituted it in place leaving everything else as for 8.2-2
including libreadline.dll.a and confirmed that this single substitution allowed the build.
I suppress the warnings because there are so many of them! I can supply them but for the moment the issues
that prevent a successful build using libreadline.a (8.2-2) are listed in the attached text file.
Thank you very much for taking an interest.
