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.
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 8.2-2 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. -- Take care.
