This appears to be an upstream bug; despite that we configure with
'--with-readline="$SAGE_LOCAL"', the corresponding '-L...' is missing in
the linker command such that your system's libreadline gets picked up.
Or maybe not:
## Readline.
# Check whether --with-readline was given.
if test "${with_readline+set}" = set; then :
withval=$with_readline; if test "${withval}" = no; then
use_readline=no
else
use_readline=yes
fi
else
use_readline=yes
fi
...
[A couple of readline-related tests, probably disabling it.]
...
I.e., R's 'configure' only supports enabling/disabling use of readline,
but not specifying a non-standard location [that way].
This is actually a regression introduced by the "clean-up" in #13443
[1], which removed adding "-L${SAGE_LOCAL}/lib" to LDFLAGS (and similar
for CPPFLAGS, but the latter in contrast works); if LIBRARY_PATH is
already set, ${SAGE_LOCAL}/lib gets *appended* instead of prepended (in
sage-env).
Ursula, can you confirm that `LIBRARY_PATH` is set in your shell?
E.g., what does the following give?
$ ./sage --sh -c 'echo $LIBRARY_PATH'
