symbol lookup error: /home/quantum6/build_libs/lib/libreadline.so.7: undefined symbol: UP

真奇怪。

config.status: creating src/include/switch_version.h.in
gawk: symbol lookup error: /home/quantum6/build_libs/lib/libreadline.so.7: undefined symbol: UP
config.status: error: could not create src/include/switch_version.h.in
Makefile:1312: recipe for target 'Makefile' failed
make: *** [Makefile] Error 127
