Обсуждение: undefined symbol PQconnectionNeedsPassword referenced by file pg_ctl.o

Hi, i tried to compile postgres 8.3.13 but  i  got the  next error:
Undefined                       first referenced
symbol                              in file
PQconnectionNeedsPassword           pg_ctl.o
ERROR: Symbol referencing errors. No output written to pg_ctl

cc -b elf -O pg_ctl.o  -L../../../src/port -lpgport
-L../../../src/interfaces/libpq -lpq -L../../../src/port   -lpgport -lz
-lreadline -lsocket -lm  -o pg_ctl

8.3.11  without this problem.

Apparently you're trying to link against a pre-8.3 version of libpq.
I'd guess the linker is for some reason picking up an old library in
/usr/lib rather than the one in ../../../src/interfaces/libpq (if
indeed there is anything there).
