The libpg-fe.h is in /usr/include/pgsql/libpq-fe.h so i did: #include "../include/pgsql/libpq-fe.h" and the message changed: c++ -O0 -g3 -Wall -o usa_postgresql main.o main.o: In function `exit_nicely(pg_conn *)': /root/usa_postgresql/usa_postgresql/main.cpp:13: undefined reference to `PQfinish' main.o: In function `main': /root/usa_postgresql/usa_postgresql/main.cpp:47: undefined reference to `PQsetdbLogin' /root/usa_postgresql/usa_postgresql/main.cpp:52: undefined reference to `PQstatus' /root/usa_postgresql/usa_postgresql/main.cpp:55: undefined reference to `PQerrorMessage' /root/usa_postgresql/usa_postgresql/main.cpp:63: undefined reference to `PQexec' /root/usa_postgresql/usa_postgresql/main.cpp:64: undefined reference to `PQresultStatus' /root/usa_postgresql/usa_postgresql/main.cpp:67: undefined reference to `PQclear' /root/usa_postgresql/usa_postgresql/main.cpp:75: undefined reference to `PQclear' /root/usa_postgresql/usa_postgresql/main.cpp:81: undefined reference to `PQexec' /root/usa_postgresql/usa_postgresql/main.cpp:82: undefined reference to `PQresultStatus' /root/usa_postgresql/usa_postgresql/main.cpp:85: undefined reference to `PQclear' /root/usa_postgresql/usa_postgresql/main.cpp:88: undefined reference to `PQclear' /root/usa_postgresql/usa_postgresql/main.cpp:89: undefined reference to `PQexec' /root/usa_postgresql/usa_postgresql/main.cpp:90: undefined reference to `PQresultStatus' /root/usa_postgresql/usa_postgresql/main.cpp:93: undefined reference to `PQclear' /root/usa_postgresql/usa_postgresql/main.cpp:98: undefined reference to `PQnfields' /root/usa_postgresql/usa_postgresql/main.cpp:100: undefined reference to `PQfname' /root/usa_postgresql/usa_postgresql/main.cpp:104: undefined reference to `PQntuples' /root/usa_postgresql/usa_postgresql/main.cpp:107: undefined reference to `PQgetvalue' /root/usa_postgresql/usa_postgresql/main.cpp:110: undefined reference to `PQclear' /root/usa_postgresql/usa_postgresql/main.cpp:113: undefined reference to `PQexec' /root/usa_postgresql/usa_postgresql/main.cpp:114: undefined reference to `PQclear' /root/usa_postgresql/usa_postgresql/main.cpp:117: undefined reference to `PQexec' /root/usa_postgresql/usa_postgresql/main.cpp:118: undefined reference to `PQclear' /root/usa_postgresql/usa_postgresql/main.cpp:121: undefined reference to `PQfinish' collect2: ld returned 1 exit status gmake: *** [usa_postgresql] Error 1 *** failed *** I am still in problem.
