Linux c串連 postgresql資料庫

#include<stdio.h>#include<stdlib.h>#include<libpq-fe.h>#include <string.h>int main(){    PGconn *conn; const char *conninfo="host=localhost dbname=cloud user=cloud password=cloud";  //  char conninfo[100];  //  sprintf(conninfo,"dbname=%s user=%s password=%s","cloud","cloud","cloud");    conn=PQconnectdb(conninfo);    if(PQstatus(conn)==CONNECTION_BAD)    {       fprintf(stderr,"connection to %s failed",conninfo);       PQerrorMessage(conn);    }    else printf("connection ok");     PQfinish(conn);    return 0;}

gcc編譯：gcc -I /usr/include/postgresql/ postgresql.c -o pgsql -lpq

 

 

yum install postgresql-devel

如果沒有include 和 lib 兩個目錄...... 說明你還沒裝開發devel包 redhat上應該有其開發包
