1. kdevelop -> libpq-fe.h ( part II )

   Eduardo Kotujansky <ekotuja@brasilnet.net> — 2000-08-15T18:20:20Z

    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

   collect2: ld returned 1 exit status
   gmake: *** [usa_postgresql] Error 1
   *** failed ***
   
   I am still in problem.

   What about the libpq and libecpg? Use -lpq -lecpg

   If you use the gcc C compiler try a command something like this:
   
   gcc -o program program.c -lpq -I/usr/include/pgsql
   
   #  'program'      		is name of executable to produce
   #  'program.c'    		is name of source file being compiled
   #  '-lpq'  	 		means "link against libpq"
   #  '-I/usr/include/pgsql'	directory that contains libpq-fe.h
   
   See 'info gcc'  for full rundown on this compiler.
