Compiling a C++ program including libpq-fe.h by the command Code: g++ -I/usr/include -L/lib -lpq my_program.cpp for access to a PostgreSQL database results in the error Code: undefined reference to '_PQconnectdb'
View 4 RepliesI have a program that is completed under Linux, it requires library tidy, PCRE and libcurl, which could be found in Cygwin too.
I could compile my linux program through Cygwin and produce an EXE file, however it do require 'cygwin.dll' installed by the users.
I am wondering if I could have someway to produce out a stand-alone EXE file that could run independently from Cygwin ? ( I don't mind to combine that cygwin.dll and the EXE together for a larger EXE file).
New to this kernel stuff But not too new to C/C++. I'm trying to compile the linux kernel on a PC, that is running Windows XP 32 bit, using Cygwin. I keep getting the error saying:
Error: Not ELF
make[2]:*** [scripts/mod/elfconfig.h] Error 1
make[1]:*** [scripts/mod] Error 2
make:***[scripts] Error 2
Every time I try to compile it from the main directory of the source, which I hope is what I'm supposed to do, I always get this.
I'm interested in modding an open-source turn based game called Advanced Strategic Command or ASC, but to do that I need bunch of libraries. Installing those libraries is very easy in linux, I know but the thing is I'm working with windows in which the building of the libraries is a bit more complex, as you probably know. One of those libraries is the ligsigc++, I'm using VC++ but haven't been successful in building the libsigc++ in VC++. I considered making my life easier with Cygwin (a unix shell for windows) and simply executing ./Configure, Make. I's worked like a charm and the library dll it produced is named cygsigc-2.0-0.dll which made me wonder is compiling a library in cygwin to be linked with VC++ perfectly ok? That is is there any difference in compiling in cygwin and VC++?

I have been using gcc to compile C programs.
I want to know what exactly is the meaning of Compiling a C program.
I checked
cc -S prog.c
will give an .S file and if you analyze the hexdump I saw some assembly instructions.
So what does the compiler do which is not required in case of interpreted languages?

I'm trying to make my program as small as possible. Currently it's down to 17.8 KB, but I'd like to get it smaller (I know, I'm insane). Is there a way to not use the "#include" directive to include the entire header, but rather to just load only the stuff I need? For example, I just want to include 'sprintf' and 'printf' from stdio.h, not the entire header. Is this possible? Or am I misunderstanding some fundamental element here?

I have been able to find repos that contain php 5.3.2 and Pg 8.4.4, but I can not find on that provides an RPM where php is built against Pg 8.4. It is usually 8.1. I also have not been able to figure out if yum can force a rebuild based on the fact that I actually got the correct versions installed, just not using each other. I simply would like to get php built with Pg 8.4 and have it work.
