General :: (.data+0x4): Undefined Referenec To '_rand'

May 12, 2010

I am trying to compile legacy a code that worked well with f77 and g77 on linux platform. I am trying to use g95 since f77 and g77 are not available. The code is mostly in fortran and uses few c functions among. I am getting the undefined reference error for rand:

(.data+0x4): undefined referenec to '_rand'

I am defining my own function RANDOM and rand in an include file but I am not sure why it is failing to link and giving me such error?

external rand
double precision rand
#define RANDOM rr(nq)

why g95 is giving me such issues?!

General :: Undefined References And Linking In WordNet

Jan 19, 2011

I'm writing a C program using WordNet, just a very basic one to test out if everything was working fine, but I'm getting undefined references. I linked to the library and compile with

Code:
gcc prog.c -L/usr/local/WordNet-3.0/lib/libWN.a -I/usr/local/WordNet-3.0/include/
This seems to be the only wordnet library to link to, but I'm still getting the error

Code:
/tmp/cc4C3I3S.o: In function 'main':
prog.c:(.text+0x21): undefined reference to 'is_defined'
prog.c:(.text+0x48): undefined reference to 'findtheinfo'
collect2: ld returned 1 exit status

I feel it must be an error with the way I'm going about trying to link the files.

General :: Connect To A Test Database - Undefined Reference To `sqlite3_open'

Jun 7, 2010

I have a little C++ program that I am attempting to connect to a test database.

#include <iostream>
using namespace std;
#include <sqlite3.h>
int main ()
{
int rc;
[Code]....

When I compile this code, I get the error: undefined reference to `sqlite3_open' I added sqlite3 package using the command 'apt-get install sqlite3'. Unfortunately the sqlite3.h header file was not installed in /usr/include, so I downloaded the SQLite3 dist., untarred it and copied the sqlite3.h file to /usr/include. I saw on a previous message that I would need to link the library. The only library file in /usr/lib is libsqlite3.so.0, so the command g++ -lsqlite3 still gives me an error.

General :: Compile And Link A Program To Test Parapin - Undefined Reference

Dec 17, 2010

I'm trying to compile and link a program to test parapin.

Code:
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include "parapin.h"
int main(int argc, char *argv[])
{ ...
[Code]....

It looks like the library is found (no error anyway) but the functions in it are not seen. Text at the beginning of libparapin.a includes function names as used in the test program, and parapin.h declares them.

Debian :: Undefined Function Mysql_connect()

Jul 31, 2010

I am trying to connect to my mysql database using php but I am getting the error "Fatal error: Call to undefined function mysql_connect()".

I checked phpinfo() and there is no reference to MySQL. I believe this means that my install of PHP doesn't support MySQL. Do I need to uninstall and reinstall with a version of PHP with MySQL support? If so how should I do this and how do I get a version of PHP that supports MySQL?

Programming :: Dlopen And Undefined Error ?

Mar 22, 2010

I've been told to move my code from MFC to linux platform, and so I did, trying to keep as much as I can on the way, now, I had a dll and application, the application I rewrote all anew while the dll I only made changes so it'll be an ".so" file, now, when I try to link using "dlopen", I get the message "undefined symbol: _ZN5ImageC1EiiPh", now, Image is a class in the DLL, which even makes its own ".o" file for the DLL itself. I just can't understand why it happens. I use Image in functions which are not in Extern "C", but the functions I want to use don't use it. Also, I have many globals in the DLL, (because that's how the DLL was written in the past) but none of them is Image...

Is the problem with the fact I include a c++ class in the DLL? How can I solve such a problem? I tried messing with how I link it, but I think that's not the issue here.

I use g++ and -rdynamic --export-dynamic -ldl -lrt for the application

and for the dll I use -shared -Wl,-soname, and -lm, and for the .o files of the dll -Wall -fPIC (although for some reason it doesn't let me do it through the makefile and I needed to do that by hand, which was a little weird. I put it in tag, I put it in line, but it still did nothing...

OpenSUSE Install :: Undefined Video Mode 346 ?

Aug 16, 2009

While booting SUSE 11.1 64-bit I get these messages:

Code:
Probing EDD (edd off to disable)
Undefined video mode 346
Press Enter to see video modes available
And then a 30-second wait.

Is it advisable to set edd off? If so, how?

Would that get rid of the 30-second wait?

The video card (NVidia GeForce 6150 LE) and the monitor (ViewSonic VA2216W-4) seem to work fine with SUSE, so I don't understand the "Undefined video mode" message.

Having said that, I've seen much better text-rendering than, for instance, this messageboard. See attached image. Could that be a card/monitor problem? It looks better in Vista with the same hardware. So does Firefox in general.

Programming :: Undefined Reference To Function While Linking

I am trying to add some function to the c++ project (calling function) and the called function are in C. And i am getting error "undefined reference to "Hello(int,int)" " while linking. It is compiling correctly. It is linking to header file mention in the calling function. This header file has definition to the c - called function. Do you thinking having c files into C++ project will be a problem? Should I remove <stdio.h> in c files?
