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.

I have a RHEL4.8 machine, and I am trying to install the following libxml2-2.7.8 and libxslt-1.1.26 The OS installed versions are: libxml2-2.6.16-12.6 and libxslt-1.1.11-1.e14_7.2 I installed libxml2-2.7.8 and it appears to have installed successfully. However, when I attempt to build and install libxslt, it complains about some undefined references when linking to libxml2 which I believe are not in the old version (but do exist in the new one I installed). I am not able to erase the old versions and I am not able to update to the ones I want. I am at a dead-end at the moment and I am not sure how to proceed.

Since I could not find the cairo dock package on packman for openSUSE 11.3, I decided to build the package from source. I ran the configure script first and then gave a build using make. I get undefined reference errors for the following symbols 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?

I am using Centos 5.4 with gcc v4.1.2. If I take a bunch of .o files and I then link with my main.o to form an executable then this links and executes just fine. If however, I try to create an archive file (.a) using 'ar rus xxx.o yyy.o etc' and then try to link the resulting .a with my main.o then I get 'undefined symbol' linker errors and I don't understand why.

I'm trying to build a shared library, and am receiving several undefined reference linking errors. Specifically, ffmpeg linked with libx264. I'm aware that this is not an appropriate forum for questions specific to ffmpeg or libx264. In order for one library / application (ffmpeg) to reference another library (libx264), the linker has to know where the referenced library (libx264.so) is located in the file system.
I'm pretty sure the linker knows where libx264.so is, because I receive a different error message when I run ffmpeg's configure script if the linker can't find libx264.so. In general, should running the install target of a make file be preferred over specifying the appropriate paths in the CFLAGS and LDFLAGS environment variables? I've tried both, and it doesn't seem to make a difference in regard to my error which method I choose.
How exactly is a library referenced? My error messages are
/root/ffmpeg/libavcodec/libavcodec.so: undefined reference to `d26'
/root/ffmpeg/libavcodec/libavcodec.so: undefined reference to `d22'
/root/ffmpeg/libavcodec/libavcodec.so: undefined reference to `d2'
/root/ffmpeg/libavcodec/libavcodec.so: undefined reference to `d20'
/root/ffmpeg/libavcodec/libavcodec.so: undefined reference to `d24'
/root/ffmpeg/libavcodec/libavcodec.so: undefined reference to `d0'
/root/ffmpeg/libavcodec/libavcodec.so: undefined reference to `q1'
If I can find out what library 'd26', 'd22', etc. are declared in, I should be able to resolve the undefined references. What exactly are 'd26', 'd22', etc.? Are these functions, classes, or something else? How can I find out what functions / classes are defined in a particular library?

I have created a simple test class - Mortgage, with the class declaration in the .h file and the class's methods defined in the .cpp file. (mortgage.h && mortgage.cpp, respectively) Straight up C++ 101 as far as I can tell. I instantiate the class in the main() function, which is defined in practice.cpp. Using Geany on Ubuntu, both the practice.o and mortgage.o files are created, but then I get a linker error: undefined reference to class::functionName
I get it for each function. If the mortgage.cpp file is foremost in the editor when I click "build", then I get the undefined reference to main() error, if practice.cpp is foremost (where the main() function is) then I get undefined reference to Mortgage::Mortgage(), and all the rest of the functions defined for that class. How do I get the linker to know where my object files are so it will link them in? Or is the problem somewhere else entirely?

I have written an OpenGL based program which uses i.a. libjpeg that I want to link statically so I can send it to someone who doesn't have all the libraries needed installed to allow for a dynamically linked executable to run. As such I tried with giving the [b]-static[b] parameter to gcc.
Code:
x86_1$ make
gcc -O3 -c jpegloader.c
gcc --std=c99 -O3 -c --std=c99 -I/usr/include -L/usr/X11R6/lib main.c
[code].....
Why would gcc claim that I'm missing GLUT? This works perfectly fine when I do dynamic linking -- i.e. omitting the -static argument.

I'm trying to math all class references in a C++ file using grep with regular expression. I'm trying to know if a specific include is usuless or not, so I have to know if there is a refence in cpp. I wrote this RE that searches for a reference from class ABCZ, but unfortunately it isn't working as I espected:
grep -E '^[^(/*)(//)].*[^a-zA-Z]ABCZ[]*[*(<:;,{& ]'
^[^(/*)(//)] don't math comments in the begging of the line ( // or /* )
.* followed by any character
[^a-zA-Z] do not accept any caracter before the one I'm searching (like defABCZ)
[]* any white space (I can have something like ABCZ var; )
[*(<:;,{& ] followed by ( * < : ; , & { (I cant get #define "ABCZ.h" or ABCZdef for example)
Well, I can get patterns like this:
class Test: public ABCZ{
class Test: public ABCZ {
class Test : public ABCZ<T>
[code].....

I have a library that I have ported from Windows, and is not a derivative work of Linux. The library is subject to copyright law, and I can't disclose the source. I would like to link a GPL application to this library, and want to know if the linking would cause the library to be GPL. If the library becomes GPL, is there some other way (kernel loadable module?) that I can keep my library from becoming a work of GPL?

After I downloaded the source for lua, I followed the install instructions, doing...
make linux install
make generic install
I've also done the make test and it passes, printing out Hello World, from Lua 5.1. However, I can't link to the lua libraries in CodeBlocks. I know where lualib.a is (usr/local/lib) which I set in my Search Directories for the linker. I still get error messages like...
undefined reference to lua_isstring
P.S. I had this running on Windows via Visual Studio.

I have 5 FTP users that upload files (and subdirectories) in their home directory, i need to mirror theese directories beetween them and with a "master" directory (accessible from a 6th user). Files can contain spaces or others special caracters. All the files are in the same filesystem, and i want to use hard link because i don't want to waste 5 time the space of a single file. I tried with find but i cannot handle spaces in it.

I have a third party static library (libSTATIC.a) that I cannot recompile into a shared library. I want to create a shared library (libSHARED.so) that uses the C functions in the static library. Is it possible to do this? In other words, when linking a C program with gcc by using the -shared flag, is it necessary that all all libraries invoked in the program (even low level libraries such as libc for example) be available as shared libraries as well?

I can't figure out why I'm getting seg fault in this program im making in c++. The program is of the game "Mastermind" board game which I'm sure many of you might have heard of.im fairly new to coding c++. I do not know why I'm getting seg fault error when trying to compile as I'm not using any pointers? or trying to access memory that was not allocated to me?

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?!

I have 10.10 64-bit on a Fujitsu T900. the hard drive has windows seven as well (64-bit). The win7 is the orginal from the manufacture. the boot log originally had (in this order): Win7, Windows Vista (about 100 MB not sure why but can't remove), recovery partition. I put ubuntu on after those three. Some times when the computer goes into suspend mode from ubuntu it will not wake up after wards. the only option it to power i down manually. when it comes back up there is now a second reference to ubuntu in the boot log. this has happened several times. there are now four valid references to ubuntu in the boot loader. I need to remove three of them, but i'm concerned that removing them will compromise ubuntu. Also I'm not sure where the boo log in windows seven is.

I am developing a system in Python that includes an engine and multiple front ends. I am doing the engine and a curses front end together and will add additional FE's later. My problem is that I don't know how to get my front end to import the modules from the engine. I have them set up in Eclipse (using Pydev) as separate projects, but in the same workspace.
I've been a developer for years, but this is my first Python project, and I'm also fairly new to Eclipse. I guess my question is, How do I set up the references to other projects of my own making?

A while back a disk error caused /var/lib/dpkg/status to go south - completely corrupted. I managed to rebuild it with the help of a script i found online, but now there's a package called libghc6-edison in limbo on my install. It has no sources, as it was custom built, and i cant seem to find the references to this thing. Apt cache shows that it exists, synaptic gives me an error in CLI every time i launch it referring to this package -Traceback (most recent call last):
I've tried grepping all the files in /var/lib/dpkg to no avail. Any ideas where else this information could be stored? i need to find all the references to the package and purge them. It seems to preven me from successfully pulling off a do-release-upgrade (in a VM for testing) as well as doing a remastersys dist (have to do remastersys backup instead).
The package was never available in Lucid, if i remember correctly, i had to compile it myself and debianize it, but i cant seem to find the sources on my build VM or anywhere in the installed end-product OS.

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.
