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.

#include <iostream>

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?

Do you have any ideas why does wxHyperlinkCtrl doesn't work on Linux?It has an error which says..."/usr/include/wx-2.8/wx/gdicmn.h:215: undefined reference to 'vtable for wxHyperlinkCtrl'"Do I have to include a certain library so that it will work in Linux? I try to compile it in windows and its succesful.'m having a problem on Linux guysinitialize the wxHyperlinkCtrl like this... wxHyperlinkCtrl* hyperlink1 = new wxHyperlinkCtrl();and included #include <wx/hyperlink.h> Is there something missing on it?...

When the following little C program is compiled with gcc it does not get a compile error even though the function atof is undefined. If I change it to xatof then it goes get an "undefined reference" error. (I knowthat atof is a library function, and I know that it resides in stdlib.h But since I did not include stdlib.h I would think that it would give me an error). What am I missing here?

I am trying to update gtk+. I have installed pango-1.26.2 and glib 2.22.5. I see some error information, from google i know that it is old glib library fault. Ichecked. pkg-config --modversion glib shows 1.2.*** and pkg-config --modversion glib-2.0 shows 2.22.5. It looks like gtk+ using older 1.2.**.

I'd like to learn debugging techniques as much as to solve this particular problem. While trying to build yad 0.5.1:
Code:
yad-notification.o: In function `yad_notification_run':
/tmp/yad-0.5.1/src/notification.c:330: undefined reference to `gtk_status_icon_set_tooltip_text'
According to the source package's README file, "Yad depends on gtk+ only. Minimal gtk+ version is 2.12.0". I checked /var/log/packages and found gtk+2-2.14.7-i486-4 is installed.
Inspecting /tmp/yad-0.5.1/src/notification.c showed that gtk_status_icon_set_tooltip_text is a function. So it should be declared in the gtk+2-2.14.7 header files (or not?).
Checking:
Code:
c@CW8:/usr/include/gtk-2.0$ find . -name '*.h' -exec grep gtk_status_icon_set_tooltip_text {} ;
[no output]
Is this enough analysis to justify reporting an issue? Is there any more I can do before logging an issue?
OS: Slackware 13.0 32-bit.

The downloaded package checksums OK. Netsearching for gtk_status_icon_set_tooltip_text finds no pages.
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'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?
