I am getting a undefined reference error to this code. I don't see why. Any help would be great.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <dvdread/dvd_reader.h>
#include <dvdread/ifo_types.h>
#include <dvdread/ifo_read.h>
#include <dvdread/nav_read.h>
#include <dvdread/nav_print.h>

int main() {

	ifo_handle_t *vmg_file;
	dvd_reader_t      *dvd;
		
	vmg_file = ifoOpen( dvd, 0 );
	
	//printf ("YAY %s", vmg_file);
	ifoClose( vmg_file );
}

$ gcc main.c -o rip
/tmp/cc8cLKIQ.o(.text+0x2b): In function `main':
: undefined reference to `ifoOpen'
/tmp/cc8cLKIQ.o(.text+0x39): In function `main':

Hi zippo,

Your code looks okay.

Did you forget to include your dvdread library on the compile/link line?

I would say that is a very strong possablity. I hate to bother you, for a dumb question. How would i go about linking it?! i am useing files in /usr/include/dvdread and they come frome the libdvdread package. Any help and i would be most thankful.

Hi zippo,

I don't know what the dvdread library is called.  Whatever it's called, you 
need to add it to the compile/link line.

Something sort of like...
gcc myapp.c -o myapp -L/usr/dvdread -ldvdread

Ok, but which library?

I am working on a project which calls _disable and _enable interrupt built in functions in the Windows environment. I can build the code with /Oi flag with Microsoft Visual Studio, but failed with gcc compiler with link errors:

 

undefined reference to _disable, _enable. 

 

I have code included, very simple. I am not sure what the problem is, maybe I should link with a specific library. Please advise.

Hi Vincent,

  Undefined references sounds more like a linker problem,
are you linking with the library, where the methods
declared in db2.h are defined?

Yours sincerely,

Bjorn

I'm new to using C and the GNU compilers. I'm trying
to use the Db2 C samples. I am getting a problem with
an UNDEFINED REFERENCE. In a header file called
db2util.h there are some static METHODS that the
compiler is complaining about.

Does anyone know what this means? What kind of problem
is this?

Vincent

This is not really the place to ask for help on installing glibc.  How
about writing to a glibc mailing list?

`t' indicates a local symbol, i.e., one that is not available to other
libraries/objects.
