Hi

I am having problems with my C compiler xlc. It can't find the header files when I try to compile a program. For example, if I:

cc md5.c

It throws me an error that says: include file <sqludf.h> not found. But if I search the sqludf.h header I find it in a path. I already changed the angle brackets to quotes in the md5.c file:

#include file "sqludf.h"

to search for headers in the current directory over system headers, but it still shows the same error "include file "sqludf.h" not found". I also tried to bind the path where the sqludf.h is to the LD_LIBRARY_PATH, but it doesn't work either:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/header/sqludf.h

what can i do to solve this? Thanks in advance

That is failing to find a header file, not a linked library.

I am not familiar with xlc, but with most C/C++ compilers you would need to pass the search directory with -I, like

Or you could simply use the full path in the include directive.

Hi

Thanks for your responses. I put the full path in the include directives and the error messages "sqludf.h not found". are no longer appearing but now it is giving me another error when i try to compile the md5.c file:


ld: 0711-317 ERROR: Undefined symbol: .main
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.

this is the code in md5.c, as you can see there is no main in this file and neither in the md5.h:

#include <stdlib.h>
#include <string.h>
#include <stdio.h>
#include </home/inst6/sqllib/include/sqludf.h>
#include </home/inst6/sqllib/include/sqlca.h>
#include </home/inst6/sqllib/include/sqlda.h>
#include "md5.h"

This isn't a main program, so you cannot create an executable from it.
Anyways, please read this topic: What information to include in a post and how to use [code] tags?

Edit: you seem to wish to create a DB2-database plugin, that calculates MD5.
Try this:
