 Posted: Mon Sep 27, 2004 9:24 am Post subject: how do i link 3rd party lib on windows ? |
 |
|
Hello there
I'm pretty new to C, so this is probably an elementary question....
I'm trying to write a simple c program that calls a function in a
third party library. I would then like to link this to a dll. The
files that were supplied to me by are :
a .lib file
a .h file
a .dll
So... I've written a simple C program like so :
#include "SecondTry.h"
#include <stdio.h>
#include "jni.h"
#include "qabwved.h"
JNIEXPORT void JNICALL Java_SecondTry_helloWorld(JNIEnv *env, jobject
obj)
{
printf("Hello world !n");
//calling external lib function...
QABatchWV_Startup(1);
return;
}
I'm using the lcc-win32 compiler / linker on Windows 2000.
It compiles fine with the following command line :
lcc -Id:j2sdk1.4.2_03include -Id:j2sdk1.4.2_03includewin32
-Id:devcsecond_tryjava -Id:devQas_appC SecondTryImpl.c
The problem starts when trying to link it with :
lcclnk -dll qabwved.lib secondtryimpl.obj -o secondtry.dll
I'm getting the following error :
secondtryimpl.obj .text: undefined reference to
'__imp__QABatchWV_Startup'
The function QABatchWV_Startup is defined in the .h file that I've
received. I assumed that the implementation would be in the .lib that
I've received.
Any ideas ? I've tried a few things already, and am really stuck at
the moment.

You may have more luck on a newsgroup devoted to your compiler/platform.
This is not, strictly speaking, a C or C++ question.

lcc-win32 is a non-standard C system, and off-topic on both c.l.c
and c.l.c++. Almost anything crossposted to c.l.c and c.l.c++ is
off-topic on at least one. However this will be on-topic in
comp.compilers.lcc, to which I have cross-posted this and set
followups. Go there for any replies.
c.l.c is devoted to the portable C language only. This does not
include any extensions and/or third party libraries.
