_OpenLibrary not found

dlsa · 22 October 2021, 19:07

Hi,

I have a Vampire V4 running AROS. It has VBCC installed in it.
I want to use the exec call OpenLibrary to load a dynamic lib.
The code compiles, but in the link phase it cant find the code for it.

What do I have to do ?

Thanks,
Regards

What libraries are you including in you’re linking? amiga.lib?

As Deimos said, you will usually link against amiga.lib (

-lamiga

) when calling AmigaOS functions. You also want to

#include <proto/exec.h>

, so the compiler does not have to rely on stub functions from amiga.lib but can generate inline code for the call.

Including the proto header file always makes sure that the optimal AmigaOS calls for your current compiler are being used.

I didn't mention, but I configured VBCC to use NDK_3.9 headers also.
I have set the lobosv3: to the target's lib directory that includes amiga.lib from the VBCC binary directory tree.

the .library files are in LIBS:

I placed the -lamiga switch on the command and it worked.

Thanks,
Regards
