How to manage dependent dlls to a bundle [message #96170] Wed, 29 August 2007 04:32 Go to next message
Eclipse UserFriend
Hi,

I am trying to set a bundle that uses a DLL 'A' that is linked to DLL
'B'. The DLL 'A' is found correctly but can not be loaded because the
system does not found DLL 'B'. The only way I have found is to add DLL 'B'
to the system path...

Is is possible to do this using the "Bundle-NativeCode" property or
with an other method??

Xavier

Do a call to System.loadLibrary(B) first, then System.loadLibrary(A). B will be cached, and A will see B in memory when it's loaded. You'll still need to use the Bundle-NativeCode header for both DLLs.

This seems to work in a windows environment and maybe mac. But I've
found this does not work so well on Linux systems. There is an open
issue against OSGi for this, but it looks like we cannot solve it in a
good way unless the VM is enhanced.

There was a workaround; set LD_LIBRARY_PATH prior to calling the actual loadLibrary() to include the extracted dll's directory, and then reset it afterwards. I don't know if you can do such a thing on Windows though.
