Plugin works in 1.10.07 but not in 1.11.03 (normal ?)

Question

Hello,

After a long way :D I have written my RTP Extensions. So first I would like to say thanks, because I get help from that forum.

I have written my Plugin and have compiled it with MS VS 2012 with the source from the stable 1.10.07. Now I have a 32 bit plugin.dll. That is very nice and Works with the stable Version 1.10.07 very good.

Now I would like to change to Version 1.11.03. So I have Install that Version, but with my Plugin Wireshark don't start. I have then download the source code and build my Plugin with the 1.11.03 and with that new dll Wireshark start with the Version 1.11.03.

Now my Question: Is it possible to make a plugin what works in 1.10.07 and 1.11.03 without recompile?

My Plugin looks like: I Post the code but i dont think it is important for my Question

#include "config.h"
#include glib.h
#include epan/packet.h
#include "packet-rtpExtensions.h"
void proto_register_rsExtensions(void);
void proto_reg_handoff_rsExtensions(void);
static int rtpext = 0x0001;

static int rtpproto= 0x80;
static void
proto_register_rsExtensions(void)
{   …    }
static void
extdissectxtensions(tvbuff_t *tvb, packet_info *pinfo, proto_tree *tree)
{   …. }
static void
dissectxtensions(tvbuff_t *tvb, packet_info *pinfo, proto_tree *tree)
{   …. }
void
proto_reg_handoff_rsExtensions(void)
{
dissector_handle_t dis1;
dissector_handle_t dis2;
rdeo = create_dissector_handle( extdissectxtensions, foo);
dissector_add_uint("rtp.hdr_ext", rtpext , rdeo );
rEx = create_dissector_handle( dissectxtensions, foo);
dissector_add_uint("rtp.pt", rtpproto, rEx );
}

Have a nice day

Hi,

too many internal APIs have changed between 1.10 branch and the 1.12 development branch to ensure that you have a plugin compatible between major versions.

That's the drawback with plugins: you need to provide one library per major (stable) version. You can use compilation flags to have a single source code, but the recompilation is unavoidable unfortunately.

For your information, once a major version is frozen (1.10.0 or 1.12.0), we try to keep the APIs stable between minor versions (1.10.1, 1.10.2, ...) so as to ensure compatibility.
