Hi Steve, Have you tried the Debug version or Release version?
I just tried the Debug one and it worked fine, but the release version failed every time. Regards, Shan -----Original Message----- From: Shan Wang [mailto:[email protected]] Sent: 26 March 2009 23:58 To: [email protected] Subject: RE: Exception thrown from qpidcommon.dll on windows Hi Steve, I built 0.5-release and it has exactly the same problem. What did you mean by building qpidcommon/client as static lib? I wonder if I have made any mistakes during builing process. Thanks, Shan BTW there is a minor problem for 0.5-release windows build: it seems the solution hasn't put the header files under gen/ directory to deploy/include, so it was complaining about missing files like "qpid/framing/amqp_structs.h" -----Original Message----- From: Steve Huston [mailto:[email protected]] Sent: 26 March 2009 18:37 To: [email protected] Subject: RE: Exception thrown from qpidcommon.dll on windows Hi Shan, The case I tried is: Simple program runs, calls LoadLibrary to load messaging.dll which is linked with qpidclient.dll and qpidcommon.dll. This failed with qpidcommon/client built as static libs because of the TSS issue you refer to. When qpidcommon/client built as DLLs, everything works.
