[AXISCPP-533] Inter shared library exception handling broken on Linux

• Type: Bug
• Status: Reopened
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: current (nightly)
• Component/s: Basic Architecture
• Environment: GNU specific (as far as I know)

Description

On Linux, actually on systems where the compiler and common libraries are g++ and gnu and glibc, exception handling between shared libraries is broken. It is broken because the same class in different shared libraries is treated differently so that an HTTPTransportException thrown by a channel library does not match "catch (HTTPTransportException& e)" in the transport library.

Refer to http://gcc.gnu.org/faq.html#dso for details.

The fix is to load the subordinate library with RTLD_GLOBAL flag.

As far as I know this is GNU specific but may apply to other platforms.

It's possible that others are not seeing this because the context in which I am running Axis is from within an application that itself dynamically loads a library that depends on Axis.

Cheers,

Tim
