Re: Axis2/C, C++ and 'undefined symbol: __gxx_personality_v0'
Hi Manjula,
Yes, you are right. I removed setting LD_PRELOAD from my script that
starts the axis server, the test still runs OK.
And yes, I have seen the mention in the Axis2/C FAQ about using
'extern C'. I just have to suggest that the FAQ mention using
'extern C' specifically with axis2_get_instance() and
axis2_remove_instance() functions - initially I have added it to all
functions in the sample code but these two :)
Thank you,
alex.

now with httpd :)

Senaka, after I did something (I don't remember exactly what, I have
done a lot of experimenting this morning) I also stopped getting
undefined __gxx_personality_v0 and the server just started crashing
(SIGSEGV); and when I run gdb on the core file, I also saw the that
the crash was occurring in the AXIS2_SVC_SKELETON_INIT().
But then, after some more experimenting, I added 'extern C' to the
functions axis2_get_instance() and axis2_remove_instance() in my test
service, and the test run successfully. Well, at least this is what I

So, two things so far: a) preload the libstdc++.so, and b) use 'extern

name?)

I've tried with two versions: first, I downloaded and compiled latest
released Axisc/2 v. 1.3.0 from the http://ws.apache.org/axis2/c; after
seeing this error, I downloaded a WSO2 Web Services Framework for

This release, as I understand, includes Acis2/C version 1.2. The same

Hi Alex,
As it says, add,
#ifdef __cplusplus
extern C{
#endif
In the top of your file, after including the headers. And, add,
#ifdef __cplusplus
}
#endif
at the very end. This way, you will be able to set extern C for all the
methods in the source file.
I too didn't require the LD_PRELOAD when I tried.

'echo service' example from the Axis distribution, renamed it to .cpp
file and compiled/linked it with 'g++' compiler. No compile errors
reported, the resulting .so library I copied to the services
directory, together with the corresponding services.xml file.
I compiled a sample client that tries to send something to my new service.
Than I strarted an 'axis2_http_server' application and run the client,
which failed with a SOAP error message about failure to load a dll.
I found in the Axis2/C source code the place where it loads the .so
file (axutil_class_loader_load_lib() in file 'class_loader.c'), and
added debug log message that reports into the log the exact text of an
error as it is returned by dlerror() function, not just a message that
if failed to load a library, like this (after line 156 of the file
'class_loader.c'):
if (!dl_handler)
{
AXIS2_LOG_DEBUG(env-log, AXIS2_LOG_SI,
AXIS2_PLATFORM_LOADLIB error: [%s],
AXIS2_PLATFORM_LOADLIB_ERROR);
...
...
...
after recompiling the Axis and running the test again, I see in the
log following message:
class_loader.c(159) AXIS2_PLATFORM_LOADLIB error:
[/home/alexb/wsfcpp-repo/services/my_service/libmy_service.so:
undefined symbol: __gxx_personality_v0]
I understand that the real problem is that the axis2_http_server
application is not compiled/linked with the g++ support libraries.
Several years ago I had similar problem when writing a C++ module for
Apache's httpd server, but there the solution was to use an httpd's
directive 'LoadFile' to load the g++ runtime library into the httpd
environment before loading my C++ module with the LoadModule
directive.
So the question is, does anyone knows how to make the
axis2_http_server to load the g++ runtime library before it loads a
C++ .so service library?
For the record, I'm doing all this on the Ubuntu 7.10, and here is a
result of running 'g++ --version:
$ g++ --version
g++ (GCC) 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)
