Subject Re: [Axis2] Axis2/C support for AIX?
Date Mon, 16 Jun 2008 10:35:42 GMT

Thanks for your reply, Samisa. But my program seems not going that far, it
crashes at addr_in_handler.c, line 105:
handler = axis2_handler_create(env);
In my source code(1.3.0), axis2_handler_set_invoke is line 113. Using step
in dbx at this line also crashes with Illegal instruction, I guess the
program crashes before this function is called correctly.

Since axis2_handler_create resides in libaxis2_engine.so, which is linked at
link time, while addr_in_handler.o resides in libaxis2_mod_addr.so which is
dynamiclly loaded, I guess this may be some relocation problem. I tried to
copy axis2_handler_create definition from handler.c to addr_in_handler.c and
rename it(avoid symbol conflict), it works. But then it crashes at line 113,
because axis2_handler_set_invoke's definition is also in libaxis2_engine.so.
I don't know what's wrong here, I link the echo with -brtl in order to link
.so library, could that be a problem?
