Hi, Now that I've gotten by earlier problems with the module I'm working on (see thread "Re: UNSOLVED was Re: SOLVED was Re: How to compiling/link/use Apache module that uses shared library?"), I am trying to get my module to work with the stuff in that libobaccess.so. This .so is part of Oracle's Access Server SDK (ASDK).
The problem I'm running into now is that there's an initialization call in the library that I need to make, ObConfig_initialize() that is suppose to initialize the SDK environment, but when I call that (it takes either NULL or a const * char as parameter), it's blowing up (Apache aborts). I *think* that the problem is that the libobaccess.so is actually C++, with a bunch of wrapper-type C functions to wrap the C++ functions, i.e., so my module (which is C) calls a function, and inside obaccess.so the function calls a C++ function)., and it's probably blowing up because the Oracle code doesn't know anything about Pool memory, but rather uses C++ new, etc. Here's a gdb backtrace showing this: In callAccessGate()... In callAccessGate(): About to set handler... In callAccessGate(): returned from set handler In callAccessGate(): About to call ObConfig_initialize()... Program received signal SIGABRT, Aborted.

(gdb) So, my code calls ObConfig_initialize() then it appears that that calls ObConfig_initialize() which is presumably a C++ function. In general, is there any way to handle this problem/situation if it's memory allocation (inside libobaccess.so) related? Thanks, Jim
