AIX xlc and gcc/g++ Question

[Fang-Pin Chang <fchang at qualcomm dot com>]

Hi!  I am trying to use a library (archive) that was built with GNU C/C++
with a C program that is built using AIX's xlc compiler.

The library has C interfaces that manipulates C++ objects declared within
the library as either static and/or global variables, and the C program
will be calling these C interface functions.

While the C program compiles and links fine, it core dumps upon execution.
The reason seems to be that the constructors for these static and/or global
C++ objects aren't being called.  I wrote a simple test library plus some
test code, and these seem to bear out my reasoning for the aforementioned
core dump.

However, the C program I am trying to write will run just fine if I compile
it with the gcc compiler.  But, I need it to work with the xlc compiler.

To get the C program to compile/link using xlc, I am linking in the
libgcc.a and libstc++.a as well.

What am I not doing or doing incorrectly?

My system is as follows:

	AIX RS/6000 OS level v4.2.0.0
	GNU C/C++ 2.8.1
	xlc 4.3 (I think)

Any advice/help would be appreciated.  Thanks!
