Hi,

I have a simple code:

==================================================
#include <iostream.h>

class InstructionSet
{
public:
InstructionSet() {
cerr << "InstructionSet CONSTRUCTOR\n";
}
~InstructionSet() {
cerr << "InstructionSet DESTROYED\n";
}
};

InstructionSet globalInstructionSet;

int main(int argc, char * argv[])
{
cerr << "main\n";
return 0;
}
==================================================

When I built and ran this on IBM AIX with xlc version 5, I got

main

But on the other UNIX platforms (HP, SGI, Alpha, Linux, SUN), I got

InstructionSet CONSTRUCTOR
main
InstructionSet DESTROYED

Do you know why the Aix build is not calling the default constructor?

The build commands on Aix are

Compiling rdc.cpp
xlc -q64 -O2 -DAIX5 -DRS64 -DRS6000 -qnolm -DUSE_AIX_LOCAL -c
-o rdc.o rdc.cpp -I. -Iunix -I../../include/
Creating rdc
xlc -q64 -O2 -DAIX5 -DRS64 -DRS6000 -qnolm -DUSE_AIX_LOCAL -o
rdc rdc.o -bh:4 -bpT:0x10000000 -bpD:0x200000 -L. -L../../bin/ -lbsd

-q64 -lpthreads -lC -lC -lc -lxlf90 -lm

Many thanks in advance,
Chris

Because you are not building your executable correctly.

Never do this ^^^^^^^^^^^^

Instead, use appropriate compiler driver ('xlC' in this case)
to link your executables.

Thanks a lot! Using xlC solved the problem.
