gcc-3.4.3 and HP-UX 11.11

[Deierling Andreas]

Hi,

 

I try porting our software from AIX to HP-UX with g++ 3.4.3 on a 64-bit PA2-risc machine (64-bit kernel).

We are using g++ binary version from HP gcc-3.4.3-sd-11.11.depot (my short tries to build 3.4.3 failed...)

 

The developers stuck solving a mysterious error where a double value passed to a method is

destroyed on his way through the stack...

 

Because the software runs fine under AIX (with g++ 3.3.1) it might have something to do with the

tools : compiler or (HP-)linker.

 

My questions:

Which combination of tools are recommended ? Is it worth using the gnu linker ? I read somewhere it isn't...

Is it worth building my own g++ 3.4.3 ?

It seems that my g++ creates 32-bit objects. How can I manage it to make 64-bit objects ?

 

Thanks,

Andreas
