Mixing 32-bit & 64-bit libraries

[Donatoll]

Hello!
It's possible to compile a program linking sametime with 32-bit and 64-bit libraries?

I think it's not possible, but i ask it 'cause I can't ensure it.

Thanks in advance!

No, you can not do it.
If you application is 32 it can be linked only with 32 bit libs and 64 bit app can be linked with 64bit libs.

If you try to mix you will get Errors while linking.

Shalom,

If you want to use a library providing a particular function, call it function schmo, and its provided by 32 bit and 64 bit libraries, you must make a choice.

Memory management for 32 and 64 bit libraries are different, and I'd say in general if you need a 32 bit library you should stay pure 32 bit.

Obviously since the world is going 64 bit, you are better off long term and from the development cost perspective to go pure 64 bit.

As Srikrishan and SEP have said, you can't mix architectures. There is talk about doing magic in Aries but that is in the future.

You'll need to figure out what is the common bit size of any third party libs you are using.

Note the default is +DD32 on HP-UX and will probably stay that way until 128 bit machines come along. If you don't need that large address space, you may want to stay with 32 bit.

Thankis a lot people!
I really was asking a question with no sense.

Best regards!
