Changes between using 32-bit and 64-bit API?

Hi everyone,

In the past I have written code utilizing OpenSim 3.0's 32-bit libraries. I now need to combine this code with some other libraries which are 64-bit. I was pleased to see that OpenSim 3.1 is available in both 32 and 64 bit.

My questions is, are there any significant changes/limitations when switching to 64-bit? Are the libraries that come with the 64-bit OpenSim in fact 64 bit, and hence should compile in a 64 bit program?

Thanks for your help.

Marc

Hi Marc,

There's no difference between the 32 bit and 64 bit API, just different compilers for the same code base, so you should be able to recompile your code against the 64-bit libraries and you're good to go. Depending on what part of the API you used in 3.0, you may need to make minor changes to upgrade to 3.1 but that's independent of whether you're using 32 or 64 bit compilers.

Hope this helps and please let us know how it goes,
