Using Codeblocks on 64-bit PC - What should I know?

(1/2) > >>

resander:
I have been using a 32-bit Compaq desktop for general use and program development (the last 3-4 years using Codeblocks IDE) for many years. The Compaq is now beginning to show signs of age and (reluctantly - it has been such a dependable workhorse) I have started to look for a desktop replacement.

Looking at the usual outlets Dell, Amazon etc, it would appear the large majority of PCs offered nowadays are 64-bit. I probably should get one of these, but what would the consequences be:

Q1. Is Codeblocks 32-bit and will it run as it is without changes on a 64-bit PC?

Q2. I will still need to generate code (and test using Codeblocks) for 32-bit PCs. Can I do this easily? Also, of course, I will need to generate and test for 64 bit.

Q3. I have many Codeblocks 32-bit projects. Can I still maintain these on a 64-bit PC without making any changes to code or Codeblocks usage?

Q4. Anything else that I should know?

Yes - additionally, if you install a (MinGW) 64 bit compiler in parallel, you can also target native 64 bit applications. Even though you are using a 32 bit Code::Blocks. All is fine.

I was just coming back to the thread to add that I was using Ubuntu 10.04 LTS
and your reply was already there! Many thanks for the ultra-fast reply.

Do your replies to q1-q4 apply to Ubuntu too?

Also yes when you have 32bit or 64bit runtime ...

I have been googling a bit on permutations of 'Ubuntu',  '32bit programs' and '64-bit hardware'. From my limited experience the matches I got seem somewhat contradictory.

Some say 'no problem - 32 bit apps run on 64bit Ubuntu', other say '32-bit shared libraries would not be available for 32-bit apps on 64-bit Ubuntu, so the 32-bit app would not work' and a few more like that adding to my confusion.

I am getting 32-bit Codeblocks latest versions via the Ubuntu Update Manager. Jens Lody provides these and it works extremely well.

Q5. Does 32-bit codeblocks work on 64-bit Ubuntu without need to
    install it in some special way. If not, what is involved?
Q6. Do Jens Lody's updates produce 64-bit Codeblocks too?


For the foreseeable future I will continue to develop 32-bit software, so I do not really need 64-bit. But new desktops nowadays come with 64 bit, so I don't have much choice. Besides it would be nice to be able to occasionally transcode video formats which should be faster with 64-bit hardware. On balance I would like to get a 64-bit PC, but if that is going to cause extra work for codeblocks program development then I may have to opt for a second-hand 32-bit PC instead.
