is it better to use 64 bit IDE or 32 bit now days?
lazarus / 3-General

In the past, it was recommend that coders use the win32 with the win64
cross build option instead of the 64 bit IDE.
Is that still true?
I build for both targets but I finally was able to track down a memory
release bug when I used the 64 bit target option as it gave me more
info with line numbers.
If the 64 bit cross build helped me there, would it be better if I
used the 64 bit IDE with the 32 bit cross builder?
FYI: I'm limited to the Lazarus 2.0 releases by management at this
time.

If you can only use the release versions of both Lazarus and FPC (more
so FPC), and you need to compile both x86 and x64 apps, then you are
going to find it better to install the 32-bit version of both, with
the 64-bit cross-compile edition.

The reason for my advice is that you need at least FPC 3.2 Fixes or
Trunk to be able to get the floating point support that will enable
you to do a 64-bit install and the 32-bit cross compile.

See this thread where I asked about this a few weeks back:

http://forum.lazarus-ide.org/index.php?topic=44168.msg310217#msg310217

I went 64-bit by using the fixes versions of both FPC and Lazarus.

Thanks ASBzone, 
I see my original search was too limited to find this link. Will use
that thread for future comments.  It looks like  some knowledgeable
people have given their input on it already.

You could also use the 32 bit IDE twice

that's all and fine and dandy but the real target as we know would be
42 bit.  just have to settle for 64 bit for now

no... it has to be a prime target... either 31 or 61 bits.
