Same mirror data with both Cygwin setup.exe?

Same mirror data with both Cygwin setup.exe?

[Gery .]

Hi,

Is it advisable to run both Cygwin 32- and 64-bit setup installers with the same downloaded set of packages from a unique mirror? I have 6GB data downloaded from a mirror, I downloaded that while running step 64-bit installer. I want to remove that Cygwin 64-bit and now install the Cygwin 32-bit (so, use the setup 32-bit) but with the same data mirror.

Thanks for any pointers,

Gery

Once upon a time, it could cause a problem, but now that setup.exe's 
download tree structure includes $arch, there is no conflict.

I assume you are doing this because you need some package that is only 
in Cygwin 32?  If so, which one?

If you used setup-x86_64.exe to do the downloading then that will have 
downloaded 64-bit packages only. If this is the case then you will have 
some more downloading to do to get the 32-bit packages. However, you 
don't have to do a full install - if you select only those packages you 
need during the installation process then that will reduce the amount 
you need to download.

But otherwise, you can install 32-bit and 64-bit Cygwin side-by-side, 
and from the same mirror.

Cheers,

Dave.

Thank you Warren and David for your commentaries about my question. Well, I use Seismic Unix and have installed before in cygwin 32-bit without problems. I tried it a couple of days in my Cygwin 64-bit and it crashed or gave strange data outputs. This seismic unix also uses x11 programs, they did not worked properly either. Why? I have no clue. That's why I'll try cygwin32 now. I'll download everything again, so I can test this from a fresh installation.

Thank again for your answers,

Cheers,

Gery
