Aug 20, 2013 · Since that was the last significant reason to create new 32-bit Cygwin installs on 64-bit Windows systems, it is unlikely that you have a good reason to do that today. The biggest advantage to using 64-bit Cygwin is access to greater amounts of memory. There are two very different ways the advantage presents itself:
A note about 32-bit Cygwin. The limited address space of 32-bit Windows means that random failures in the fork(2) system call are more likely. Therefore, we recommend using 32-bit Cygwin only in limited scenarios, with only a minimum of necessary packages installed, and only if there's no way to run 64-bit Cygwin instead.
Switch from 32-bit Cygwin to 64-bit Cygwin, if your OS and CPU support that. With the bigger address space fork() is less likely to fail. Try setting the environment variable CYGWIN to "detect_bloda", which enables some extra debugging, which may indicate what other software is causing the problem. See this mail for more information
Nov 27, 2014 · Cygwin 32-bit is usually installed in c:\cygwin and the 64-bit cygwin is installed in c:\cygwin64. So in summary, if you need 32-bit capabilities install the 32-bit cygwin and all the necessary packages you need to complete your task. NOTE: 32-bit programs WILL run on 64-bit windows platforms.

Nov 5, 2015 · 1 Answer. Sorted by: 5. The names are quite clear to me: cygwin32-gcc-g++ is a compiler for 32 bit cygwin. gcc-g++ is the basic 64 bit compiler (you probably must install this one). mingw-gcc-g++ is a 32 bit compiler for native 32 bit Windows. mingw64-x86_64-gcc-g++ is a 64 bit compiler for native 64 bit Windows.
The installation should take about 30 minutes, depending on which mirror you choose in step 9 and network congestion. Visit Cygwin’s web site. Find the heading marked “Installing Cygwin”. Choose the 64- or 32-bit version of the .exe file and run it. This initial dialog box tells you some important information.

Step 2: Run Setup to Select, Download & Install Cygwin Packages. Run " setup-x86_64.exe " ⇒ Install from Internet ⇒ select a directory (avoid installing in "Program Files" because of that "blank" character) ⇒ choose "Local Package Directory" which saves the downloaded installation files ⇒ Direct Connection ⇒ choose a download mirror site.
