If you're running Windows XPchances are it's bit. However, if you're on Windows 10Windows 8Windows 7or Windows Vistathe chance that you're running a bit version goes up considerably. Knowing if your copy of Windows is bit or bit becomes very important when installing device drivers for your hardware and choosing between certain kinds of software.

One quick way to tell if you're running a bit or bit version of Windows is by looking at information about your operating system installation in Control Panel. However, the specific steps involved depend a lot on which operating system you're using. Another quick and simple way to check if you're running a bit or bit version of Windows is to check the "Program Files" folder. There's more on that at the very bottom of this page.

How to compile 32-bit program on 64-bit gcc in C and C++

Open the Control Panel. You can check your Windows system type much faster from the Power User Menubut it's probably speedier that way only if you're using a keyboard or mouse. With that menu open, select System and then skip to Step 4. If so, select System and then skip to Step 4. System command from Run or Command Prompt. Find the System area, located under the large Windows logo.

Within there, next to System typeit will say either bit Operating System or bit Operating System. The second bit of information, either xbased processor or xbased processorindicates the hardware architecture.

It's possible to install a bit edition of Windows on either an x86 or x64 based system, but a bit edition can only be installed on x64 hardware.

Locate the System area below the oversized Windows logo, and look for System type among the other statistics about your computer. This will report either bit Operating System or bit Operating System.

We've come up with what we think is a reasonable solution using macros, but was curious to know if people could think of cases where this might fail or if there is a better way to do this. Please note we are trying to do this in a cross-platform, multiple compiler environment. I've found the most effective way to do this is the following.

First I pick my own representation. Then I find out what all of the major compilers use for determining if it's a 64 bit environment or not and use that to set my variables. Unfortunately, in a cross platform, cross compiler environment, there is no single reliable method to do this purely at compile time. Therefore, the only reliable method is to combine 3 simple checks :. Choose any method to set the required define variable.

I suggest the method from JaredPar:. Now it's all done at compile time :. The reason why this works well is that it forces you to think of every single case in advance, and not rely on sometimes flawed logic in the "else" part to execute the correct code. I used this technique among many others to write a 30, line project that worked flawlessly from the day it was first deployed into production that was 12 months ago.

You should be able to use the macros defined in stdint. Some all? Not sure why, since it's a standard file. That won't work on Windows for a start.

Longs and ints are both 32 bits whether you're compiling for 32 bit or 64 bit windows. I would think checking if the size of a pointer is 8 bytes is probably a more reliable route.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I am using windows 7 bit. I don't know the gcc installed on this computer is bit or bit. Windows 7 support both and bit programs. You can inspect the output of gcc -v or you can use the more direct option -dumpmachine. The first option allows you to discover if GCC is capable of multilib so that it can compile both 32 and bit binariesthe second option will only return the default target if I am not mistaken.

MinGW-w64 - for 32 and 64 bit Windows

I don't remember which setup. And I would hate to mess up my cygwin installation. Run uname -m. If it's bit, you will instead see iiior i The other answers address the OP's question, but if you're like me and use both flavors of Cygwin, it's useful to know which one you're using for more than just running setup.

If I know my script is running on Cygwin, I prefer. I can use that in an "if" block like this:. Of course, you can also use "uname -a" with "grep" in an if statement. It's a matter of personal preference. NateT gives the correct command to "print the machine hardware name" according to "uname --help":.

Here's the entire output of "uname -a". On bit you've got no choice, right? Update: Thanks to theDrake. Ironically, since around Feb the WOW64 in the string has changed to WOWso although checking for WOW is probably safe now it seems the "machine hardware name" might indeed be safer than the "kernel name".

Cygwin does seem to be take backwards compatibility seriously according to that thread, but also note that under MSYS2 you'd need to rely on the "machine hardware name" anyway and not the "kernel name":. Learn more. Ask Question.

Let's take an example temp. Case code compiled on bit ubuntu using gcc temp. Case code compiled on bit ubuntu using gcc -m32 temp. Output: Error: cannot run on bit ubuntu. As amdn posted in comments above, it could be due to some missing library for bit. Since it was not working earlier, I installed gcc-multilib and some auto updates of Ubuntu and it has started working. Learn more.

Could you not run a bit Linux instance in a VM? GoBusto it will take some time to setup actually. So we managed to get a bit cross compiler over MAC. What is the exact error message you get when you try to run the cross-compiled binary? There should be no difference between the output of a bit compiler building a bit binary and a bit compiler building a bit binary.

An interesting exercise would be doing a diff on a disassembly of the two different binaries, and including this info in your question. You should likely be including the architecture in your compilation command eg. Also, selecting -m32 does not necessarily restrict the compiler to using only instructions which are available on the i Active Oldest Votes.
