32bit-64bit
Should I use Python 32bit or Python 64bit
64 bit version will allow a single process to use more RAM than 32 bit, however you may find that the memory footprint doubles depending on what you are storing in RAM (Integers in particular). For example if your app requires > 2GB of RAM, so you switch from 32bit to 64bit you may find … Read more
Determining 32 vs 64 bit in C++
Unfortunately there is no cross platform macro which defines 32 / 64 bit across the major compilers. I’ve found the most effective way to do this is the following. First I pick my own representation. I prefer ENVIRONMENT64 / ENVIRONMENT32. Then I find out what all of the major compilers use for determining if it’s … Read more
CentOS 64 bit bad ELF interpreter
You’re on a 64-bit system, and don’t have 32-bit library support installed. To install (baseline) support for 32-bit executables (if you don’t use sudo in your setup read note below) Most desktop Linux systems in the Fedora/Red Hat family: pkcon install glibc.i686 Possibly some desktop Debian/Ubuntu systems?: pkcon install ia32-libs Fedora or newer Red Hat, … Read more
Missing include “bits/c++config.h” when cross compiling 64 bit program on 32 bit in Ubuntu
Adding this answer partially because it fixed my problem of the same issue and so I can bookmark this question myself. I was able to fix it by doing the following: sudo apt-get install gcc-multilib g++-multilib If you’ve installed a version of gcc / g++ that doesn’t ship by default (such as g++-4.8 on lucid) … Read more
Microsoft.Jet.OLEDB.4.0′ provider is not registered on the local machine
I found a solution for this problem. The issue I described in my question occured basically due to the incompatibility of the Microsoft.Jet.OLEDB.4.0 driver in 64 bit OS. So if we are using Microsoft.Jet.OLEDB.4.0 driver in a 64 bit server, we have to force our application to build in in 32 bit mode (This is … Read more
Why do 64-bit DLLs go to System32 and 32-bit DLLs to SysWoW64 on 64-bit Windows?
I believe the intent was to rename System32, but so many applications hard-coded for that path, that it wasn’t feasible to remove it. SysWoW64 wasn’t intended for the dlls of 64-bit systems, it’s actually something like “Windows on Windows64”, meaning the bits you need to run 32bit apps on a 64bit windows. This article explains … Read more
How can I test a Windows DLL file to determine if it is 32 bit or 64 bit? [duplicate]
A crude way would be to call dumpbin with the headers option from the Visual Studio tools on each DLL and look for the appropriate output: dumpbin /headers my32bit.dll PE signature found File Type: DLL FILE HEADER VALUES 14C machine (x86) 1 number of sections 45499E0A time date stamp Thu Nov 02 03:28:10 2006 0 … Read more

How to determine whether a given Linux is 32 bit or 64 bit?
Try uname -m. Which is short of uname –machine and it outputs: x86_64 ==> 64-bit kernel i686 ==> 32-bit kernel Otherwise, not for the Linux kernel, but for the CPU, you type: cat /proc/cpuinfo or: grep flags /proc/cpuinfo Under “flags” parameter, you will see various values: see “What do the flags in /proc/cpuinfo mean?” Among … Read more
