On a 32-bit machine: Any CPU: runs as a 32-bit process, can load Any CPU and x86 assemblies, will get BadImageFormatException if it tries to load an x64 assembly. x86: same as Any CPU. x64: BadImageFormatException always. On a 64-bit machine: Any CPU: runs as a 64-bit process, can load Any CPU and x64 assemblies, … Read more
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
Another way(without adding i386 architecture)… sudo apt-get install libc6-i386 lib32stdc++6 lib32gcc1 lib32ncurses5 sudo apt-get install lib32z1 Ref: Fix Android adb on Ubuntu 13.10 64bit
You can find out a lot about the Python version you’re running via the platform module (the sys module also has a few simple helpers) On Mac OS X, you can run a “fat binary” with your chosen architecture with, for example, arch -i386 /usr/bin/python I do not recommend altering /usr/lib/python itself (with the lipo … Read more
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
Intrinsic functions are really fast, but still are insufficient for a truly cross-platform, compiler-independent implementation of log2. So in case anyone is interested, here is the fastest, branch-free, CPU-abstract DeBruijn-like algorithm I’ve come to while researching the topic on my own. const int tab64[64] = { 63, 0, 58, 1, 59, 47, 53, 2, 60, … Read more
Here is what I’ve done in a previous project, which will require the manual edition of the .csproj file(s). You also need separate directories for the different binaries, ideally siblings of each other, and with the same name as the platform you are targeting. After adding a single platform’s references to the project, open the … Read more
This trick was never officially supported by the language and you have been getting away with it to date due to the implementation specifics of the 32 bit compiler. The documentation is clear: Nested procedures and functions (routines declared within other routines) cannot be used as procedural values. If I recall correctly, an extra, hidden, … Read more
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
One of the more interesting ways I’ve seen is this: if (IntPtr.Size == 4) { // 32-bit } else if (IntPtr.Size == 8) { // 64-bit } else { // The future is now! } To find out if OTHER processes are running in the 64-bit emulator (WOW64), use this code: namespace Is64Bit { using … Read more
