Hi, I'm not sure I understand it properly: does a 64 bit OS run/compile code faster than a 32 bit OS on the same system? We're using 64 bit OSs where I am and it seems to only cause compatibility issues with legacy and proprietary software. (We're running Ubuntu 9.04 Jaunty amd64) ...
Folks, what is the best way to kill an established connection from the shell in linux? Looks like there are 'tcpkill' and 'cutter' tools available, however, on my gentoo amd64 tcpkill is disabled by the 'amd64' keyword and cutter, when used, prints an error "openning /proc/net/ip_conntrack: No such file or directory". Is there any ot...
The vcvarsall.bat that does setup de build environment let you choose between x86 | ia64 | amd64 | x86_amd64 | x86_ia64. First option is obvious for 32bit, but the question is: what would be the optimal option between the other 4 if you want to build for 64bit and you want to run on all 64 bit machines. Let say that you don't have ti...
Yesterday I learned that inline assembly (with the __asm keyword) is not supported under Microsoft Visual C++ when compiling for AMD64 and Itanium targets. Is that correct? And if so, does anyone know why they would not support inline assembly for those targets? It seems like a rather big feature to just drop... ...
I've been teaching myself GNU Assembly for a while now by writing statements in C, compiling them with "gcc -S" and studying the output. This works alright on x86 (and compiling with -m32) but on my AMD64 box, for this code (just as an example): int main() { return 0; } GCC gives me: .file "test.c" .text .globl main .type main...
I know that if I want to compile a 32 bit .exe for windows on Linux I can just install and use the mingw32 package (e.g. apt-get install mingw32) on linux. What if I want to compile a windows .exe that is 64 bit? Is there tools or a method to do this? ...
I'm using Ubuntu Server 9.10 AMD Phenom 2 cpu g++ (Ubuntu 4.4.1-4ubuntu9) 4.4.1 trying to run the application pftp-shit v 1.11, which runs successfully until the remote file list is going to be saved (into .pftp//pftpfxp--). The following code in tcp.cc is executed successfully: int outfile_fd = open(name, O_CREAT | O_TRUNC | O_RDWR |...
I want to write a simple batch file where i want to setup a environment variable based on the machine architecture. It is as below: set ARCH=%PROCESSOR_ARCHITECTURE% echo %ARCH% if %ARCH%==x86 ( set JAVA_ROOT=C:\Progra~1\Java\j2re1.4.2_13 ) else ( set JAVA_ROOT=C:\Progra~2\Java\j2re1.4.2_13 ) echo JAVA_ROOT is %JAVA_ROOT% On 64-bi...
Hello, I have a PC with AMD FX CPU (Do not remember if it was FX51 or FX60) it is 64Bit does it means that I can run 64Bit Guests? even if it does not have the Visualization extensions in the CPU? ...
How do I use RIP Relative Addressing in a Linux assembly program for the AMD64 archtitecture? I am looking for a simple example (a Hello world program) that uses the AMD64 RIP relative adressing mode. For example the following 64-bit assembly program would work with normal (absolute addressing): .text .global _start _start: mo...
I know that in the past OpenCV was based on IPP and was optimized to run on Intel CPUs. Is this still the case with OpenCV 2.0? Thanks, SW. ...
This is a chronological continuation of this question. I have simplified my board so it runs well with the DDK version of BulkUSB on 32bit versions of XP and Vista, but I'm not able to install it on Vista 64.(built with amd64 fre) I've been able to make windows recognize the files it needs to install, using both BulkUSB and USBSamp, but ...
Hello all, I am currently recompiling gtk+ and dependencies from source (I have no other choices). All my custom packages are installed in a specific custom point (let's call it /packages) (it can seem odd but this time again, I have no other choices). When I try to recompile pango, it needs freetype. Freetype is already installed in ...
