One line can be done, output 32 or 64.You can use "getconf word_bit" and "getconf long_bit" to get the number of digits for WORD and LONG, and 32 and 64 for 64-bit systems respectively.The reference code is as follows:
Copy Code code as follows:
Ldconfig
If [$ (getconf word_bit) = ' $ '] [$ (getconf l
The origin of the problem
Cross-compilation is very important (should be said to be necessary) for embedded development, but the recent use of cross-compilation tools on physical Linux machines has often encountered a problem: the cross-compile tool version is correct, the installation steps are correct, and the environment variable is set correctly, but it is running ARM-LINU-GCC- V has been reported bash:/OPT/ARM-2009Q3/BIN/ARM-LINUX-GCC: No error in the file or directory, is very depressing,

The history of 64-bit computing is quite rich and interesting. Companies such as Cray have started using 64-bit registers in their systems in the 70 's, but the truly pure 64-bit computations didn't really come until the 90 's. Th
Even if you haven't compiled advanced applications for nanoelectronics, aerodynamic, Molecular static, cell lifecycle modeling, and so on, maybe the following 32 rules are as follows, it will help you port programs to a higher-level processor.
Recently, it seems that everyone has been talking about 64-bit computing, such as amd athlon 64 processor laptops, Apple

Basic
1. VS has only x32bit version, no x64 version.
2. DOTNET framework including basic library (system. *), CLR, JIT compiler, etc, have x32 and x64 version. for example, I have a c: \ windows \ Microsoft. net \ framework and a C: \ WINDOWS \ Microsoft. net \ framework64 folder.
3. a dotnet Assembly only contains il before first time running, so at that time, it's not process-specific (x32/x64 ). by default, the platform target is "any CPU. "Remember that our C # Or VB compiles to Il, And that

Most Linux distributions have versions for x86_64 processors. Typical x86_64 processors include ADM Athlon II and Intel Xeon. These Linux distributions all have their own software sources that provide Binary packages for all the application software it supports. If you are satisfied with the Linux installation method, you may not need to run a 32-bit program.
