It is particularly worth mentioning that there are many points worth learning about Linux gcc compilation. Here we mainly introduce Linux gcc compilation, including Linux gcc compilation. How can I use php to call a function compiled into the so file? One method is to write a php module (php extension), call the functions in this module in php, and then call the

Ubuntu uses gcc of different versionsDifferent Versions of ubuntu have different gcc, such as ubuntu 10.04 default gcc version is gcc-4.4.1, ubuntu 10.10gcc default version is gcc-4.4.5.However, in actual use, we want to use other gcc
reality, every program has to be a lot of basic underlying library, it is impossible for everyone's code to start from scratch, so the existence of the library is very unusual.The benefit of a shared library is that if different applications call the same library, then only one instance of the shared library is needed in memory.1.4 How library files are generated under LinuxThe suffix of the static library is . A, which is produced in two steps1. Build a heap from the source file compilation. O
, finally, code that can be run on the target platform is generated. the tool chain for cross-compilation can be downloaded from the Internet or created by yourself. however, the compiler is not omnipotent. Due to version restrictions, an error will be reported when compiling some programs. common cross-compilation tool chains include: (1) Cross-2.95.3 tar: This version is earlier and is not used except for compiling Vivi. (2) arm920t-eabi.tgz: 4.1.2 version of the compiler, Eabi support, can co

Compiler stack protection technology in GCC Buffer overflow, represented by stack overflow, has become the most common security vulnerability. Security problems are common. As early as 1988, Morris, a graduate student in the Computer Science Department at Cornell University, used a Unix fingered program overflow vulnerability to write a malicious program and spread it to other machines, as a result, 6000 servers on the Internet were paralyzed, account
Switch GCC, G ++, and gfortran versions in Ubuntu Step 1: use which gcc, which g ++, and which gfortran to view the location. My result is/usr/bin/gcc; /usr/bin/g ++ and/usr/bin/gfortran Part 2: first, let's take a look at the gcc commands installed in your Ubuntu: ls/usr/bin/gcc
How to install other GCC versions in LinuxPreface Sometimes, a fixed version of GCC needs to be installed in Linux to meet work requirements. For example, in Fedora22, compiling the cuda part of OpenCV requires GCC 4.9.X and earlier versions, while GCC of Fedora22 is between 5.1 and 5.3. For example, compiling matcaffe

1 IntroductionThe meaning of GCC is only GNU C Compiler. After so many years of development, GCC has not only supported the C language; it now also supports the ADA, C + +, Java, Objective C, Pascal, COBOL, and Mercury languages that support functional programming and logical programming, and so on. And GCC is no longer just the GNU C language compiler meaning, b
GCC and Linux are excellent combinations. Although they are stand-alone software, Linux relies entirely on GCC to run on the new architecture. Linux also leverages features (called extensions) in GCC to achieve more functionality and optimization. This article discusses some important extensions that explain how to use them in the Linux kernel. GCC's current stab
Address: http://blog.csdn.net/ariesjzj/article/details/7881049 One of the difficulties in Porting a project's build system from GCC to msvc is that the source code uses GCC extension (http://gcc.gnu.org/onlinedocs/gcc/C-Extensions.html), which can be given by adding the compilation option-pedantic. The second difficulty is that some Linux functions are not availa

Pre-compile Compile Assembly Connection Two other important options Debugging Summary Site Link Summary: To read this article, you need to have a basic understanding of the C language. This article will introduce how to use the GCC compiler. First, we will introduce how to use the compiler to compile simple C source code in the command line mode. Next, let's brief
Cygwin/GCC and mingw are both GCC compiling environments in windows, but what are their differences? In actual work, how can we choose the two compilers? Cygwin/GCC can be fully equal to the GCC in Linux, which can be seen from the boost Library Division, GCC in cygwin

I have discussed a lot of gcc compilation issues, all of which come from compiling gcc4.7.2 on CentOS6.2. Today, we need to use CentOS again. For gcc, we only use the stricter open-source protocol GPL v3. The latest gcc version officially provided by CentOS can only reach 4.4, and new features must be used, you must manually compile the new version of
