The company requires that some tests be carried out under the CentOS6.5 system. Since some of the new features of c++11 are used in the written test program, and the GCC version installed in CentOS6.5 is 4.4.7, does not support c++11, so you need to upgrade GCC, note the upgrade process, this upgrade process requires the use of root permissions, Therefore, the installation needs to switch to the root user.1
Reprinted from: http://blog.sina.com.cn/s/blog_627b3f930101hnz8.htmlThanks a lot, Trig_yao .The CentOS6.5 comes with a gcc version of 4.4.7, some years, some new software to use the library did not, the latest GCC 4.8.2 has been released, so download the source code installed a try.1.

I. StatementAlthough most of Linux's core code is written in C language, some of them are inevitably written in assembly language. Some assembly language code is directly written in the Assembly source program, especially the Linux Startup code. Others are embedded in the C language program using the GCC embedded assembly language. This article briefly introduces the Embedded Assembly Language in GCC. It ma

CentOS 6.6 GCC upgrade After installing Matlab yesterday, DPM compile reports an error. The following error indicates that c ++ 11g ++ is supported. However, the default gcc version of CentOS6 is 4.4.7, and the version supporting c ++ 11 is 4.8.0 or above (not sure here )? Therefore, you need to manually update GCC here.

I. Statement Although most of Linux's core code is written in C language, but the inevitable part of it is written in assembly language. Some assembly language code is written directly in the assembly source program, especially the Linux boot code section, and some of the use of GCC embedded assembly language embedded in the C language program. This article briefly introduces the embedded assembly language in GCC

First describe the error you encountered today:Because before writing the program, write is CPP file, and then directly use g++ compile, no error, also did not care about these problems, today there is a C file, but contains after the STL vector syntax, think of using GCC to compile, the result error, error is: Can't find the vector.What is gcc/g++First of all: GCC
Currently, the most common C language compiler in Linux is GCC (GNU Compiler Collection ). The ansi c standard compilation system can compile programs written in C, C ++, Object C, and other languages. GCC is not only very functional Powerful and flexible in structure. The most commendable aspect is that it supports various languages through different front-end modules. Such as Java, Fortran, Pascal, Modula
