GCC5.4 Installation

1. Download

Mirror site: https://gcc.gnu.org/mirrors.html

The speed is also good: ftp://ftp.mirrorservice.org/sites/sourceware.org/pub/gcc/releases/

2. Unzip the installation dependent library

./contrib/download_prerequisites

3. Configuration

./configure--disable-multilib (does not generate a cross-compiler compiled for executable code for other platforms)

4. Compiling the installation

Make && make install

5. Test code

#include <iostream> #include <string> #include <iterator> #include <algorithm> #include < array> int main () {    //Construction uses aggregate initialization    Std::array<int, 3> a1{{}};  Double-braces required    std::array<int, 3> a2 = {1, 2, 3};//except after =    std::array<std::string, 2& Gt A3 = {{std::string ("a"), "B"}};     Container operations is supported    Std::sort (A1.begin (), A1.end ());    Std::reverse_copy (A2.begin (), A2.end (),                       std::ostream_iterator<int> (Std::cout, ""));     Std::cout << ' \ n ';     Ranged for loop was supported for    (auto& s:a3)        std::cout << s << ';    Std::cout << ' \ n ';    }

　

If the following error occurs:

/usr/lib64/libstdc++.so.6:version ' glibcxx_3.4.21 ' not found (required by./test)

To update a soft connection:

/usr/lib64/libstdc++.so.6-/usr/lib64/libstdc++.so.6.0.21
