Question

我有一个简短的C ++代码，我已在远程服务器A上成功编译。我希望在另一个目标远程服务器T上运行可执行文件。

代码main.cpp包含以下代码段（需要C ++ 11支持）：

#include <random>
default_random_engine GENERATOR;
void get_random_indices(set<int> &output, int max_ind) {
    uniform_int_distribution<int> dist(0, max_ind);

    while (output.size() < SAMPLE_SIZE) {
        output.insert(dist(GENERATOR));
    }
}

我使用以下行编译代码：

g++ -o exec_foo -std=c++11 main.cpp

服务器A的规范是

[me@A ~]$ uname -a
Linux some-ip:D 2.6.32-573.1.1.el6.x86_64 #1 SMP Tue Jul 14 02:46:51 EDT 2015 x86_64 x86_64 x86_64 GNU/Linux

[me@A ~]$ g++ -v
Using built-in specs.
COLLECT_GCC=g++
COLLECT_LTO_WRAPPER=/nfs/nfs5-insecure/home/insecure-ro/software/rhel6_x86_64/gcc-5.1.0/bin/../libexec/gcc/x86_64-unknown-linux-gnu/5.1.0/lto-wrapper
Target: x86_64-unknown-linux-gnu
Configured with: ./configure --prefix=/l/gcc-5.1.0
Thread model: posix
gcc version 5.1.0 (GCC)

当我在服务器exec_foo中运行A时，它运行正常。现在，在目标服务器T上运行相同的可执行文件会导致以下错误：

./exec_foo: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.18' not found (required by ./exec_foo)
./exec_foo: /usr/lib64/libstdc++.so.6: version `CXXABI_1.3.5' not found (required by ./exec_foo)
./exec_foo: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by ./exec_foo)

检查目标服务器T上的规范，我看到以下内容：

-bash-4.1$ uname -a

好的，我明白了。服务器T找不到库的某些链接。但是我无法在T上本地编译代码：

-bash-4.1$ g++ -o exec_foo --std=c++11 main.cpp 
cc1plus: error: unrecognized command line option "-std=c++11"

否c++11。我们试试c++0x。

-bash-4.1$ g++ -o exec_foo --std=c++0x main.cpp 
main.cpp:64: error: ‘default_random_engine’ does not name a type
main.cpp: In function ‘void get_random_indices(std::set<int, std::less<int>, std::allocator<int> >&, int)’:
main.cpp:66: error: ‘uniform_int_distribution’ was not declared in this scope
main.cpp:66: error: expected primary-expression before ‘int’
main.cpp:66: error: expected ‘;’ before ‘int’
main.cpp:69: error: ‘GENERATOR’ was not declared in this scope
main.cpp:69: error: ‘dist’ was not declared in this scope

除了更新我无权做的服务器g++上的血腥gcc + T之外，还有出路吗？

许多人提前感谢，并嫁给圣诞节。
