gccのversionを見てみます。

gcc version 4.4.7 20120313 (Red Hat 4.4.7-17) (GCC)

gcc-c++(g++)のversionを見てみます。

[root@localhost Desktop]# g++ -v

Using built-in specs.

Target: x86_64-redhat-linux

Thread model: posix

gcc version 4.4.7 20120313 (Red Hat 4.4.7-17) (GCC)

Matlab R2016bの対応コンパイラはgcc4.9.xです。

yum install gcc

だと4.4.7までしか対応しません。

そこで以下のホームページ

http://www.task-notes.com/entry/20151114/1447492231

を参考にgcc 4..29をインストールしてみました。

Devtoolset-2とDevtoolset-3をインストールします。Devtoolset-3はFedora用のを読み込んでいるためかエラーが出ますが、--no-check-certificateとすることでインストールできます。

Devtoolset-2のリポジトリのインストール
