gdb 7.8 目前在trusty repo 中不可用。但是您可以从源代码安装它。
打开终端并输入以下命令
wget http://ftp.gnu.org/gnu/gdb/gdb-7.8.tar.xz
tar -xf gdb-7.8.tar.xz
cd gdb-7.8/
./configure
make
sudo cp gdb/gdb /usr/local/bin/gdb
它将安装gdb在/usr/local/bin/目录中。正如/usr/local/bin/之前搜索过的，/usr/bin/无论何时执行命令， runninggdb都会执行gdb 7.8。
安装后，您可以使用检查 gdb 版本
gdb --version
它应该输出
