在centos 7上，我试图通过源代码安装GCC 5.4，但它总是进入无限循环。
环境：-
uname -a
Linux 3.10.0-1062.12.1.rt56.1042.el7.x86_64 #1 SMP PREEMPT RT Wed Feb 5 10:31:05 CET 2020 x86_64 x86_64 x86_64 GNU/Linux
cat /etc/redhat-release
CentOS Linux release 7.8.2003 (Core)
rpm -qa | grep -i gcc
libgcc-4.8.5-44.el7.x86_64
gcc-c++-4.8.5-44.el7.x86_64
gcc-gfortran-4.8.5-44.el7.x86_64
gcc-4.8.5-44.el7.x86_64
gcc --version

现在，我尝试构建GCC 5.4，并在无限循环中在屏幕上获得以下消息。

任何安装GCC的建议都会有很大帮助。
感谢您的指导。我尝试了更高版本的GCC 7.0，在服务器上启用互联网并运行"/contrib/download_prereprecisions"；。它解决了问题，GCC安装成功。
