Installing gcc-8 from http://pkg.loongnix.cn/loongnix/pool/main/g/gcc-8/

riple

昨天Wifi没配置好，先是dhcp，然后是dns的问题。就准备从PC上下载Nginx Directory (loongnix.cn)上gcc的deb包，通过网线scp拷贝到99Pi上，手动安装。
一通dpkg -i *.deb，结果一堆依赖没解决完，还把apt搞坏了。
现在解决了dhcp和dns的问题，发现apt不能用了，所有apt命令都报：
apt: error while loading shared libraries: libgcc_s.so.1: cannot open shared object file: No such file or directory


求高手指导，该如何修复该问题。

gcc-8 is successfully installed. But when I tried to compile a simple program, it reports:

1. root@LoongOS:work# gcc-8 hello.c
   
2. /usr/lib/gcc/loongarch64-linux-gnu/8/cc1: error while loading shared libraries: libisl.so.19: cannot open shared object file: No such file or directory

Another issue is that the Wifi configuration does not work any more:

1. root@LoongOS:~# wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf
   
2. wpa_supplicant: error while loading shared libraries: libgmp.so.10: cannot open shared object file: No such file or directory

针对这个问题，我在”意见和建议“里面回复了，可以试试看

Thank you so much!
All the above commands work now!

I added the variable as you suggested:

1. export LD_LIBRARY_PATH=/usr/lib/loongarch64-linux-gnu/
