buildroot_initramfs/host/bin/riscv-nuclei-linux-gnu-gdb: error while loading shared libraries: libgmp.so.3: cannot open shared object file: No such file or directory

[fanghuaqi]

先按照文档按照了需要的软件，参见README.md

通过如下命令可以查看缺少的库

然后执行如下命令

$ ls -l /lib/x86_64-linux-gnu/libgmp.so*
lrwxrwxrwx 1 root root     16 Feb 24  2020 /lib/x86_64-linux-gnu/libgmp.so -> libgmp.so.10.4.0
lrwxrwxrwx 1 root root     16 Feb 24  2020 /lib/x86_64-linux-gnu/libgmp.so.10 -> libgmp.so.10.4.0
-rw-r--r-- 1 root root 534880 Feb 24  2020 /lib/x86_64-linux-gnu/libgmp.so.10.4.0
# 手动创建一个软链接到新版本的libgmp.so上，需要root权限
$ sudo ln -s /lib/x86_64-linux-gnu/libgmp.so /lib/x86_64-linux-gnu/libgmp.so.3

如下是正常链接的结果
