error while loading shared libraries: libmpfr.so.6

问题描述

系统：The system is: Linux - 4.9.76-1-MANJARO - x86_64


今天是在用cmake配置库时候出现了这个问题，我以为是库的问题，但找了一个cmake测试程序
我发现并不是库出现了问题，而是在cmake执行的时候出现了问题，错误信息保存在如下两个文件里面：

Compiling the C compiler identification source file “CMakeCCompilerId.c” failed.
Compiler: /bin/cc
Build flags:
Id flags:
The output was:
1
/usr/lib/gcc/x86_64-pc-linux-gnu/7.3.1/cc1:

error while loadin g shared libraries: libmpfr.so.6: cannot open shared object file: No such file or directory

解决方法

参考

renhaofan@renhaofan-pc ~> sudo pacman -S mpfr
renhaofan@renhaofan-pc ~> ls /usr/lib | grep libmpfr
libmpfr.so
libmpfr.so.6
libmpfr.so.6.0.1
renhaofan@renhaofan-pc ~/t/b/CMakeFiles> sudo ln -s -f /usr/lib/libmpfr.so.6 /usr/lib/libmpfr.so.4

再次cmake

[renhaofan@renhaofan-pc build]$ sudo cmake ..
