Failed to Install z3-solver

Symptom

The z3-solver installation failed.

Key Process and Cause Analysis

To a large extent, the GCC version and CMake version are too early (CMake 3.4 or later is required). Therefore, you need to upgrade GCC and CMake.

Conclusion and Solution

The following describes how to upgrade to GCC 7.3.0 and CMake 3.13.4.

1. Upgrade GCC.
   1. Refer to the following document: https://www.hikunpeng.com/document/detail/en/kunpengcpfs/ecosystemEnable/OpenStack/kunpengopenstack_05_0017.html
   2. After the upgrade is complete, add environment variables.

      1 2	export LD_LIBRARY_PATH=/usr/local/mpc-1.0.3/lib:/usr/local/gmp-6.1.2/lib:/usr/local/mpfr-3.1.5/lib:/usr/local/gcc-7.3.0/lib64:/usr/local/isl-0.18/lib:/usr/local/lib:/usr/lib:$LD_LIBRARY_PATH export PATH=/usr/local/gcc-7.3.0/bin:$PATH

2. Upgrade CMake.
   1. Download the CMake installation package.

      1	wget https://github.com/Kitware/CMake/archive/refs/tags/v3.13.4.tar.gz --no-check-certificate

   2. Decompress the package, go to the directory, and run the following commands:
