2.报错二：

解决办法：

修改abseil-cpp/absl/synchronization/internal/graphcycles.cc文件，

添加 #include

configure: error: in `/home/wangkun/Desktop/swig-4.0.0':
configure: error: 
        Cannot find pcre-config script from PCRE (Perl Compatible Regular Expressions)
        library package. This dependency is needed for configure to complete,
        Either:
        - Install the PCRE developer package on your system (preferred approach).
        - Download the PCRE source tarball, build and install on your system
          as you would for any package built from source distribution.
        - Use the Tools/pcre-build.sh script to build PCRE just for SWIG to statically
          link against. Run 'Tools/pcre-build.sh --help' for instructions.
          (quite easy and does not require privileges to install PCRE on your system)
        - Use configure --without-pcre to disable regular expressions support in SWIG
          (not recommended).
See `config.log' for more details

(venv) wangkun@wangkun-virtual-machine:~/Desktop/swig-4.0.0$ ./configure --without-pcre

Could NOT find PythonLibs (missingPYTHON_LIBRARIES PYTHON_INCLUDE_DIRS) (Required is at least 3.5）
