    $ wget https://ftp.gnu.org/gnu/gdb/gdb-14.1.tar.gz

2. untar the tarball and cd

4. configure and complete

    $ ./configure --with-python=python --prefix=$(readlink -f build)
    $ make -j

* Maybe get the compile error.
* 
* `unset C_INCLUDE_PATH` to not include the /usr/include/unistd.h
* Maybe cannot find the python

        checking whether to use python... yes
        checking for python... /opt/python27/bin/python
        checking for python2.7... no
        configure: error: python is missing or unusable
