Installation of p7zip

First, prevent p7zip from installing compressed manual pages: 

sed '/^gzip/d' -i install.sh

Next, fix a security vulnerability: 

sed -i '160a if(_buffer == nullptr || _size == _pos) return E_FAIL;' CPP/7zip/Common/StreamObjects.cpp

Install p7zip by running the following commands: 

make all3

To test the results, issue: make test.

Now, as the root user: 

make DEST_HOME=/usr \
     DEST_MAN=/usr/share/man \
     DEST_SHARE_DOC=/usr/share/doc/p7zip-17.04 install
[Note]

Note

If using DESTDIR techniques, use DEST_DIR instead.
