No additional library is necessary.

Here is the procedure to install Primer3 from source code:

• The archive with the source code is downloaded from its website into /home/bioubuntu, decompressed and the resulting folder is moved into /opt/bio/sources.

• This folder should belong to root and its permissions should be set to 755.

% sudo chown -R root:root /opt/bio/sources/primer3-2.2.2-beta

• Once you are in primer3-2.2.2-beta, compilation is easily done:

% cd ./src
% sudo make && sudo make test

• To make sure that everyone can use it:

% sudo ln -s /opt/bio/sources/primer3-2.2.2-beta/src/primer3_core /usr/local/bin/primer3_core
