Tarballs (.tar.gz) of the source code for lqns. See the README files for build instructions (./configure; make; make install). For Windows, use MingGW64 (and use the 32-bit version of msys).

To build, you require the following programs/packages which may not be installed by default on Linux/MinGW/FreeBSD/... flex, bison, gcc-c++, expat-devel (header files are necessary), automake, libtool, groff (man pages) gd-devel (optional for png/jpeg output), texlive (optional for documentation), texlive-epsf (optional for documentation), fig2dev (optional for documentation).

On Redhat (Fedora, Centos,...), use "dnf install {program}". On Ubuntu, use "apt-get install {program}". On MinGW, use "pacman install {program}". On MacOS, use "port install {program}", or fink ???, or brew ????
