lpsolve distributed files

lpsolve is distributed as several separate archive files. It is most unlikely that you need them all for your purpose. This text describes each archive's contents.

There are two kind of archive files:

• ziped files (.zip)
• gziped tar files (.tar.gz)

Ziped files are basically binaries (executables/libraries) for the Windows platform.

gziped tar files can be divided into two categories:

• binaries (executables, libraries) for the Linux/Mac OSX platform.
• source files that are operating system independent.

lpsolve library

Most of the links from lpsolve to other software need the lpsolve library lpsolve55.dll (Windows) or lpsolve55.so (Unix/Linux/Mac). This library is in general not included in the archives. It must be installed separately. It is contained in archive lp_solve_5.5.2.11_dev_win*.zip (Windows) / lp_solve_5.5.2.11_dev_ux*.tar.gz (Linux) / lp_solve_5.5.2.11_dev_osx*.tar.gz
This library must be put in a path known by the system. That is:

Under Windows, the following search order is used:

1. Current directory.
2. A semi-colon-separated (;) list of directories in the user's PATH environment variable. windows\system32 is a common folder that is normally defined in this environment variable. This folder is a good place to put the dll.

Under Unix/Linux, following search order is used:

1. A colon-separated (:) list of directories in the user's LD_LIBRARY_PATH environment variable.
2. The list of libraries specified in /etc/ld.so.cache (which is generated from /etc/ld.so.conf).
3. /lib, followed by /usr/lib. Note the order here; this is the reverse of the order used by the old a.out loader. The old a.out loader, when loading a program, first searched /usr/lib, then /lib (see the man page ld.so(8)). This shouldn't normally matter, since a library should only be in one or the other directory (never both), and different libraries with the same name are a disaster waiting to happen.
