cole library version 2.0.1 (which can be downloaded from cole web site), and libxml library version 1.4.0 (which can be downloaded from libxml archive or Daniel Veillard ftp area).
Both cole and libxml must be compiled, installed and accessible before configure xls2xml. This means two things in particular: FIXME
cole-config and xml-config scripts must be executable in any place. This can be done by adding the paths where they are located in the enviroment variable PATH.
A program dynamically linked with cole and libxml must run. This is true if both libraries where installed in standard places in the system, if not you can add the path where they are located in the enviroment variable LD_LIBRARY_PATH.
The programs that uses the library xls2xml needs to be linked with cole and libxml, either static or dinamically.
