This is the download directory of GSL Shell. In order to compile GSL shell you need to download: - the last tarball with the source code of GSL shell, for example gsl-shell-v0.4.tgz - the source code of Lua patched with LNUM and configured to support complex number. For simplicity this file is directly available in this directory, it is the file: lua-5.1.4-lnum-gslshell.tgz The file with Lua shoud be extracted into the gsl-shell source folder. Then you should build Lua before. Normally this can be done like that: - enter in the lua-5.1.4 folder - type 'make linux' on linux or 'make mingw' on windows then GSL shell can be build by simplify typing 'make' The author can be contacted at the follow address: gslshell@gmail.com Francesco Abbate
