These installation instructions are directed primarily towards users operating in a unix/linux environment. Macintosh (system X) users should also be able to install the program. Windows users are on their own; at the very least, they need to install a C++ compiler (say GNU gcc), and GNU make (if that is possible at all) or an equivalent.
The software is provided in the form of a compressed tarfile. Saying "tar xzf name_of_tarfile" will create a directory called "atlas_version-number". You should then descend into that directory and say "make"; this should create an executable named "atlas", in that same directory. Depending on your path configuration, you launch the program by typing "atlas" or "./atlas".
The makefile calls the g++ compiler by default; if this is not available on your system, you should edit the makefile and replace it by the C++ compiler that you have. I will be interested to hear how the program fares with other compilers---but unfortunately I cannot promise any help with compilation problems (unless they originate from obvious bugs in the program.) The program has successfully compiled and run in the following environments:
The Intel compiler is very fussy, and with the very verbose compilation flags that are set by default (-Wall), it will drown you in "remarks". More seriously, it does not compile the headers for the GNU readline library, at least on my system. Therefore it is recommended to suppress the -Wall flags, and to compile with "make readline=false" (see below).
The program is known to not compile in the following environments:
