• What is Aldor?
  Answer: see the overview
   
  
• How can I get the Aldor compiler?
  Answer: The Aldor binary distributions of the compiler are available free of charge for non-commercial use. Please see the included license for more details.
   
  
• I want to report a problem with the compiler and/or libraries distribution, how do I proceed?
  Answer: Click here to send us an email.
   
  
• I want to report Aldor compiler bugs, how do I proceed?
  Answer: Use the aldorbug program (available in the distribution).
   
  
• Is there an Aldor developer mailing-list?
  Answer:Yes, there is. You can find it by following the Mailing lists link. If you want to post on that list, you have to subscribe first. We did that to reduce the amount of spam that we receive.
   
  
• How do I check out sources from CVS repository?
  Answer: First you need to setup the environment for cvs:
  export CVS_RSH=ssh
  export CVSROOT=:ext:your_username@cvs.aldor.org:/local/cvsroot
  (you can put these in ~/.bashrc)
  Now, you should be able to checkout all the sources from cvs, provided that you have an account on the cvs machine. To checkout the sources:
  mkdir $HOME/aldor_tree
  cd $HOME/aldor_tree
  cvs checkout aldor --> this will copy everything
  cvs checkout aldor/lib/algebra --> this will copy the algebra library
  cvs checkout aldor/lib/aldor --> this will copy the libaldor library
  Note: You will be asked to enter a password. The password is the same as the one from the SCL network.
  Now that you have the sources of the project, you can build them in the place of your choice.
   
  
• When I compile an Aldor source file, it doesn't find gcc32?
  Answer:Aldor compiler is not compatible with latest version of gcc (version 4). New linux distributions use version 4 of gcc as the default C compiler. If that is the case in your distribution, using gcc will not work. That is the reason we replaced gcc with gcc32 in aldor.conf. If you use an older Linux distribution you should comment those two lines from aldor.conf that contain gcc32. The current setting should work for Fedora Core 4 and 5, for other linux distributions find the name of the older C compiler and use that instead of gcc32.
   
  

A few tips ...

• Use functions
   
  Avoid writing programs with heavy computation at the top-level of a file (ie. not inside a function). The compiler performs little or no optimization on statements at the top-level at present. For example:

         #include "axllib"
  
         import from SingleInteger;
  
         for i in 1..10 repeat {
            for j in i..10 repeat {
              -- some calculation ...
            }
         }
  

  can be rewritten by enclosing it in a function and be optimised:

         #include "axllib"
  
         main():() == {
            import from SingleInteger;
  
            for i in 1..10 repeat {
               for j in i..10 repeat {
                  -- some calculation ...
               }
            }
         }
  
        main();
