You can have several Main modules in the same directory if you don't use -odir. If you do use -odir, then you need to use a different value for -odir for each different program. Alternatively use -main-is, as Bulat suggested (actually this is better, IMO).

Can you tell us how to repeat the behaviour you're seeing? We aren't seeing any unecessary recompilation here. Like Wolfram Kahl, I am using -ddump-minimal-imports. I cannot check whether the use of this option causes the problem, because I returned to 6.2 already to continue porting my project from ghc 5. 6.2 and up: The object file is named after the module, not after the source file as in 5.04.

Hello Michael, Tuesday, November 22, 2005, 8:18:24 PM, you wrote: MM 6.2 and up: The object file is named after the module, not after the MM source file as in 5.04. As there are several main modules in my MM project, each in its own source file, all I get is a big mess. Any MM suggestions? you can give different module names to this modules and use -main-is option to specify main module in each compilation (see .../ghc/doc/html/users_guide/flag-reference.html) -- Best regards, Bulatmailto:[EMAIL PROTECTED] ___ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
