Hello,
I have the following directories set : Project/ Project/Language Project/Language/Copilot/ in Project there is the copilot.cabal file. in Project/Language/Copilot there are a bunch of .hs files, including Main.hs All the modules in these files are named Language.Copilot.NameOfTheFile for cabal to work.
My issue happened when I chose to add a Main.hs, containing Language.Copilot.Main and to try to compile it with ghc --make. I got the error message "output was redirected with -o, but no output will be generated because there is no Main module." So I replaced Language.Copilot.Main by Main. ghc was happy, but cabal sent me the following error message : "File name does not match module name: Saw: `Main' Expected: `Language.Copilot.Main'" So I finally kept the Language.Copilot.Main module name, and tried to use the -main-is ghc option. The result was an unreadable linker error message : "/usr/lib/ghc-6.12.1/libHSrtsmain.a(Main.o): In function `main': (.text+0x10): undefined reference to `ZCMain_main_closure' /usr/lib/ghc-6.12.1/libHSrtsmain.a(Main.o): In function `main': (.text+0x18): undefined reference to `__stginit_ZCMain' collect2: ld returned 1 exit status"
Does anyone know what this last message mean, and how to make both cabal and ghc happy with my module name ?
Why not just have a Main.hs file? As for that error message, do you have a main function? Are you sure you were using --make? -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
