Hello How is decided whether the name of imported function gets the ending of the form @4 in ghc? I'm having this problem on Windows trying to use HSQL MySQL on windows. I compile HSQL Oracle backend and I get names without that. It's ok. With HSQL MySQL I get names with that stuff. It prevents me from further linking to dll. Supplying in the ghc command-line the "lib" file where names have those marks doesn't have any effect. The linker says that fname@NN cannot be resolved. Can I control that? The ffi calling convention doesn't (and shouldn't as I understand) affect this. The only difference is that in the case of mysql the header file itself where functions are described marks it STDCALL. Is that the reason? Also I changed ffi import line from "hsmysql.h func" to just "func", to no avail. ghc 6.8.2 I'm lost. Please help. -- Daniil Elovkov
