2745 :: 2 question about DLL with Mingw

• oyster (orginal) [2017-01-23T12:10:39+01:00] view original

  I have met this page: http://stackoverflow.com/questions/37950722/load-function-in-nim-dll

  I have 2 question for my MingW on windows:

  1. what can we do with Mingw? "#pragma comment(linker, "/export:double=_double")" produces only _double( that is to say there is no double) in the DLL
  2. Can we delete the NimMain in foo.dll?

  proc double(x: cint): cint {.cdecl, dynlib: "foo.dll", importc:"_double".}

  NimMain need to be called to initialize the gc, why you need to remove it?

  NimMain don't need to be called, because all GC initialization procedures can reside in DllMain() function, so there no reason to export NimMain.
