I thought Euphoria/Phix could only open DLLs made from C? Though being able to read DLLs from other languages could be possible.

hi,
it should be possible for x64!
I use a lot of dlls from fortran and pascal. GCC(MING) and FPC/Delphi use a different way of generating libs and dlls. That should definitely work in EU/Phix, but not because I use that. I would hate to write a layer for a FPC/Delphi/Fortran dlls in C/C++ to add additional time to and more code to something that should be easily possible. BTW i made a minimal layer for VS22, AWD Modula and PB to see if that DLL works correctly - it does. With Pelles tools, it is easily possible to generate libs and here also.

Probably 32/64 bit. Use demo/pGUI/filedump.exw to open the dll you made and check on the "PE Header" tab which it is.
Obviously you can also run p[w].exe without any params to see what that is as well.
Should it not be that simple, or filedump don't play nice with it, upload the dll somewhere and I'll have a bash at it.

Hi Pete, thanx for having a stab at it. this sounds stupid, but I am trying to port most of my stuff, that I use regulary, to be able to work with phix. I just love it.
Here the nums:

Doesn't seem to be anything wrong with that. If you upload the file (to eg Smash) and post a link here, I'll take a look.

That dll is dependent on fpcmemdll.dll which I don't have so can't ever open here.
Try and find that and put (the right 32/64 bit version) alongside wingraph12.dll - if it works, you'll have to
a) distribute it, and b) do something along the lines of demo/pGUI/win(32|64) that pGUI.e does, ie chdir()
to the appropriate subdirectory and back to a previously saved current_dir() around the open_dll(), or maybe
c) put a 64bit fpcmemdll.dll in Windows/System32 and a 32bit fpcmemdll.dll in Windows/SysWOW64 (yes, that way round), or
d) put (say) requires(64) at the top of your app/lib and that way force the issue so you only need one fpcmemdll.dll, or
e) do something with the path settings, probably best speak to someone on the fpc forums about that.
I just got 36 hits from google for "fpcmemdll.dll" and one of those might prove enlightening, not that I read any of them.

Hi Pete,
thanx for your hints and helps. Seams like, that fpc code as a DLL doesn't work with C or any other language as a dll, when being called - functions are exported, but are not callable. So now I am rewriting the whole shabang in C and that starts to work nicely. As soon as I have going for public consumption I'll post it with src. I am shooting for BGI with scrolling windows and full screen mode. The latter I have still to implement.
Please keep your good work comming -
you all have a nice, happy and prosperous new year
Richard
