Hi folks,
First post ever. I'm attempting to compile the Genann neural network library into a DLL for import into newLISP.
https://github.com/codeplea/genann
I updated the C source and its header to comply with either STDCALL or CDECL conventions (tried both with no success). I tried several methods to output a DLL out of the C source, which all work fine except when importing in newLISP. The methods I tried are described here :
https://www.transmissionzero.co.uk/computing/building-dlls-with-mingw/
I checked the exports using Dependency Walker, and all functions are exported correctly (at least when using CDECL, somehow the STDCALL one still showed up as a C export.
No matter what I do newLISP returns the usual import error when attempting to import the DLL :
ERR: problem loading library in function import : "genann.dll"
My import line :
(import "genann.dll" "genann_init") (when stdcall)
or
(import "genann.dll" "genann_init" "cdecl")
I tried using the absolute path (with slashes) to the DLL, as well as both calling conventions, to no avail.
I tried compiling the DLL both with gcc straight to DLL (-shared etc.) and through mingw's dllwrapper, to the same result. The DLL file I'm getting seems legit, and I have no problem importing it from C.
Has anybody encountered this problem?
Thanks in advance!

I figured it out. Lutz pointed out I was using the 32 bits version of MingW, with the 64 bits version of newLISP. All I had to do is :
1) install MingW64
2) compile the genann source with:
gcc -m64 genann.c -shared -o genann.dll
Cheers,
Dexter
