I built a shared library, according to the MSVC property manager it is a 32-bit DLL. Yet, when I do julia> lib = Libdl.dlopen("C:\\Users\\PetrKrysl\\Documents\\Work-in-progress\\H2Lib-community\\build\\Library\\Release\\H2LIB.dll") I get ERROR: could not load library "C:\Users\PetrKrysl\Documents…

My student, who solved the problem, will write a tutorial to the others students showing how he did it. As soon as he finishes, I will post the steps here!

So, is the issue that a 64-bit Julia cannot load a 32-bit shared library?

Thanks! Is that a general statement for any operating system? Clearly I can run 32-bit Julia on a 64-bit Windows 10… So isn’t that exe loading some Windows libs?

There was a similar thread recently where 32 vs 64 bit windows/Julia was an issue that may be a starting point. Can you give any more info on your build process?
