I have written a plugin for the commercial statistical software Stata that bridges to Julia in order to exploit its speed. In an issue thread on juliaup , @davidanthoff and @staticfloat have helped me figure out how best to do this. But I’m still getting crashes on some Windows systems and am stuck. …

I think I solved it for my case! This substitutes for the LoadLibraryA() call in my example: SetCurrentDirectoryA(libdir); hDLL = LoadLibraryExA(fulllibpath, NULL, LOAD_WITH_ALTERED_SEARCH_PATH); where libdir is the path to the /bin folder and fulllibpath is that + “libjulia.dll”. I thin…

The first question to answer is whether Windows actually cannot find “libpcre2-8.dll” or if there anorher problem, perhaps with dependencies. You will then want to use gflags and a Windows debugger as described here: Debugging DLL Loading Errors How to debug MSYS2/MinGW64/Cygwin/GTK/et…

Essentially we will want the Debugging Tools for Windows: [image] Debugging Tools for Windows - Windows drivers This page provides downloads for the Windows Debugging tools, such as WinDbg. Then we will need gflags, the global flags editor. [image] …

Thanks @mkitti . Yes, libpcre2-8.dll is in my Julia bin folder, next to julia.exe and all the other dll’s. I should have mentioned that. I’ve already run it in the Visual Studio debugger. The error in Visual Studio is Exception thrown at 0x0000000000000000 in Project1.exe: 0xC0000005: Access violat…

Could the problem also be related to different C runtime libraries? I believe Julia uses msvcrt.dll (which is the very old version of it that ships as part of Windows for backwards compat reasons that MS would really like everyone to not use), but Visual Studio presumably would use more modern versi…

I’m unclear if you used gflags or not and what the error has to fo with the stacktrace. Did you try to continue execution past the “access violation”? Here is how the DLL search order works on Windows: [image] Dynamic-link library search order - Win32 apps You can control the specific …

[image] mkitti: Here is how the DLL search order works on Windows: Right. I believe that when Julia is installed with juliaup, the Julia dll’s appear nowhere in the list of places that Windows checks.

Set the gflags like I suggested above and then the debugger will tell you exactly where Windows is looking for libraries or why it cannot load anything.

This error is also raised when one tries to bundle Julia in a MSIX bundle for which I oppened #52007 issue. From what I skimmed through the solution seems to be recompiling julia and all it’s libraries with /ZW flag.

Not exactly answering your question but given what you’re doing you may find GitHub - GunnarFarneback/DynamicallyLoadedEmbedding.jl: Embed Julia with dynamical loading of libjulia at runtime. interesting, if you’re not already familiar with it. (I should add some documentation about juliaup there, …
