Building Java for Windows

[duane701]

How do I compile so that I can use the library to run a program on Windows?

The primary error is

No C compiler for Binary (shared library 'pathfinder:any64:sharedlibrary') with Toolchain clang on Platform any64. Skipping build.

Does the build require clang? I installed msys so that I have gcc.

What are the requirements and instructions for building the library so that I can build and run a program on Windows?

Thanks

On windows, you need to have Visual Studio installed in order to build native libraries with Gradle

[duane701]

I've now installed visual studio (I'll have to work out which installer I ran if it's important).

After building I get LINK: fatal error LNK1104: cannot open file 'kernel32.lib'

The error is from Pathfinder-Core:linkPathfinderAny64SharedLibrary.

The program we have developed uses Java which of course uses the shared library to run.

I'm on a 64-bit system.

Thoughts?

This sounds like a problem during installation. Check that you've installed the windows desktop C++ SDK, and that you did indeed install the 64 bit version.

same same 👎

I installed Visual Studio Community 2017 with "Desktop development with C++" and "Universal Windows Platform Development".

I've tried using the command prompt from "Developer Command Prompt for VS 2017" and "x64 Native Tools Command Prompt for VS 2017". Same error under both conditions.

Thanks for any tips.

(I'm not a Windows person. The library works great on the Mac.)

It sounds like other people are able to compile Pathfinder-Tool on Windows. I would appreciate any tips that might help me work out where I am running into a problem.

C:\Program Files (x86)\Windows Kits\10\bin\Lib\winv6.3\um\x64 does not exist, starting at Lib\winv6.3\um\x64. That is there is no Lib directory at all.

• How is this directory supposed to be installed?
• Does Gradle need to be updated?
• Are there options to set for Gradle?

Thanks

The correct path seems to be C:\Program Files (x86)\Windows Kits\10\Lib\10.0.16299.0\ucrt\x64 at least that's where kernel32.lib is located.

Why is gradle searching in this other location?

[dkt01]

I was able to build in Windows 10 with the Visual Studio 2017 build tools, but I had to download an additional Windows 10 SDK version using the installer. For some reason the default SDK wouldn't link correctly. Think it was the version just before the latest SDK version that worked correctly.

I was able to build in Windows 7 with the Visual Studio 2015 build tools, with default settings.

Gradle discovers the directory for VS based on the installation of vswhere with VS2017, since Gradle 4.4. That may be pointing to the wrong location. Can you run vswhere manually?

I tried on another computer (control variables) with the same result. Following @dkt01, I installed the additional SDKs one at a time. The requirement appears to be "Windows 10 SDK (10.0.14393.0)" in order get linking to work correctly.

Now that the library is compiled, I'll see if I can run the app.

[duane701]

My app compiled and executed. Closing this issue.

Thanks for looking into it, it's a particularly hard issue to reproduce. Glad you found the dep required
