This is now no longer a problem with the lib but my own problem that I would like to solve for future reference. When linking with the original dll it compiles and links just fine

[msink]

Don't know how you compile, but typical extension for static lib compiled by msys2-mingw64 is .a, not .lib.
See https://github.com/msink/kotlin-libui/blob/master/libui/src/nativeInterop/cinterop/libui.def#L5

I'm using a shared library. I only followed the kn docs and the libs build instructions here: https://github.com/signal11/hidapi

[alexcouch]

The kln docs say that all libs, even static libs, on windows need to be .lib

[msink]

You mean "To build HIDAPI using MinGW or Cygwin using Autotools, use the instructions
in the section titled "Building HIDAPI into a shared library on Unix
Platforms" above."?
Ok, cloned to f:\src, then in msys2-mingw64 console:

cd /f/src/hidapi
./bootstrap
./configure
make
make install

Got libhidapi.a and libhidapi.dll.a in msys64\mingw64\lib directory.

[alexcouch]

Yeah that's actually where I get stuck I guess. Not sure how to run those scripts on windows

[alexcouch]

But I'll take that question elsewhere since this is a kotlin native channel not a HIDAPI channel

[msink]

Well - if as you said K/N documentation mentiod somewhere that libs on Windows should be .lib - it's K/N documentation bug.

[alexcouch]

Yeah that is also true. It says all libs, static or dynamic, should be of .lib

[svyatoslav.scherbina]

What does compiler error look like? Could you share it?

[alexcouch]

And the .lib is also in the same location as my .exe output

[msink]

If you compiled by MSVC - of cource K/N don't see it.

[alexcouch]

Yeah that's what I was thinking actually. I'm still pretty new to the whole compilers and linker stuff. But I'll figure it out at some point.
