Hi, everyone.

I am trying to get up and running with Kotlin/Native, using GLFW3, but I have a few questions and I find the pages on Github and KotlinLang a bit confusing.
I have already built the GLFW3 Source into .A files, which are located in ~/Downloads/glfw/src/libglfw.a
The example on gitchurn has this following def file:

headers = git2.h
linkerOpts.osx = -L/opt/local/lib -L/usr/local/lib -lgit2
linkerOpts.linux = -L/usr/lib64 -L/usr/lib/x86_64-linux-gnu -lgit2
headerFilter = git2/** git2.h

Why is this using .h files? And if I have .a files what reference should I follow to get it working?

[Hamza]

From what I have been able to gather, here is what I have gotten:
build.gradle: https://hastebin.com/ocuduwipid.gradle

def file:
path: src/cinterop/glfw3.def
file:

headers = glfw3.h
staticLibraries = libglfw3.a
libraryPaths = /Users/32350/Downloads/GLFW
compilerOpts = /Users/32350/Downloads/GLFW

that path: Downloads/GLFW:

C, unlike Java have separate binary artifacts (binary .a) and linking information (textual .h), so to generate Kotlin bindings (,klib) we need both.

Alright. I did aa lot of googling and reading and I got it working

[Hamza]

my header file looks like this:

package = glfw
headers = GLFW/glfw3.h
compilerOpts=-I/usr/local/include
linkerOpts= -lGLFW -L/usr/local/lib

, but im not sure what that -l and -I, and the -L means.

-I is the folder where .h files are searched for. The I stands for include.

Similarly the -L (that stands for library) indicates folders to search for libraries .a files in unix or .lib on windows. The -l lower case is for libraries too, but indicates the library to be loaded found in the specified folders.

When specifying -lGLFW it will search for a libGLFW.a file in /usr/local/lib in your case.
And in your case the the include would be loaded from /usr/local/include/GLFW/glfw3.h

i see. thanks for the clear explaination
