has anyone added a cinterop Obj C framework to a test execut kotlinlang #multiplatform

i managed to accomplish this by building both a dynamic and static framework, grabbing the headers from the dynamic framework, and throwing them in a directory with the static framework library

kind of kludgy, but whatever

We're looking at testing now as well. Can you post your build file to do what you described?

i'll post the relevant section, but it's only one piece of the puzzle

Copy code

iosX64("ios") {
        compilations {
            "main" {
                dependencies {
                    implementation("suparnatural-kotlin-multiplatform:fs-iosx64:$suparnaturalVersion")
                }
            }
            "test" {
                cinterops.create("OHHTTPStubs") {
                    includeDirs("c_interop/OHHTTPStubs/Headers")
                }
            }
        }
        binaries.getTest(DEBUG).linkerOpts("-Lc_interop/OHHTTPStubs")
    }

I’ve built a test framework in the past, but don’t currently have that wired up. If you pass “-tr” into the compiler it’ll generate a test runner. You can call that entry point from swift/objc, and it’ll run the tests.

You have to find the actual code entry point generated. It’s something related to this: https://github.com/JetBrains/kotlin-native/blob/c3b2b47403b6705e25ed6744615a0c93a21a153c/backend.native/compiler/ir/backend.native/src/org/jetbrains/kotlin/backend/konan/llvm/EntryPoint.kt#L51

Actually, looks like it’s this (or was). Had this in Droidcon app but dropped it: https://github.com/touchlab/DroidconKotlin/commit/8954a77734f70d7bbaec58e28fdba2275a37ae54#diff-79c332fa419905c2845cbbed041c9f91R11

to be clear, I just wanted to link my existing text executable (the default one) to an obj-c framework

it needs to be static
