[Alexandre Bianchi]

Hi guys! How are you?
I did Jetbrains guide to create a Compose Multiplatform project, it worked.
I want also to integrate to Firebase Firestore, so there is the library https://github.com/GitLiveApp/firebase-kotlin-sdk, which intends to do this bridge to Firebase services for Compose Multiplatform.
The automatization from Jetbrains creates a project with only one folder composeApp, and inside of it we have all targets: Android, iOS, Desktop, Web, ...
When I add the libraries from https://github.com/GitLiveApp/firebase-kotlin-sdk inside commonMain sourceSet in build.gradle.kts(:composeApp) like below, and sync the project, it's creating the following errors (The full text of the errors in the thread).
I'm not understanding yet the reason since the library suppose to work with all targets.
Can you help?

            }
        }
        binaries.executable()
    }

        compilations.all {
            kotlinOptions {
                jvmTarget = "1.8"

        }
    }

There is no WASM target in the library.

[Chrimaeon]

You can only have Android, iOS, JVM and JS in your common target.

[Alexandre Bianchi]

Hi Christian. This wasm comes from official automatic template from Jetbrains.

[Alexandre Bianchi]

The new version. So this part I didn't change.

[Alexandre Bianchi]

It seems it is an error that Firebase library I said is not compatible, I don't know.

[Chrimaeon]

Yes, remove it or find another library.

[Alexandre Bianchi]

Hum!!

[Alexandre Bianchi]

Thank you Christian, it worked.
Sometimes we don't see what is in our screen. : )

[Alexandre Bianchi]

Hi @Chrimaeon, do you know if I can use Firebase.initialize for Desktop? It said we can't use context from ApplicationScope from Desktop.

[Alexandre Bianchi]

It seems is just for Android only, but strange because the lib says it's for every target.

[Chrimaeon]

looks like jvm is just using the andorid target

getByName("jvmMain") {
            kotlin.srcDir("src/androidMain/kotlin")
        }

and there is not “Android Context” on plain JVM. So, no, you cannot use this “constructor” on jvm.

[Alexandre Bianchi]

Understood, thank you

[Alexandre Bianchi]

It's said that they said it's possible to use for all targets.

[Chrimaeon]

yeah, no. where do you get the context from on your “common” code?

[Chrimaeon]

[Chrimaeon]

the Any parameter is casted to Context so it will not be possible to use it for JVM
