问题
I'm trying to use cocoapods framework in Kotlin Multiplatform project. So I
- added framework to Pods file.
- ran pod install.
- created
.def
file - added
cinterop
config inbuild.gradle
./gradlew cinteropFirebaseIos
runs successfully. It generates .klib
so I can see classes in kotlin code.
But when I'm trying to run iOS app build fails with message:
Showing Recent Messages
> Task :app:linkDebugFrameworkIos
ld: framework not found FirebaseDatabase
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ld invocation reported errors
Here is my config in build.gradle
fromPreset(presets.iosX64, 'ios') {
compilations.main {
outputKinds('FRAMEWORK')
cinterops {
firebase {
def proj = "${System.getProperty("user.home")}/Projects/kmpp"
def pods = "${proj}/iosApp/Pods"
defFile "${proj}/app/src/iosMain/c_interop/libfirebase.def"
includeDirs "${pods}/Firebase",
"${pods}/Firebase/CoreOnly/Sources",
"${pods}/FirebaseAnalytics/Frameworks/FirebaseAnalytics.framework/Headers"
}
}
}
}
here is my .def
file:
language = Objective-C
headers = /Users/oleg/Projects/klug/crckalculator/iosApp/Pods/FirebaseCore/Firebase/Core/Public/FIRApp.h /Users/oleg/Projects/klug/crckalculator/iosApp/Pods/FirebaseDatabase/Firebase/Database/Public/FIRDatabase.h /Users/oleg/Projects/klug/crckalculator/iosApp/Pods/FirebaseCore/Firebase/Core/Public/FirebaseCore.h
compilerOpts = -framework FirebaseDatabase
linkerOpts = -framework FirebaseDatabase
How can I figure out what is wrong ? Did I miss something in .def
file ? In build.gradle
?
回答1:
There are two problematic moments here:
- full paths to C headers in
.def
file are usually not desirable, instead passingincludeDirs
to Firebase installation, like in https://github.com/JetBrains/kotlin-native/blob/c7c566ce0f12221088a8908b6dc8e116c56a931b/samples/gtk/build.gradle#L22 would be helpful - linking problem comes from the similar issue - linker just got no idea where to look for framework libraries, so passing to
compilations.main.linkerOpts
smth like-F /Users/oleg/Projects/klug/crckalculator/iosApp/Pods/FirebaseCore/
shall help, see for example https://github.com/JetBrains/kotlin-native/blob/c7c566ce0f12221088a8908b6dc8e116c56a931b/samples/videoplayer/build.gradle#L15
