I have created multiplatform library with some cinterop libraries for linuxArm64 and linuxX64. I published the library to my local maven repo. Now when i try to use the library in some project on linuxX64 the build goes fine, but when i try to compile for linuxArm64 i get cannot find -l<library name> and bunch of undefined reference to <something> . The library has def file with different linker paths for each architecture and build of the library goes fine for all build targets. The problem is only when i try to use the published library. So i am wondering what might be wrong here ?

So i found out that the .so files must be on the same path as defined in the .def in the library even in the project that uses the library. Is there a way to package the library with the .so files it uses? I want to just add the library in the gradle and for it to work. So i dont have to worry about having all the .so files in the correct path

Best practice for setting linking options is to do it on the Kotlin Native program side. A Kotlin Native library shouldn't be specifying linking options in order to be portable across platforms. Linking options can vary between Linux distributions.

Alternatively static library files can be packaged with a Kotlin Native library, which has the big advantage of having all linking managed on the library side, instead of dealing with it on the program side.

@napperley what do i have to do to package the static library files with the kotlin native library ?

[napperley]

Specify the linking information in the def file, and put all static libraries in a directory that is inside the project (eg c_libs). Below is an example def file (based on this Kotlin Issue - https://youtrack.jetbrains.com/issue/KT-24649/Kotlin-Native-an-option-to-include-static-dynamic-library-into-klib#focus=Comments-27-2909933.0-0):

staticLibraries = libui.a
libraryPaths = c_libs
