Hey all, got this error when linking a C library to a Kotlin Native app:

> Task :linkDebugExecutableNativeLinuxX64

e: /home/runner/.konan/dependencies/x86_64-unknown-linux-gnu-gcc-8.3.0-glibc-2.19-kernel-4.9-2/x86_64-unknown-linux-gnu/bin/ld.gold invocation reported errors

Apparently, glibc bundled with Kotlin Native toolchain (2.19 in x86_64-unknown-linux-gnu-gcc-8.3.0-glibc-2.19-kernel-4.9-2) is of lower version than might be required (GLIBC_2.33 ).
Any clues on how to resolve that would be welcome. Thanks!

No idea how to sort it out, maybe somebody here knows off the top of their head, but if I were to investigate this myself, I'd start by adding freeCompilerArgs += listOf("-Xverbose-phases=Linker") to your build.gradle.kts to see what exact parameters the linker uses. Hopefully that'll give you more info what to try next.

Hey Jan, thanks for a suggestion, I tried it and also checked Gradle output with --info and --debug flags and got no extra info from linker. Also filed a Kotlin issue , maybe Kotlin team would know, let’s see.
