I'm Getting an Error From the Sentury Plugin on The Native Build

[alexwhb]

I'm using Kermit 1.1.3 with the co.touchlab:kermit-sentry plugin. Everything seems to work fine on Android, but on the native side it's not working properly. I've tried building for a real device as well and I get some other odd errors. It will sometimes build but then it gives

Here's what my error message looks like:

e: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ld invocation reported errors

The /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ld command returned non-zero exit code: 1.

Seems like maybe the Sentry arm64 binaries are not being built properly or something?

Sentry is an iOS dynamic framework - the code will be there at runtime - so the linker only needs to be told that to ignore the symbols for now (using the -U option). You can do that in gradle by passing linker flags to the kotlin native compilation for the symbols you mentioned -

freeCompilerArgs += listOf("-linker-options", "-U _OBJC_CLASS_\$_SentrySDK")

and

freeCompilerArgs += listOf("-linker-options", "-U _OBJC_CLASS_\$_SentryBreadcrumb")

(Note: the $ is being escaped with an extra \)
