Getting an `Undefined symbols for architecture arm...

Getting an Undefined symbols for architecture arm64 during a KMM build (using sqldelight).
See 🧵 for full error log.

It seems similar to https://github.com/cashapp/sqldelight/issues/1442 but it’s not the same exact missing symbols.
What could this be? (perhaps related to: https://kotlinlang.slack.com/archives/C3PQML5NU/p1650038479860419)

[kpgalligan]

Same issue. Same resolution(s) https://github.com/cashapp/sqldelight/issues/1442#issuecomment-1048131450

[julioromano]

The -lsqlite3 linker flag didn’t solve it. I had to use isStatic = true in the gradle framework lambda.

[kpgalligan]

Well, it might be some kind of build cache issue, but the problem was definitely linking to the SQLite library. If you remove -lsqlite3 and confirm it's not added elsewhere, I'm sure you'll see that error again.

[julioromano]

I removed -lsqlite3 though I have no idea how to confirm if it’s added elsewhere, I’m a KMP noob.

[kpgalligan]

Generally "other linker args" in xcode. Somewhat different for cocoapods. It's less of a kmm thing than a general iOS thing

[julioromano]

Seems empty, maybe it can come from $(inherited) ?

[julioromano]

Btw… I’m not using the cocoapods plugin, going the “framework” way.

[kpgalligan]

Sqldelignt adds that link in the Gradle plugin unless you disable it (https://github.com/touchlab-lab/KaMPKit-encrypted/blob/main/shared/build.gradle.kts#L87). It's possible static carries that through and dynamic didn't, but somebody is for sure linking to SQLite.

[julioromano]

Weird… I must have run into some build caching issue.
I can now reliably reproduce that I can only get it to work with:
isStatic = true in the gradle config AND -lsqlite3 in xcode config.
Dynamic framework doesn’t work.

[kpgalligan]

Hmm. The dynamic not working is weird, but hard to comment without playing with the code.

[julioromano]

Agreed. Thanks a lot for your inputs.
