Kotlin Multiplatform build fails on macOS

[JulianBissekkou]

I am pretty new to kmp, so I might be wrong here but I assume that the sqlite3 library on the mac is somehow "outdated" and does not contain the symbols.

I assume that the libary that is linked is a system library stored at /System/Library/Tcl/sqlite3/libtclsqlite3.dylib.
When I try to search for the first missing symbol I get no result:

nm /System/Library/Tcl/sqlite3/libtclsqlite3.dylib | grep load_extension  

However, when I do the same with sqllite installed by homebrew I get some results:

nm /opt/homebrew/Cellar/sqlite/3.42.0/lib/libsqlite3.dylib | grep load_extension
00000000000116b4 T _sqlite3_enable_load_extension
000000000001122c T _sqlite3_load_extension

Does anybody maybe know a workaround? This issue is currently blocking for us.

I haven't built a macos app with sqldelight personally (I wrote most of the driver, or at least the original version). The tests run fine with -lsqlite3 without specifying the library search path, so I assume it's using a sqlite3 library from Xcode tools. libtclsqlite3 kind of seems like it's specific to tcl, but I've never used it. I would guess you'll need to include your own sqlite implementation.

Since you're building with Xcode, the easy solution would probably be to grab and build sqlite source directly in Xcode, and drop -lsqlite3. To do that just for iOS, I assume you'll need some target slight-of-hand in Xcode config.

I compiled the sql lib from the mentioned sources and added the dylib file to the project. It was able to find some symbols but still failed to compile since some of them are unknown.
Since I am building just a small POC i want to keep things simple. I was wondering if anything else is configued on my side.
Is there an example project with a macOS app that I can try out and compare?

@kpgalligan
If you run the tests are you compiling an MacosArm64 binary?
