Unable to build from command line

[jerekapyaho]

Using Xcode 14.2 in macOS Monterey 12.6.4, I can build the LispKitREPL scheme just fine, but building from command line fails.

There are a couple of dozen errors, and they all seem to be related to availability of APIs.

Example of the output from make repl in Terminal, after the dependencies have been fetched and built:

...and so on. make clean does not change the situation.

It almost looks like I was on macOS 10.14 or older, but this is Monterey with the latest security updates as of 2023-03-29. Latest repository updates from master are included (commit 506e9199f5a295a934c7463b49bd0add31d39869)

I can't see anything obviously wrong with my Xcode installation, since the LispKitREPL scheme and also other macOS and iOS applications can be built. It's just the command line that is failing. Any idea what might be causing this?

Additional information: the command line build also fails in the same way in macOS Ventura 13.3 (with Xcode 14.2 installed, and Xcode command line tools just updated).

Thanks for the detailed bug report. Package.swift wasn't correctly updated wrt. minimum platform requirements, which is now macOS 11. Recently, a crypto library was added to LispKit and that pushed up the platform requirements to macOS 11. I've fixed Package.swift. Would be great if you could retry building the framework.

Thanks for fixing this! After pulling the latest change to Package.swift, the command line build make repl succeeds as expected. I was also able to execute the tests from the command line with make test. Awesome!
