Oolite Bulletins

I'm trying to build Oolite from source on macOS Catalina, in Xcode 11.4. I cloned the git repository, and following the instructions in readme.md I would only have to open the .Xcode project, and hit the run button to compile. What happens is that I get an error messages stating, correctly, that "Build input file cannot be found: '/Users/maik/Projects/oolite/oolite/deps/mozilla/nsprpub/pr/src/md/unix/uxproces.c' and so on. The directory ~/Projects/oolite/oolite/deps/mozilla/ does not contain anything indeed.

Am I missing some step?

Thank you, kind regards,

It's very likely you forgot to run "git submodule update --init" after your cloning command.

The Oolite source is available from github.
Use `git clone https://github.com/OoliteProject/oolite`
to retrieve. Then `git submodule update --init`
to fetch the various submodules.

You can quickly check this if any of the "deps" folders are populated.

Thank you, that helped, I did not look further down in the readme.md after the "Building" headline

Now I am running into an error with libstdc++ being deprecated though, in the build target jsoplengen, project libjs:

clang: warning: libstdc++ is deprecated; move to libc++ with a minimum deployment target of OS X 10.9 [-Wdeprecated]
ld: library not found for -lstdc++
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I guess this is due to using the latest Xcode, does someone know how to work around this without going back to an earlier version?

Yea, that sounds familiar.
My last OS X incursion (one and a half or two years ago) required some ... merciless adjustments, as far as I remember (and I don't remember what they were )
