I tried to load Libre Pilot and I assume my OS is not supported. Is there another way I can load and run it? Perhaps the Terminal?

I don't do Mac, but a wild guess is that you could try installing the standard C++ compiler.  Is that called "XCode"?  I found this by Googling:
libc++.1.dylib
There I also saw instructions for building libc++.1.dylib from source.

Or if it is a version issue, you could try hacking a link from whatever version is there (like libc++.6.dylib) to the requested version.

It probably won't work, but it may be worth a try.

Good advice. I have XCode on this Mac. Thank you.

Apparently libc++ is part of clang that was introduced into macOS in later versions.

The main "problem" here is that Qt distribution is also compiled with clang and it really needs it, so to avoid this lib, you'd need not only to build GCS on your own, but Qt as well.

My suggestion would be to first figure out how to bring clang to 10.6

I've got another younger mac stored away that I'm sure has a compatible OS for LibrePilot. If not I can load one on it to run it.

I'm afraid to tinker with the Snow Leopard OS.

I guess this documents where LibrePilot won't run easily. Thank you for the confirmation and details.

Hope the mac is in the first box in the store room. And it boots up.
