sagemath 8.9 is not complied on macOS Catalina with python3

[Junwei Wang]

Besides, could the SAGE team officially release binary with Python 3 (although it is not stable), since we are force to use python3 in many cases and it is painful to compile by user themselves?

It's hit and miss for Sage to build on Catalina, I think the latest
Xcode cannot not build it.
Otherwise there is an option to use Conda, which allows you to select
Python3, as far as I know
(Isuru will correct me if I'm wrong...)

I have compiled it without any problems. You should not be using gcc from homebrew, but rather the version of gcc installed by Xcode or its command-line tools. That might help. (You should install the homebrew gcc package to get gfortran, but at least for me, installing homebrew's gcc installed /usr/local/bin/gcc-9, not /usr/local/bin/gcc. The presence of /usr/local/bin/gcc-9 is fine, the presence of /usr/local/bin/gcc is not.)

If I followed all this up correctly, on Catalina Xcode 11.0 works, but
Xcode 11.1 does not.
What Xcode version are you using?

If I am allowed to quote classics here:

Quo usque tandem abutere, Catalina, patientia nostra? Quam diu etiam
furor iste tuus nos eludet? Quem ad finem sese effrenata iactabit
audacia?

O tempora, o mores!

Xcode 11.1 does not.
What Xcode version are you using?

11.1. "xcode-select --version" says "xcode-select version 2370". "gcc --version" says

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/4.2.1
Apple clang version 11.0.0 (clang-1100.0.33.8)
Target: x86_64-apple-darwin19.0.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

I also have homebrew's gcc and gforfran installed. I downloaded homebrew when I had a beta version of Catalina, about a week before the actual Catalina release. Once Catalina was released, I did "brew uninstall gcc" and then "brew install gcc" to test it out, and it built gcc and gfortran from scratch. I then built Sage using that.

This is not on my main computer, so I didn't mind if things went wrong. I was pleasantly surprised that everything worked.

Yes, sage on conda-forge supports python 2.7, 3.6 and 3.7 on linux (glibc x86_64) and osx-64.
