FWIW, I built sage 8.9 on 10.14.6 without problems, and sage’s gcc was not built. I have Xcode 10.2.1 installed, and gcc tells me that it’s

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include/c++/4.2.1
Apple LLVM version 10.0.1 (clang-1001.0.46.4)
Target: x86_64-apple-darwin18.7.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

The fact that the installation is trying to build gcc means that either you don’t have it installed, or it’s way out of date. I think gcc 7.4 is way old for macOS 10.14.

You could try installing the command-line tools for Xcode 10.2.1 and see what happens.

Unless there is a strong reason to build SageMath 8.9,

I would advise to build SageMath 9.0 or even 9.1.rc4.

On macOS the absolute prerequisite is to install

Apple's Command Line Tools for Developers. Installing

the full Xcode can be done too but is not required.

One can additionally install Homebrew. Many packages

needed by Sage can then be installed precompiled via

Homebrew. This can decrease SageMath's build time by

a fair amount.

To install Homebrew follow the instructions at

    https://brew.sh/

Then after getting and extracting the SageMath sources,

change to the extracted SageMath directory, and run

    $ make configure

    $ CC=clang CXX=clang++ FC=gfortran \

      OBJC=clang OBJCXX=clang++ \

      ./configure

The "./configure" output will end by recommending

some packages to install with Homebrew. Follow

these recommendations.

Hmm. my gcc / clang version is 11.0 is newer. I wonder why it is trying to install gcc?

$ gcc --version

Could you post config.log ?

Apparently clang failed a test....

The complete file, please.
Thai little fragment is totally fine (it actually merely tests whether
-E is a correct switch :-))

From the log, it looks like you have a conda environment activated. 

Sage 8.9 does not support this.

Deactivate it to compile Sage, or try with the 9.1 release candidate.
