A lot of people have a lot of problems with Sage-9.2 on MacOS, installing pre-compiled or building from the source.
Sage-9.2 has several idiosyncrasies that for me are hard to explain. One - it deliberately refuses to work with Macports-installed packages, even though their main difference from similar ones installed via Brew is their location. How crazy is that? Second, pplpy-0.8.4 is "obtuse" enough to try compiling C++ file linear_algebra.cpp with clang instead of clang++, and then complain that CFLAGS that are (surprise!) C-specific, do not make sense for C++. Need I mention that it is impossible to locate clang but not clang++? Now, from generic criticisms to specific errors and logs. *Platform* *-* iMac 2020, Intel Core i9 CPU, 32GM RAM - macOS Catalina 10.15.7 - Xcode-12.3 (with command-line tools installed) in /Applications/Xcode.app, and separately installed CLT 12.3 in /Library/Developer/CommandLineTools. - Macports 2.6.4, with a ton of packages installed in /opt/local, which include clang-11, gcc-10, python38 and python39, and OpenSSL-1.1.1i. *Problems* 1. Sage-9.2 config refuses to use already-installed packages in /opt/local, spends sh*tload of time and bandwidth downloading what's already there (except that it downloads Python-3.8.5, and my machine has Python-3.8.6), and finally fails to compile that pile: 2. pplpy-0.8.4 uses clang (*not* clang++? Why?) to compile ppl/ linear_algebra.cpp files, and fails because on my machine CFLAGS differ from CXXFLAGS (surprise! one sets -std=gnu18, and other one sets -std=gnu++17). This bug should manifest on all the .cpp files. *Logs* The main log is 5.7 MB, so I don't want to post it unless asked to. Excerpts: Error building Sage. The following package(s) may have failed to build (not necessarily during this run of 'make all-build'): * package: pplpy-0.8.4 last build time: Dec 20 22:51 log file: /Applications/SageMath/logs/pkgs/pplpy-0.8.4.log build directory: /Applications/SageMath/local/var/tmp/sage/build/pplpy-0.8.4 and more specifically: [pplpy-0.8.4] creating build/temp.macosx-10.9-x86_64-3.8/ppl [pplpy-0.8.4] *clang* -Wno-unused-result -Wsign-compare -Wunreachable-code -DNDEBUG -g -fwrapv -O3 -Wall -Wno-unused -O3 -std=gnu18 -march=native -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.1.sdk -O3 *-std=gnu18* -march=native -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.1.sdk -Ippl -I/Applications/SageMath/local/lib/python3.8/site-packages/gmpy2 -Ippl -I -I/Applications/SageMath/local -I/Applications/SageMath/local/lib/python38.zip -I/Applications/SageMath/local/lib/python3.8 -I/Applications/SageMath/local/lib/python3.8/lib-dynload -I/Applications/SageMath/local/lib/python3.8/site-packages -I/private/var/folders/_l/4q83bg9j5ysb7qd1n9xpnb4h0000gn/T/pip-req-build-_4gwq_tw -I/Applications/SageMath/local/include/python3.8 -c ppl/linear_algebra.cpp -o build/temp.macosx-10.9-x86_64-3.8/ppl/linear_algebra.o [pplpy-0.8.4] error: *invalid argument '-std=gnu18' not allowed with 'C++'* [pplpy-0.8.4] error: *command 'clang' failed* with exit status 1 [pplpy-0.8.4] Building wheel for pplpy (setup.py): finished with status 'error' [pplpy-0.8.4] ERROR: Failed building wheel for pplpy BTW, why is it creating build for macosx-10.9 when the current version of the OS is 10.15, and SDK is for 11.1?
